TOODEE 2: A Two Dimensional Time Dependent Fuel Element Thermal Analysis Program.

摘要

TOODEE2is a two dimensional,time dependent fuel element thermal analysis program developed by staff of the Nuclear Regulatory Commission from the TOODEE Code. Written in FORTRAN IV language, TOODEE2was developed primarily as an evaluation tool to calculate fuel element thermal response during the refill and reflood phase of a loss-of-coolant accident in a pressurized water reactor. For small breaks the code may be used for the entire transient. This report contains descriptions of the applicable models used in TOODEE2, a detailed description of the input data,data options for evaluation model calculations (to meet requirements of 10CFR 50.43,Appendix K),sample input,and definition of input error and warning messages printed by the program.
