Simulation of a TMI-2 Type Scenario at the ROSA-IV Program's Large Scale Test Facility: A First Look

摘要

The Three Mile Island-2 (TMI-2) type scenario in a Westinghouse (W) type four loop pressurized water reactor (PWR) was studied in preparation for upcoming tests in the ROSA-IV Program's Large Scale Test Facility (LSTF). The LSTF is a 1/48 scale simulator of a W type four loop PWR with full scale component elevation differences. TMI-2 scenario simulation analyses were conducted to establish a pretest prediction data base for RELAP5 code evaluation purposes and to furnish a means of evaluating the LSTF's capability to simulate the reference PWR. The basis for such RELAP5 calculations and the similarities between the LSTF and reference PWR thermal-hydraulic behaviors during a TMI-2 type scenario are presented. (Atomindex citation 16:085985)
