| titleOfInvention | A kind of compound modification method of presurized water reactor few group constant history effect |
| abstract | A kind of compound modification method of presurized water reactor few group constant history effect, steps are as follows: step 1: in reactor core, burnup calculating is carried out using the method for Predictor Corrector, to obtain the atom cuclear density of each nucleic under real history；Step 2: being based on 233 U、 235 U、 239 Pu and 241 Tetra- kinds of critical nuclide atom cuclear density of Pu are modified few group of microscopic cross in the difference of typical condition and actual motion history；Step 3: the amendment for few group of microscopic cross of amendment and step 2 in conjunction with step 1 for atom cuclear density carries out compound amendment to the history effect of few group of macroscopic cross sections；Step 4: by few crowd of macroscopic cross section Σ under the actual motion history of acquisition actual Three-dimensional reactor core calculation procedure is passed to, more accurate calculated result can be obtained；One aspect of the present invention calculates the deviation for eliminating atom cuclear density by carrying out in reactor core to the atom cuclear density of each nucleic in real time；On the other hand it utilizes 233 U、 235 U、 239 Pu and 241 The difference of tetra- kinds of critical nuclide atom cuclear density of Pu reflects the difference of power spectrum history, and then eliminates the deviation of few group's microscopic cross. |
