BWR REFILL-REFLOOD PROGRAM - SINGLE HEATED BUNDLE EXPERIMENTAL TASK PLAN.

An experimental task plan for the Single Heated Bundle Task of the BWR Refill-Reflood Test Program is presented. The test program is designed to demonstrate the applicability of adiabatic steam injection to simulate the vaporization from heated rods in a bundle and will assess the validity of scaling from LOCA transient pressures to conditions in an atmospheric pressure test facility. The technique for determining adiabatic steam injection rates for the Lynn 30 degree Sector Steam Test Facility is also developed. Individual test conditions, the measurement plan, and the data utilization are discussed. In vol. 2 an experimental task plan for the separate effects bundle tests of the Single Heated Bundle Task in the BWR Refill-Reflood Test Program is presented. The tests will provide core spray and reflood heat transfer data and will investigated BWR refill-reflood controlling phenomena to support model development tasks in the BWR Refill-Reflood Program. Individual test conditions, the measurement plan and data utilization are discussed.
