RTI and Nuclear Energy: What DAE and AERB Must Disclose — and What Section 8(1)(a) Shields

India's nuclear establishment occupies an unusual position in the landscape of government transparency. On the one hand, the Department of Atomic Energy (DAE) and the Atomic Energy Regulatory Board (AERB) are public authorities like any other Central Government body — created by law, funded by the public, exercising statutory powers. On the other hand, the nuclear sector sits astride national security considerations that give both the government and the courts reason to treat certain categories of nuclear information differently from, say, the records of a public works department.

The Right to Information Act, 2005 applies to DAE and AERB without qualification. Neither body is listed in the Second Schedule of the RTI Act — the schedule that identifies organisations exempt from the Act altogether. But the RTI Act's Section 8(1)(a) — the national security exemption — is the provision that creates the real friction in nuclear-related RTI. Understanding where that provision applies, where it does not, and how to frame requests that are likely to succeed is the purpose of this guide.

DAE, AERB, and NPCIL as Public Authorities

The Department of Atomic Energy is a Department of the Government of India. Unusually, it functions directly under the Prime Minister rather than under a Cabinet Minister heading a separate ministry. DAE was established under the Atomic Energy Act, 1962, and it oversees the full spectrum of India's civil and strategic nuclear programme.

The Atomic Energy Regulatory Board (AERB) was constituted by the Government of India in 1983 under the Atomic Energy Act, 1962. Its mandate is to regulate radiation safety and nuclear safety for civilian uses — nuclear power plants, research reactors, radiation facilities in hospitals and industry, and nuclear fuel cycle facilities. AERB operates as India's nuclear regulatory authority, with functions analogous to the Nuclear Regulatory Commission in the United States or the Office for Nuclear Regulation in the United Kingdom.

Both DAE and AERB are Central Government bodies. Under Section 2(h) of the RTI Act, 2005, a "public authority" includes any authority or body established or constituted by or under a law made by Parliament. Both bodies were established under the Atomic Energy Act, 1962, a law made by Parliament. Both are therefore unambiguously public authorities under the RTI Act.

The Nuclear Power Corporation of India Ltd (NPCIL) — the public sector company under DAE that constructs and operates most of India's nuclear power plants — is also a public authority. As a government company that is substantially funded and controlled by the Central Government, it falls within the RTI Act's definition. So does the Bhabha Atomic Research Centre (BARC), the premier nuclear research institution under DAE, and the other constituent units of the DAE family: the Indira Gandhi Centre for Atomic Research (IGCAR), the Raja Ramanna Centre for Advanced Technology (RRCAT), and the Nuclear Fuel Complex (NFC).

RTI applications to all of these bodies are filed at rtionline.gov.in, since all of them are Central Government public authorities. The ₹10 fee under the RTI (Regulation of Fee and Cost) Rules, 2005 applies and is waived for BPL cardholders. Responses are due within 30 days under Section 7(1) of the RTI Act (48 hours where the information concerns the life or liberty of a person, under the proviso to Section 7(1)). First Appeal lies to the body's own First Appellate Authority under Section 19(1) within 30 days of the date of decision or expiry of the response period. Second Appeal goes to the Central Information Commission (CIC) under Section 19(3).

The Atomic Energy Act, 1962 and Secrecy Obligations

The Atomic Energy Act, 1962 is the primary statute governing nuclear energy in India. It empowers the central government to produce, develop, use, and dispose of atomic energy; to carry out research into matters connected with atomic energy; to acquire minerals and materials; and to prescribe safety regulations for radiation and nuclear facilities.

Section 18 of the Atomic Energy Act imposes secrecy obligations on persons employed in atomic energy matters. It prohibits such persons from communicating, other than in the performance of official duties, any information relating to atomic energy that has been designated secret or confidential.

This provision, however, does not override the RTI Act. The Right to Information Act, 2005 was enacted by Parliament as a later law, and it contains its own comprehensive framework for disclosure and exemption that governs the obligations of public authorities as such — as distinct from the personal obligations of individual employees under the Atomic Energy Act. The RTI Act's Section 22 states explicitly that its provisions have effect notwithstanding anything inconsistent with them in any other law for the time being in force. The applicable framework for RTI applications to DAE, AERB, or NPCIL is the RTI Act, not Section 18 of the Atomic Energy Act.

