Dear Mr. Eisenhut:
RE:
St. Lucie Unit ~No.
1 I
Docket No. 50-335 Fire Protection Alternative Shutdown Report 10 CFR 50 A endix R Section III.L Pursuant to the requirement of 10 CFR 50 Appendix R Section III.G.3, Florida Power and Light herewith submits the Alternative Shutdown Report for St. Lucie Unit 1.
Alternate shutdown capability is being provided in accordance with the requirements set forth in Appendix R Section III.L for a fire in either the Control Room or the Cable Spread Room.
Alternate shutdown will be accomplished through the use of the Hot Standby Panel (HSP) which is capable of maintaining the unit at hot standby.
To achieve and maintain cold shutdown, local manual actions will be coordinated by the HSP operator.
If additional information is required, please contact us accordingly.
Very truly yours, Robert E. Uhrig Vice President Advanced Systems and Technology REU/GJK/mp Attachment cc:

1 ALTERNATIVE SHUTDOWN Since the separation defined in Appendix "R"Section III.G.2 cannot be provided for essential components and circuits in the Control and Cable Spread Rooms, alternative shutdown capabi1ity is provided.
This insures that in the unlikely event a fire makes the Control Room uninhabitable or renders equipment in either room inoperable, the plant can be safely taken to co1d shutdown from a remote location.
A11 other areas of the plant containing essential equipment comply with Section III.G.2 of Appendix "R".
A description of the alternative shutdown capability provided is given be1ow:
a)
Table 2 lists those systems and the components within those systems which are relied upon to provide alternative shutdown capability.
Employing this equipment, plant operators can maintain the Unit at hot standby conditions from the Hot Standby Panel (HSP) and bring the Unit to co1d shutdown with local manual actions.
A11 equipment is operable fo11owing a loss of offsite power.
(See Table 3 for a complete 1ist of instruments and controls avai1able at the HSP).
1 b)
Alternative shutdown.capability is provided for the Contro1 and Cab1e Spread Rooms which contain control circuits for virtua1'ly al1 essential equipment.
A detailed list of the essential components and cables in these areas can be found in Attachment 2 under Fire Zones 70 and 57 respectively.
Existing components and systems as 1isted in Table 2 will be employed to achieve and maintain cold shutdown in the event of a fire in either of these areas.
Wherever necessary, eIectrica1 components and circuitry required for the operation of the above equipment will be relocated or protected to insure both physical and e1ectrica1 separation from the Control and Cable Spread Rooms.
Physical separation is achieved by means of protective enclosures within or complete relocation from these areas and will meet the requirements of Section III.G.2.
Electrical isolation devices are provided where necessary.
c)
Process and Instrumentation Drawings (P&IDs> for piping and components essential to alternative shutdown are presently contained in the SL-1 FSAR since on1y existing systems are utilized.
The fire zone locations of a>>.
equipment containing breakers and isolation devices are listed
$ n Table 1.
Three examples of Control Wiring Diagrams (CWDs) showing typical isolation devices are presented in Attachment 3.
d)
All new isolation or control switches required for alternative shutdown will be installed in a manner consistent with FSAR design criteria and will not degrade that system.
In general, isolation, switches actuate an alarm in the Control Room when placed in the "isolated" position.

& LIGHT COMPANY ST. LUCIE PLANT - UNIT NO. 1 ALTERNATIVE SHUTDOWN e)
Attachment 1 outlines the basic steps required to bring the plant to cold shutdown from outside the Control Room.
This procedure has been developed to instruct plant operators in the specific tasks required to effect safe shutdown.
f)
The manpower available to perform safe shutdown functions as well as fight fires is described in Attachment 1.
g)
Tests will be performed periodically in accordance with Technical Specification requirements for the remote shutdown system.
h)
Technical Specifications will be prepared to cover all new isolation/
transfer switches added for alternative shutdown.
i)
Only existing components and systems will be employed for alternative shutdown.
As such, verification of system capabilities is not required.
Circuitry modifications will be consistent with existing design criteria.
j)
No credit is taken for repair of damaged cold shutdown equipment.
