Can St. Lucie Unit I achieve cold shutdown within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> with loss of offsite power?
St. Lucie Unit I can achieve cold shutdown within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> with loss of offsite power.
ls the Refueling Water Storage Tank (RWST) indication included on the alternate shutdown panel?
RWST level indication is not included on the alternate shutdown panel.
The RWST level is a
Technical Specification requirement, and unless there is a system failure (pipebreak) concurrent with the fire, there is much more than adequate water to achieve cold shutdown.
Furthermore, within the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> cold shutdown requirement, operators can verify RWST tank level at the local instrumentation for the tank.
Therefore RWST level indication is not necessary on the alternate shutdown panel.
Are fuses pulled to close the-PORV's, steam generator dump valves, and the'main steam isolation valves?
Fuses are not pulled to close the PORV's steam generator dump valves, or the main steam isolation valves.

NRC Concern No. 6:
~FP L ~
Are the control cables for the "C" auxiliary,feedwater pump separated from the "A" and 'B" pumps such that they meet the requirements of Appendix R, III.G.2?
The control cables for the auxiliary feedwater pumps meet the requirements of Appendix R, lll.G.2.
Is the loss of pressurizer heaters precluded or emergency procedures prepared for the appropriate operator action?
Loss-of pressurizer heaters is an event that the plant operators are trained and qualified for.
Emergency procedures are not prepared for specific equipment
- failures, such as loss of pressurizer heaters.
Is sufficent manpRowei available to fight a fire and safety shutdown the plant?
The Draft procedure submitted in our Alternate Shutdown submittal (FPL letter L-83-5 I 4 dated October 7,
I 983) indicated that personnel are available simultaneously to man the 5 man fire brigade and accomplish alternate shutdown.
NRC Concern No. 7:
~FPL R Regarding associated
- circuits, is circuit coordination an on-going program?
Circuit breaker and fuse coordination is a
generic design consideration for all plant modifications that affect electrical equipment or circuits.
