Restriction of Iodine Release under Severe Accident Conditions at NPP MIR.1200
نویسندگان
چکیده
Iodine radionuclides in accident releases under severe accident conditions at NPP with VVER are the most radiationimportant with a view to population dose generation at the beginning of the accident. To decrease radiation consequences of severe accidents the technical solutions for severe accidents management have been proposed in MIR.1200 project, with consideration of the measures for suppression of volatile iodine forms generation in the containment. Behavior dynamics of different iodine forms in the containment under severe accident conditions has been analyzed for the purpose of these technical solutions justification. Keywords—Iodine radionuclides, VVER, severe accident.

Risk Assessment of the Thyroid Cancer within the Problem of Radiation Protection for the Reactor Accidents
INTRODUCTION Nuclear power reactors have a large inventory of radioiodine among other radionuclides. In the event of an accident in an operating NPP involving a release of radioactivity, the iodine isotopes will be among the first fission products to be released. Radioiodine isotopes cumulate in the thyroid gland. Therefore protection of the thyroid is one of the most important issues of emerge...

The Fukushima Daiichi Nuclear Power Plant (NPP) 1 was severely damaged from the chain reaction of the Great East Japan Earthquake and Tsunami on 11 March 2011, and the consequent meltdown and hydrogen gas explosions. This resulted in the worst nuclear accident since the Chernobyl accident of 1986. Just as in the case of Chernobyl, emergency workers were recruited to conduct a wide range of task...

After the Fukushima Daiichi nuclear power plant (NPP) accident, new regulatory requirements were enforced in July 2013 and a backfit was required for all existing nuclear power plants. It is required to take measures to prevent severe accidents and mitigate their radiological consequences. The Regulatory Standard and Research Department, Secretariat of Nuclear Regulation Authority (S/NRA/R) has...
متن کاملPublic Perceptions of the Iodine Tablets Distribution Around French Nuclear Power Plants
In April 1996 the French Ministry of Health decided to distribute stable iodine tablets to the population living in the vicinity of all nuclear power plants (NPP) in France. In case of a severe nuclear accident, the intake of stable iodine would prevent irradiation of the thyroid by the radioactive iodine released by the plant. This preventive distribution began in late 1996 around four pilot s...

Water deficit is an important factor limiting crop growth all over the world. In order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. The experiments were carried out at the Agricu...
