【Abstract】 The analysis of long term cooling for a pool type reactor after shutdown is presented. The heat from fission is obtained by solving the neutron kinetic equation. The heat from fission product decay is evaluated according to the Chinese National Standard EJ/T 745-92. For thermal analysis, 1 D lumped parameter heat conduction mode is used, and a computer code is programmed, the appropriate parameters are chosen to analyze the behavior of a pool type test reactor. The calculation results agree well with the results from RETRON-02 calculation. The relationship among the maximum pool water temperature, the water inventory and heat transfer coefficient has also been investigated.更多还原
