NEA-1554 ZZ-PWR-MSLB.

1. NAME OR DESIGNATION OF PROGRAM:  ZZ-PWR-MSLB.

3. DESCRIPTION OF PROGRAM OR FUNCTION

- PWR-MSLB is a Main Steam-Line Break (MSLB) benchmark problem derived from the reactor geometry and operational data of the Three Mile Island Unit 1 (TMI-I) nuclear power plant. The objective of the benchmark is to verify the capability of coupled neutronics - thermal-hydraulics code systems to analyse complex transients with coupled core-plant interaction, and to fully test the thermal-hydraulic coupling. A three dimensional neutronics core model has been defined. The benchmark consists of three exercises:
1. Point kinetics plant simulation
2. Coupled neutronics/core thermal-hydraulics evaluation of core    response from a multi-dimensional (3-D) perspective
3. Best-estimate coupled core - plant transient modeling
This package contains the text of the four reports produced, the first one of which contains the specification, tables, pictures and numerical data  files required for the modeling of the MSLB event.
