President inaugurates Integrated Centre for Crisis Management for CBRN emergencies at BARC

President Ram Nath Kovind inaugurated Integrated Centre for Crisis Management (ICCM) at Bhabha Atomic Research Centre (BARC) in Mumbai, Maharashtra. The ICCM will help nation to respond more effectively to chemical, biological, radiological and nuclear (CBRN) emergencies. It will monitor radiological data from a network of 504 radiation sensors across the country.

Other launches

  • Multi-leaf collimator system: It has been developed by BARC. It is used radiotherapy as it enables gamma radiation to be exposed only on cancer-affected organs.
  • Trombay Chhattisgarh Dubraj Mutant-1: It is high-yielding dwarf variety of Dubraj mutant rice. It is 43rd high-yielding crop variety developed by BARC.

President Kovind also remotely inaugurated three other nuclear facilities of Department of Atomic Energy (DEA). They are

  • Metal fuel pin fabrication facility: It has been jointly developed by BARC and Indira Gandhi Centre for Atomic Research at Kalpakkam, near Chennai, Tamil Nadu. It will help to increase plutonium production in fast breeder reactors.
  • High-power electron beam melting furnace: It is jointly developed by scientists of BARC and Nuclear Fuel Complex. It will be used for nuclear and strategic applications.
  • Integrated enriched boron tri-fluoride gas generation facility: It was developed by Heavy-water Board in Odisha. It will be used in neutron detectors.

Bhabha Atomic Research Centre (BARC)

BARC is India’s premier nuclear research facility based in Mumbai, Maharashtra. It is multi-disciplinary research center with extensive infrastructure for advanced research and development. Its R&D covers entire spectrum of nuclear science, engineering and related areas. BARC’s core mandate is to sustain peaceful applications of nuclear energy, primarily for power generation.

India, Russia ink agreement to set up 25 Agro Irradiation Centres

India and Russia have signed an agreement for cooperation in the development of a network of 25 integrated infrastructure Agro irradiation centres.

The agreement was signed between Indian Agricultural Association, Hindustan Agro Co-Op Ltd (HACL) and United Innovation Corporation (UIC), a subsidiary of ROSATOM State Atomic Energy Corporation of Russia.

As part of the agreement, India-Russia joint venture (JV) will be formed in which HACL will have the majority 51% stakeholding. UIC will be a technology partner and will help set up the irradiation centres. In first phase 7 centers will be set up in Maharashtra in Sindhurg, Satara, Solapur, JNPT, Jalana, Napur and Pune.

Importance of Agreement

  • For the first time paves the way for establishment of network of integrated infrastructure irradiation centres in India to reduce agricultural losses.
  • These irradiation centres will help in treatment of perishable food items to improve shelf life and cut post-harvest losses.
  • It will further increase basket perishable items for irradiation process on a commercial scale ranging from flowers to fish.
  • Expand India-Russia cooperation in civil nuclear energy.

Why India needs strong network of Agro Irradiation Centres?

In India post-harvest losses in food and food grains are around 40-50%. It is primarily due to microbiological contamination, insect infestation, physiological changes due to sprouting and ripening, and poor shelf life. The wastage of fruits and vegetables including cereals, meat, pulses and flowers results in the annual loss estimated to be Rs. 2,50,000 crores. There is presence of few low level irradiation plants in the country which are not adequate.  So to reduce the losses in food and food grains and meet the demand it is necessary to increase strong network of agro irradiation centres.

What is food irradiation?

  • Food irradiation is a technology in which food products are subjected to a low dosage of radiation to treat them for germs and insects, increasing their longevity and shelf life.
  • It is the application of ionizing radiation to food in which energy is transmitted without direct contact in the targeted food.
  • The radiation can be emitted by a radioactive substance or generated electrically. The irradiated food does not become radioactive.
  • Radioisotopes are used as the source for the gamma rays. Generally cobalt-60 radioisotope is used as a radioactive source for gamma irradiation.
  • Then International Atomic Energy Agency (IAEA) recommends the irradiation doses for Food irradiation.
  • Benefits: Irradiation is equivalent to pasteurization for solid foods, but it is not the same as sterilization.
  • It does not reduce the nutritional value of food products and does not change their organoleptic properties and appearance.
  • The irradiation treatment of food and foodgrains preserves them for longer time, prevent the spread of invasive pests, delay/eliminate ripening or sprouting and reduce the risk of food borne illness.
