SYSTEM AND METHOD FOR EVALUATING NUCLEAR REACTOR FUELING PLAN |
摘要 |
A nuclear reactor fueling plan evaluating system and method in which reactor shutdown margin evaluation are performed quickly and accurately. A fueling procedure formulating part and an input setting part having databases are included. A maximum worth control rod candidate selecting part having a control rod worth calculating means which inputs fuel loading and control rod patterns of each fueling act, inputs a relatively simple second physics model, calculates control rod worth from the difference between the degree of subcriticality of a reactor core in a state that all control rods are inserted and the degree of subcriticality of the reactor core in a state that a single control rod is withdrawn for each fueling step, and selects a determined number of maximum worth control rod candidates. A reactor shutdown margin calculating part inputs a subdivided first physics model and calculates reactor shutdown margin for each maximum worth control rod candidate.
