Analysis of PKL test K9 by THYDE-P code

An analysis of PKL Test K9 is made by the THYDE-P code. Test K9 is the Standard Problem No.10 of Committee on the Safety of Nuclear Installations (CSNI) in the Nuclear Energy Agency (NEA), OECD. The objective of Test K9 is to investigate gravity-feed refill and reflood processes following a double-ended guillotine break in a cold leg with emergency cooling water being injected into the intact cold legs. THYDE-P is a code to analyze both the blow-down and refill-reflood phases of loss-of-coolant accidents (LOCAs) of pressurized water reactors (PWRs). In this report, calculated results are compared with the experimental data and discussed for the purpose of verification study and model development of THYDE-P. A good agreement with the experimental data was obtained using the best estimate (BE) options. (author)
