The mission of the AERB is to ensure the use of ionising radiation and nuclear energy in India does not cause undue risk to the health of people and the environment.

International Cooperation

AERB has been actively involved with various international bodies for exchange of information and co-operation in the field of regulation of nuclear activities for peaceful purposes. AERB experts have had been participating in various activities of IAEA and contributing at various forums. Examples are as follows:

Multilateral Cooperation
Multinational Design Evaluation Program (MDEP)

MDEP is a multinational initiative to develop innovative approaches to leverage the resources and knowledge of national regulatory authorities who are, or will shortly be, undertaking the review of new reactor designs. On April 4, 2012, India's AERB became the first new member in the MDEP since its inception in 2006. Prior to India joining the programme, MDEP membership included national regulatory authorities from Canada, China, Finland, France, Japan, the Republic of Korea, the Russian Federation, South Africa, the United Kingdom and the United States.

Nuclear Energy Agency (NEA) performs the Technical Secretariat function in support of the MDEP. The programme is governed by a Policy Group (PG), consisting of the heads of the participating organizations and implemented by a Steering Technical Committee (STC) and it's Working Groups (WGs).

The work of MDEP is carried out by design specific and issue specific Working Groups. Presently two design specific working groups (EPR-WG and AP1000-WG) have been established under MDEP to share information and co-operate on specific reactor design evaluation and construction. In addition to this, issues-specific (generic issues) working groups have also been established for the technical and regulatory area, which include: Vendor inspection Co-operation (VIC-WG), Codes and Standards (CS-WG) and Digital Instrumentation and Control (DIC-WG).

AERB actively participates in different WGs for mutual sharing of experience in different areas. In view of the envisaged programme of DAE which includes setting up of nuclear power plants of different technologies including EPR, India's participation in MDEP is considered to be very useful while performing the Safety Review for these reactor designs and carrying out licensing activities. The enhanced cooperation among regulators on an international platform is supposed to improve the effectiveness and efficiency of the regulatory design reviews of new reactors, leading to more efficient and more safety focused regulatory decisions.


The Nuclear Energy Agency (NEA) is a specialized agency within the Organisation for Economic Co-operation and Development (OECD), an intergovernmental organization of industrialised countries, based in Paris, France. The OECD is a unique forum in which its 35 member countries work together to create better policies for better lives.

The objective of the NEA is to assist its member countries in maintaining and further developing, through international co-operation, the scientific, technological and legal bases required for a safe, environmentally friendly and economi­cal use of nuclear energy for peaceful purposes. It provides authoritative assessments and forges common understandings on key issues as input to government decisions on nuclear energy policy and to broader OECD policy analyses in areas such as energy and sustainable development.


The main objective of the HYMERES Project is to improve the understanding of the hydrogen risk phenomenology in containment in order to enhance its modelling in support of safety assessment that will be performed for current and new nuclear power plants. With respect to previous projects related to hydrogen risk, the HYMERES project will introduce three new elements.

  • First, realistic flow conditions will be addressed. This will provide crucial information in the evaluation of the basic computational and modelling requirements (mesh size, turbulent models, etc.) needed to analyze a real nuclear plant.
  • Second, tests addressing the interaction of safety components will be performed. In general, previous investigations have focused on the activation of one safety component (spray, cooler, Passive Autocatalytic Recombiner (PAR), etc.) and showed their benefits and drawbacks. In the Project, it is proposed to study different combinations of "safety elements", e.g. the thermal effects created by two PARs, spray and cooler, spray and opening hatches, etc., operating simultaneously. The specification for the design of the safety components (e.g. full cone vs. hollow cone for sprays, PAR simulator power source time history, cooler design, etc.) will be defined based on consensus among the project participants.
  • Third, the system behaviour for selected cases will be addressed. In certain reactor types (e.g. various BWR, PWR or PHWRs designs), the hydrogen concentration build-up in the containment depends on the responses of different components in the system.

Consequently, investigations for safety relevant system behaviour related to BWRs, PWRs or PHWRs are proposed in the HYMERES Project. The knowledge expected to be gained from the HYMERES project will contribute to the improvement of the Severe Accident Management (SAM) measures for mitigating hydrogen risks. The test series proposed within the HYMERES Agreement, have been carefully defined, considering the Operating Agent's experience in other NEA projects (e.g. SETH and SETH-2). The HYMERES project is specifically aimed at topics of high safety relevance for both existing and future nuclear power plants.

AERB has been participating in this project through CFD simulation of various experiments carried out in PANDA and MISTRA test facilities.


Thermal-hydraulics, Hydrogen, Aerosols and Iodine (THAI) is a containment test facility operated by Becker Technologies, Germany. The experimental investigations carried out in the frame of previous OECD/NEA THAI projects (THAI and THAI-2, conducted during 2007-2009 and 2011-2014 respectively) have contributed significantly on hydrogen and fission product related issues in reactor containment under accidental conditions. Experiments envisaged in THAI-3 project are a follow on of the previous hydrogen and fission product related investigations conducted in THAI and THAI-2 projects. PAR performance under counter-current flow conditions, hydrogen combustion and flame propagation in two-compartment system, fission product re-entrainment from water pool at elevated temperature and re-suspension of fission product deposits upon impact of a high-energetic events will be studied during this project.

Indian participation in this project is still in approval stage.

International Atomic Energy Agency (IAEA)

AERB has been actively participating in the activities of IAEA. The staff of AERB participatesin various Technical and consultants meetings organised by IAEA on a range of topics for fuel cycle activities, radiation facilities, transportation of radioactive materials and illicit trafficking of radioactive materials. AERB has been participating in IAEA Coordinated Research Programme (IAEA-CRP) as well as IAEA International Standard Problem exercises (IAEA-ICSP).

AERB is the national coordinator for IAEA-INES and IAEA–IncidentReporting System(IRS). AERB participates in all activities related to theirfunctioning.

The staff of AERB also takes part in the development of IAEA documents. Review of the drafts of IAEA documents are also carried out by AERB when IAEA requests for feedback or comments fromthe member countries.

These interactions help AERB in keeping abreast with the developments in the related fields, safety issues and the evolving safety standards. The experience helps AERB in developing national standards andguidelines.