The consequence is significant: DAE and AERB cannot respond to an RTI application by simply invoking Section 18 of the Atomic Energy Act as a blanket ground for refusal. They must engage with the RTI Act's own framework — and in particular, with the specific exemptions that the RTI Act provides — to justify any refusal to disclose.

Section 24 of the RTI Act: Is DAE Exempt?

Section 24 of the RTI Act is a provision that exempts certain intelligence and security organisations from the Act's coverage entirely (except for allegations of corruption or human rights violations). The organisations covered by Section 24 are those listed in the Second Schedule to the RTI Act. The Central Government can also, by notification, add organisations to the Second Schedule.

The Second Schedule, as enacted, lists bodies such as the Intelligence Bureau (IB), the Research and Analysis Wing (RAW), the Directorate of Revenue Intelligence, the Central Economic Intelligence Bureau, the National Technical Research Organisation (NTRO), the National Security Guard (NSG), the Border Security Force, and a number of other specified organisations. It is a closed, enumerated list.

The Department of Atomic Energy is not listed in the Second Schedule. AERB is not listed. NPCIL, BARC, IGCAR, RRCAT — none of these bodies appears in the Second Schedule. This is not a minor technical point. It means that none of these nuclear sector bodies can claim blanket exemption from the RTI Act under Section 24. They have all the obligations of an ordinary public authority under the Act. They must respond to RTI applications within the stipulated time. They must designate CPIOs. They cannot simply refuse to engage with an RTI query by claiming they are exempt organisations.

Where they can decline to disclose, they must do so on the basis of specific, applicable exemptions within Section 8(1) of the RTI Act — and the primary exemption they are likely to invoke is Section 8(1)(a).

Section 8(1)(a): The National Security Exemption

Section 8(1)(a) of the RTI Act exempts from mandatory disclosure "information, disclosure of which would prejudicially affect the sovereignty and integrity of India, the security, strategic, scientific, or economic interests of the State, relation with foreign State or lead to incitement of an offence."

This is a broad provision. "Scientific interests of the State" and "strategic interests of the State" are phrases that, read expansively, could cover a very wide range of information held by DAE and its constituent bodies. The challenge with Section 8(1)(a) is that its scope is not self-defining, and public authorities in the nuclear sector have historically tended to invoke it broadly.

At the same time, Section 8(1)(a) is not a general licence to withhold any information that relates to nuclear energy. The exemption is conditional: information must be such that its disclosure "would prejudicially affect" the listed interests. That is a causal, consequentialist test — not a categorical one. An AERB internal regulation on the safety of medical radiography units does not prejudicially affect national security by its disclosure. A NPCIL annual report on reactor generation capacity does not prejudicially affect the strategic interests of the State. The critical analytical move is to identify what information, if disclosed, would genuinely cause the kind of prejudice the provision requires — and what information would not.

What DAE, AERB, and NPCIL Must Disclose

There is a meaningful and substantial body of nuclear-sector information that falls clearly outside the Section 8(1)(a) exemption and that DAE, AERB, and NPCIL are legally obliged to disclose in response to RTI applications.

AERB's regulatory framework and standards. AERB is responsible for publishing safety codes, safety guides, and safety manuals that constitute the regulatory requirements for nuclear and radiation facilities in India. These documents — covering nuclear power plant design safety, radiation protection, industrial radiography safety, hospital radiation sources, and transport of radioactive materials — are published proactively by AERB on its website. This is Section 4 suo motu disclosure in practice. Where specific documents are not proactively published, RTI is the appropriate mechanism. There is no conceivable national security argument against disclosing the radiation protection standards that a hospital's radiation therapy unit must comply with.

