ID: CL-ILT-6502 Points: 1.00 An accident occurred that required the initiation of containment sprays due to elevated containment temperatures and pressures. After containment spray has been initiated the following containment/drywell conditions exist:

- Containment pressure 0.1 psig and lowering at rate of.05 psig/min

- Containment temperature 185°F

- Drywell temperature 250°F Which of the following actions is required and why?

A.

Stop containment spray to avoid exceeding negative containment design pressure.

B.

Continue containment sprays to prevent exceeding containment design temperature.

C.

Stop containment sprays due to entry into the unsafe region of the Containment spray initiation limit (Fig. O).

D.

Continue containment sprays to maintain containment pressure below pressure suppression pressure (Fig. N).

EXAMINATION ANSWER KEY 0901 NRC Exam Final CPS OPS MASTER Page: 4 of 171 15 October 2010 Distracters:

B is incorrect as containment sprays are not allowed for containment pressure below 0 psig.

C is incorrect because even though sprays should be stopped the reason is incorrect. Entry into the shaded region is allowed following initiation of sprays.

D is incorrect as containment sprays are not allowed for containment pressure below 0 psig.

High drywell condition is required as a permissive for containment spray initiation.

Per CPS 5041-6B, the standby air compressor should have auto-started at 80 psig (lowering); therefore, two are now running. Per CPS 5041-5C, the ring header isolations should close at 70 psig (lowering). The stem uses one minute as a way to ensure that all portions of the Plant Air system have had sufficient time to sense the lowered pressure, and to ensure that all affected ring header auto isolations have closed as a result.

EXAMINATION ANSWER KEY 0901 NRC Exam Final CPS OPS MASTER Page: 77 of 171 15 October 2010 General References 3105.05 3504.01 Explanation Per CPS 3105.05, Section 8.5.2. VARs to the grid translates to a lagging power factor. At 20,020 volts, the generator is operating at 91% of rated (.91 x 22,000 = 20,020). Section 8.5.2.2 Table shows rated voltage is 22,000. Operators determine that the maximum allowable MVA load is 91% of rated MVA. Section 8.5.2.2 Table shows Rated MVA is 1265 MVA. Therefore, the maximum allowable MVAs is 1151 MVA (.91 x 1265 = 1151). Per CPS 3504.01, Section 8.3.1, operators recognize that the degraded cooling condition on MPT C is the limiting concern. Operators determine that Table 1 applies (given that no operable cooling banks are available). Per the notes of Section 8.3.1, at 95°F air temperature, operators default to the higher temperature value (104°F), and the higher MVA load value (1282.2 MVA). The resulting time limit at this MVA load is 18 minutes.

General References 5067-7F Explanation

'B' SLC pump has started however the squib valve for 'B' did NOT fire as indicated by the continuity light being lit.

'A' SLC pump started and tripped as indicated by the suction valve being fully open and the amber light lit above the pump. During the start sequence the amber light is out until the breakers closes. 'A' SLC continuity light is lit and discharge pressure is well below the relief valve setpoint.

Answer is 'B' SLC pump injecting through A squib valve.
