Embodiment

[0037] Taking the high temperature gas-cooled reactor nuclear power plant demonstration project (HTR-PM) new fuel road transportation as an example, the implementation of the method is specifically described.

[0038] According to formula (2), step by step determine the relevant quantities in the transport of radioactive materials:

[0039] V is 36 million yuan / single transportation (up to 36 packages are transported in a single time, and the fuel element in each package is worth 1 million yuan), which is converted to 5.4 million US dollars according to the current exchange rate;

[0040] α is conservatively taken as $100,000 / (person · Sv);

[0041] K is taken as 10 6 ;

[0042] From this we get R obj 5.4×10 -5 Person · Sv / Single Transport.

[0043] The PSA analysis of HTR-PM new fuel road transport showed that the overall radiation risk R was 4.96×10 -10 Person · Sv / Single Transport. It can be seen that R≤R obj , so the HTR-PM new fuel road transportation meets the qu...

Abstract

The invention belongs to the field of safety evaluation for radioactive substance transportation, and specifically relates to a method for determining a quantitative safety goal of radioactive substance transportation. In the method, the concept of [alpha] in a cost-benefit analysis method in radiation protection optimization is utilized, a radiation risk target value of radioactive substance transportation is calculated, and the calculated radiation risk target value is compared with a radiation risk value of a probabilistic safety assessment result to determine whether the radioactive substance transportation process meets the quantitative safety goal or not. The method is simple in logic, convenient to operate and applicable to determining the quantitative safety goal for transportationof various types of radioactive substances.

Description

technical field [0001] The invention belongs to the field of safety evaluation of radioactive article transportation, and particularly relates to a method for determining a quantitative safety target for radioactive article transportation. Background technique [0002] The United States is the first country in the world to quantify the safety objectives of nuclear power plants, and it is also the first country to combine deterministic and probabilistic methods in the study of technical safety objectives. After the Three Mile Island nuclear accident in 1979, the US Nuclear Regulatory Commission (NRC) conducted a study of quantitative safety objectives. The NRC proposes two quantitative safety goals (quantitative health goals), which are often referred to as "two thousandths": [0003] (1) The possible acute risk of death from a reactor accident to individuals or groups of residents near the nuclear power plant should not exceed 0.1% of the acute risk of death generally exper...