AERB site inspection and regulatory activity reports for non-military facilities. AERB conducts regulatory inspections of nuclear power plants, research reactors, radiation facilities in hospitals and industries, and fuel cycle facilities. For civilian facilities — as distinct from defence establishments — AERB's inspection findings, regulatory notifications to operators, and compliance reports are regulatory information that bears directly on public safety. AERB has over the years published aggregate safety performance data. Specific inspection findings for a facility in response to an RTI application are disclosable unless specific information within a report meets the Section 8(1)(a) test.

AERB Annual Safety Performance Indicators. AERB publishes annual safety performance indicator reports for nuclear power stations. These reports contain facility-level data on unplanned reactor trips, safety system unavailability, collective radiation dose to workers, and radioactive effluent releases. This information is proactively published, and RTI can be used to request historical years or specific data points not covered in published reports.

NPCIL generation and safety data. NPCIL publishes annual reports with plant-wise generation data, capacity utilisation factors, and safety performance summaries. NPCIL's budget and expenditure, procurement contracts, and infrastructure investment decisions at plant sites are all subject to RTI in the standard way. The fact that a contract relates to a nuclear power plant does not convert a procurement record into a national security secret.

Budget and expenditure of DAE and its constituent units. DAE's budget allocations — published in the Union Budget documents and accessible through RTI in more granular form — cover expenditure across nuclear power programmes, nuclear research, nuclear medicine and radiation safety, and support to various DAE institutions. This financial information concerns the use of public money and is disclosable.

Recruitment and selection records. DAE, AERB, NPCIL, BARC, and other constituent institutions conduct highly competitive recruitment processes — the DAE Graduate Fellowship scheme, the BARC Training School admissions, direct recruitment to scientific posts. Information about selection criteria, cut-off scores, interview panel composition, and numbers selected is administrative record-keeping of the kind that RTI routinely reaches. The fact that the employer conducts nuclear research does not exempt it from answering questions about its own recruitment decisions.

Environmental monitoring data near nuclear power plant sites. Residents living in the vicinity of nuclear power plants — Tarapur in Maharashtra, Rawatbhata in Rajasthan, Kalpakkam in Tamil Nadu, Narora in Uttar Pradesh, Kakrapar in Gujarat, Kaiga in Karnataka, and Kudankulam in Tamil Nadu — have legitimate interests in knowing what radiation monitoring data is collected in their areas, what radioactive discharges occur, and what trends are visible in long-term environmental monitoring. AERB requires nuclear facilities to conduct and report environmental monitoring. Some of this is published. Where it is not, RTI from nearby residents constitutes one of the strongest public interest cases in the nuclear domain, and Section 8(2) of the RTI Act — which provides that even exempt information may be disclosed if the public interest in disclosure outweighs the harm — is directly relevant to requests for radiation monitoring and effluent data from communities near nuclear sites.

Reportable events and near-miss records. AERB requires nuclear facilities to report events that deviate from normal safety parameters — reactor trips, equipment failures, unexpected radioactive releases, near-miss situations. Aggregate data about such events (numbers, categories, trends) is regularly published by AERB. Specific reportable event notifications — which are administrative documents generated in the course of regulatory oversight — are disclosable where the specific content of an event report does not meet the Section 8(1)(a) threshold. Citizens and researchers who want to understand the safety record of a particular plant over time can legitimately seek this data.

What Is Likely Exempt Under Section 8(1)(a)

It would be misleading to present RTI access to nuclear sector information as uncomplicated. There is a genuine core of nuclear information where Section 8(1)(a) applies properly and legitimately, and the courts and the CIC have recognised this.

Nuclear weapons-related information. India has not officially declared whether it maintains a nuclear weapons programme as such, and the full details of India's strategic nuclear programme — the nature and quantity of weapons-grade nuclear material, weapons design and configuration, deployment arrangements, and the details of India's 1974 Pokhran test and the 1998 Pokhran-II tests — fall within the heartland of Section 8(1)(a). Disclosing weapons-grade material quantities or locations would prejudicially affect the security, strategic, and scientific interests of the State in a direct and unambiguous way. RTI applications seeking this category of information are correctly refused under Section 8(1)(a).

