Embodiment Construction

[0022] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] In the MOX fuel mixture, the operation volume of materials on the production line is very small, and the maximum post-batch operation volume of the production line is less than GB15146.2-2008 "Basic technical guidelines for the operation, processing and disposal of nuclear critical safety fissile materials of fissile materials outside reac...

Abstract

The invention provides an estimation method for a critical accident environment release source item of MOX fuel. The method comprises the following steps: (1) determining the total number of fissures;(2) determining the release of aerosol; (3) determining the release of inert gas and radioactive iodine; (4) determining the influence of ventilation and exhaust equipment and purification measures;And (5) calculating the critical accident radiation quantity. The method provided by the invention can estimate the critical accident release amount of the MOX fuel.

Description

technical field [0001] The invention belongs to the field of nuclear technology, and in particular relates to a method for estimating the environmental release source term of critical accidents of MOX fuel. Background technique [0002] Plutonium is an artificial radioactive isotope that does not exist in nature. Using plutonium as nuclear fuel can not only alleviate the shortage of uranium resources, improve the utilization rate of uranium, but also find a way to recycle a large amount of nuclear waste. The most effective way to utilize plutonium is to manufacture uranium-plutonium mixed (MOX: Uranium and Plutonium Mixed Oxide) ceramic fuel elements for nuclear reactors. MOX fuel is UO 2 and PuO 2 Uranium oxide plutonium fuel, PuO 2 The content is about 3%-5%. There are more than 40 years of experience in the manufacture and application of MOX fuel in the world. The safety and operation of nuclear power plant reactors using MOX fuel can reach the same level as uranium o...
