Safety Research Institute

 
 

 

The Atomic Energy Regulatory Board (AERB) was constituted on November 15, 1983 to carry out certain regulatory and safety functions under the Act. The mission of the Board is to ensure that the use of ionizing radiation and nuclear energy in India does not cause undue risk to health and the environment. Currently, the Board consists of a full-time Chairman, an ex-officio Member, three part-time Members and a Secretary.

 

The Safety Research Institute (SRI) is a step of Atomic Energy Regulatory Board towards enrichment of nuclear safety culture in the nuclear power plants and R&D facilities of DAE. AERB plays the key role, in perspective of safety, to review, enforce standards and authorize sitting, designing, construction, operation and decommissioning of nuclear facilities. With a view to further strengthening its regulations AERB commissioned SRI at Kalpakkam in February 1999. It is a forum where research groups and regulators come together for formulation and implementation of research programme set forth to resolve safety related issues.

 

The primary objective of SRI is to build a unique research base in areas which are pertinent to safety functions of AERB in a way complementary to the ongoing R&D activities of DAE units. These areas include nuclear power plant safety, fire safety, industrial and environmental safety. The main thrust of research and developmental activities in SRI are :

 

  • To develop models, methodologies and knowledge base required for quantitative assessment of risks associated with the operation of nuclear fuel cycle facilities.
  • To generate/collect data needed for safety assessment.
  • To provide a technical forum for joint research among power plant personnel, research groups and regulatory functionaries in safety related fields.
  • To organize regular programmes of technical meeting and training courses for different target groups on a variety of topics for enhancement of safety performance.

 

The Activities

 

The current research activities of SRI relate to probabilistic safety assessment, radiological safety studies, remote sensing and geographic information system facility and radionuclides migration studies:

 

Nuclear plant safety is identified as one of the main areas of research and development activity in SRI. An important tasks being carried out in regulatory review of nuclear and radiological facilities is the assessment of adequacy of shielding provided to protect radiation workers.

 

One of the aims of AERB-SRI is to support environmental decision-making within AERB and DAE as a whole, by generating and disseminating information about the state of environment in and around DAE installations. The effort is towards providing relevant inputs to Environmental Impact Assessment (EIA) studies of Nuclear Power Plants (NPPs).

 

Disposal of High Level Radioactive Waste in deep geological formations is considered worldwide as the suitable option to safeguard the man and environment for extended period. An attempt has been made to simulate migration of radio nuclides through the rock mass in a small geo-technical centrifuge.

 

SRI promotes inter-institutional co-ordinated research programme in areas of interest to regulatory functions of AERB. One such collaborative research programme initiated by SRI aims at development of a realistic atmospheric dispersion model suitable to coastal sites.

 

SRI is also poised to carry out R&D activities in the areas of Nuclear Plant Safety and Environmental Safety Studies.

 

SRI provides a forum for designers, operators, research group and regulators to come together for exchange of information and expertise.

 

SRI has taken up commissioning of a national depository of computer codes pertaining to safety analysis and hazard evaluation.

 

NISARG - RUNA: Kitchen waste(Biodegradable) based bio-gas plant

 

 

A large quantity of biodegradable waste such as kitchen waste is generated everyday. It is estimated that about 400-500 gm of biodegradable waste is generated per person per day. In Mumbai about 3000 tonnes of biodegradable waste is generated per day. All this waste is left in dumping grounds that may cause health hazards.

 

BARC’s Nisarg-runa plant for solid waste management offers a “Zero garbage, Zero effluent” method for waste management. Two such plants have been installed at BARC and the residential complex, Anushaktinagar, for environmental friendly disposal of the waste generated in kitchens of various canteens in the premises.

 

A conventional plant can handle only gobar & / or human waste. Nisarg-runa plant can process almost any biodegradable waste including kitchen waste, paper, grass, gobar, dry leaves etc. There is a good potential for energy generaton in this biphasic biomethanation plant.

 

A substantial portion of our biodegradable waste is food waste (38-40%) which is used to generate methane. This methane gas can be used as fuel for domestic purposes or in vehicles. The vegetable waste and paper waste yield manure. Manure obtained from such waste has high nitrogen contents. This manure acts as an excellent soil conditioner. The plant returns as organic manure that is 10% of the total waste processed. The carbon to nitrogen ratio of this manure is 12:1 (similar to fertile land). It has phosphorous, potassium, iron and magnesium in small quantities. It is weed free and does not have any offensive smell.