Security arrangements at nuclear facilities. The physical protection of nuclear power plants, research reactors, and nuclear fuel storage facilities from sabotage and theft is a genuine national security matter. Security protocols, guard deployment, perimeter protection measures, and vulnerability assessments at nuclear facilities are appropriately withheld under Section 8(1)(a). This is not an over-broad invocation of the exemption; it is exactly the kind of information the provision was designed to protect.

Specific reactor design details with proliferation implications. Detailed technical design parameters that could assist a state or non-state actor in building nuclear devices — specific enrichment data, plutonium separation records, criticality parameters for weapons-relevant materials — are appropriately withheld. The distinction from general reactor safety standards (which are disclosable) lies in whether the information could enable weapons production or attack on a facility.

Foreign nuclear intelligence. Any information that DAE or its institutions hold relating to foreign nuclear programmes, intelligence assessments of nuclear threats, or diplomatic communications about nuclear matters falls within Section 8(1)(a)'s "relation with foreign State" limb and the broader security and strategic interests limb.

The Radiation Safety and Transparency Tension

The most practically important tension in nuclear RTI is not about weapons. It is about the safety of people who live and work near civilian nuclear facilities.

India's nuclear power programme has expanded significantly over the decades, and communities near plants have raised questions about radiation exposure, emergency preparedness, and the environmental impact of plant operations. These are legitimate questions that go to the health and livelihoods of real people. The legal framework provides a meaningful basis for pursuing them through RTI.

Section 8(2) of the RTI Act is particularly relevant here. It provides that "a public authority may allow access to information, if public interest in disclosure outweighs the harm to the protected interests." Even for information that a public authority considers to fall within an exemption, the public interest test under Section 8(2) must be applied. Information about radiation levels in residential areas around a plant, or the number and nature of reportable events at a specific facility, presents a compelling public interest case — the health and safety of affected communities — that should weigh significantly in the Section 8(2) balance.

The practical difficulty is that public information officers at nuclear sector bodies have sometimes applied Section 8(1)(a) broadly to decline queries that do not genuinely meet the "would prejudicially affect" standard. If a CPIO refuses to provide radiation monitoring data for a residential area near a nuclear plant on the ground that it affects "strategic interests," that refusal is worth challenging at First Appeal and, if necessary, at the CIC. The CIC has in various contexts recognised that blanket invocations of Section 8(1)(a) — without demonstrating how specific information meets the causal test — do not satisfy the RTI Act's requirements.

BARC: Research Institution and Public Authority

The Bhabha Atomic Research Centre at Trombay, Mumbai, is India's largest nuclear research centre. It conducts research across nuclear technology, nuclear fuel, isotope production for medical and industrial use, materials science, and reactor technology. It is also engaged in work that straddles civil research and India's strategic programme.

As a body established under the aegis of DAE and funded by public money, BARC is a public authority under Section 2(h) of the RTI Act. RTI can legitimately reach BARC for: selection and recruitment records (including BARC Training School admissions, a highly competitive programme that thousands of graduates apply to every year); budget allocations and expenditure on research programmes in non-sensitive areas; administrative records about service conditions, transfers, and promotions of staff; published research reports and technical documents that BARC makes publicly available; and records about BARC's radiological services and isotope supply operations.

For the elements of BARC's work that directly connect to India's strategic nuclear programme, Section 8(1)(a) will legitimately apply. The line between civil nuclear research (where RTI reaches) and strategic programme work (where it may not) is not always crisp, and applicants should expect that some BARC queries will be refused on this ground. But the refusal, to be valid, must be specific about how the particular information requested meets the Section 8(1)(a) standard — not a blanket assertion that BARC does sensitive work.

Practical Guidance: Filing Nuclear-Sector RTI

Given everything above, how should a citizen, journalist, researcher, or community resident frame an RTI application to DAE, AERB, or NPCIL that has a realistic chance of succeeding?

Be specific, not sweeping. A broad request for "all safety records" at a nuclear power plant is almost certain to be refused, partially because it is genuinely unwieldy to respond to and partially because it will invite a broad invocation of exemptions. A targeted request for a specific document, a specific data series, or a specific time period is far more productive.

