AGENDA

TOPIC: Mass and Energy Release for Containment Pressure Analysis

1. Use of CRAFT Post End of Blowdown (see attached memo). Comparison of CRAFT vs. REFLOOD for post blowdown period.

2. Quenching of Steam by ECCS Fluid.

3. Carryover Rate Fraction (CRAFT vs. FLECHT data).

4. Rate of Energy Release into Containment:

a. Treatment of Stored Heat

b. Treatment of Secondary System Heat
