ATTACHMENT I BVPS-2 FSAR Test Methods

1. The effectiveness'of the pressurizer sprays will be evaluated by de-energizing the pressurizer heaters and initiating pressurizer spray to determine the rate of pressure reduction.
2. After re-estab lishing normal operating pressure, the pressurizer spr ays will be isolated and the effectiveness of the pressurizer heaters will be evaluated by energizing the pressurizer heaters and determining the rate

. at which pressure increases.

3. Under simulated natural circulation conditions (i.e. one reactor coolant pump is operating not in a loop with presurizer spray or surge line) pressure will be reduced by turning off . pressurizer heaters and noting depressurization rate. Af ter restoring . pressure to nonnal, the heaters will be turned off and pressure reduced by use of auxiliary spray. The effects of changes in charging flow and stean flow on margin to saturation tenperature wilI_ be observed.

Acceptance Criteria

1. The rate of change or pressurizer pressure, during pressurizer spray and heater tests, are within design specification limits.
2. Under simulated natural circulation conditions, test data will be recorded' and wil l be av ail able for simulator update as necessary, wi th no acceptance criteria applied.