Use AERB's own published framework as your reference. AERB publishes safety performance indicators, annual reports, and regulatory documents. If you know that AERB publishes a specific category of data, you can ask for the specific year's report or the data underlying a published figure. This makes it harder to refuse on grounds of sensitivity, since AERB itself has acknowledged the category of data as publishable.

Frame requests around administrative and regulatory functions, not technical nuclear physics. Questions about how a regulatory decision was made, what criteria were applied in approving or rejecting a licence, what the inspection schedule is for a facility, and how a complaint was handled are administrative questions. They are far less exposed to Section 8(1)(a) than questions about technical specifications of reactors or nuclear material inventories.

Invoke the public interest for environmental and health data. If you are seeking radiation monitoring data near a plant or data about radioactive effluent discharges, make explicit in your application that you are a resident in the vicinity of the facility and that the information bears directly on your health and that of your community. This establishes the public interest argument under Section 8(2) upfront, and it frames the CPIO's task as one of balancing — not simply of classification.

Specific examples of well-framed RTI questions for nuclear sector bodies:

• "Please provide the AERB Annual Safety Performance Indicators report for plant name for the year year, as submitted by the plant operator to AERB."
• "Please provide the total number of reportable events at plant name reported to AERB during the period date range, along with the category classifications used."
• "Please provide the AERB Safety Code applicable to nuclear power plants in India regarding core damage frequency requirements (document title and number)."
• "Please provide the radiation monitoring data collected at specific monitoring station near plant for the period date range, as maintained by plant operator/AERB."
• "Please provide the criteria and cut-off scores applied in the selection of year batch of BARC Training School recruits in the discipline discipline."
• "Please provide DAE's budget allocation and actual expenditure for department/programme for the financial year year."
• "Please provide the emergency preparedness plan currently in force for plant site in relation to the public and residential communities within distance of the plant."

A Note on the Civil Nuclear Liability Act, 2010

The Civil Liability for Nuclear Damage Act, 2010 (CLND Act) established India's framework for liability in the event of a nuclear accident. The operator of a nuclear installation is liable for nuclear damage up to a specified limit, and the central government carries liability beyond that amount.

Records relating to the implementation of the CLND Act — insurance arrangements entered into by NPCIL, the scope of coverage for nuclear incidents at specific plants, the number and nature of claims made under the Act (if any), and the procedures for notification of nuclear damage — are administrative and legal records of the kind that RTI can reach. They involve NPCIL and DAE as parties to legal and financial arrangements entered into using public resources. These records do not engage Section 8(1)(a) in any obvious way. They are commercial and legal records that bear on public accountability.

Filing Your RTI Application

DAE, AERB, NPCIL, BARC, and all other Central Government nuclear sector bodies are public authorities under the RTI Act. RTI applications are filed at rtionline.gov.in. The ₹10 filing fee applies under the RTI (Regulation of Fee and Cost) Rules, 2005, and is waived for BPL cardholders.

If a CPIO refuses your application, you may file a First Appeal to the body's First Appellate Authority under Section 19(1) of the RTI Act within 30 days of the date of decision or expiry of the 30-day response period, whichever is applicable. If the First Appeal fails or is ignored, you may approach the Central Information Commission under Section 19(3) of the RTI Act for a Second Appeal. A CPIO who wilfully refuses to provide information that should have been provided may be penalised under Section 20.

The nuclear sector is among the more challenging domains for RTI in India — not because DAE and AERB are exempt from the Act, but because the Section 8(1)(a) exemption is legitimately broad and its application in the nuclear domain genuinely raises hard questions of national security. The answer is not to avoid filing RTI against nuclear bodies; it is to file with precision and to understand, from the outset, which categories of information the RTI Act's architecture of transparency genuinely reaches.

DAE and AERB are Central Government public authorities. RTI applications to them, to NPCIL, to BARC, and to other DAE institutions are filed at rtionline.gov.in, with the Central Information Commission (CIC) as the second appeal authority. If you are preparing an RTI application to a nuclear sector body — whether about radiation safety near your community, AERB's regulatory standards, NPCIL's operations at a power plant, or a recruitment process at BARC — RTISathi.com has guides and sample formats for Central Government RTI applications that can help you frame a focused, effective request.
