Shutdown Cooling Temperature Perturbation Test for Analysis of Potnetial Flow Blockages

Abstract

This paper details the method and results of the "shutdown cooling test" in October 1995. This novel rest was conducted at PLGS while the reactor was shutdown and shutdown cooling (SDC) water was recirculating to find potential channel blockages resulting from the introduction of wood debris. This rest discovered most of the channels that contained major wood and metal debris.
