Dear Mr. Varga:
Re: Turkey Point Units 3 & 4 Docket Nos. 50-250 & 50-25 I Inadequate Core Cooling Instrumentation (ICCI) System NUREG-0737, Item II.F.2 NRC TAC Nos. 45I76 & 45177 The attached information is submitted in response to your December l4, l984 letter which requested that FPL provide an updated status of the Turkey Point Units 3 & 4 ICCI implementation.
This information supplements that included in our September 28, I 984 letter to you.
Should you or your staff have any questions regarding this information, please call USe Yours very truly, 6 %.PaW~Q.

Turkey Point Units 3 end 4 Inadequate Core Cooling Instrumentation (ICCI) System Implementation The following updates or supplements the information included in FPL's September 20, l984 submittal (L-84-239) regarding ICCI Implementation.
Installation of the interconnecting cable from QSPDS to SAS will be made in conjunction with SPDS implementation scheduled to be completed during the upcoming refueling outages for Turkey Point Units 3 and 4.
2.
The Ml cable/connector qualification test reports were received from Combustion Engineering on November 30, 1984 and are now being reviewed by FPL and Bechtel.
3.
The following plant emergency operating and offnormal operating procedures have been revised to reflect the ICCS system installation.
The revisions are consistent with the technical content of the NRC approved Westinghouse Owners Group Emergency
Response
Guidelines.
Issue of the procedures and implementation has been delayed due to the large number of other procedures currently being revised by the plant staff.
Implementation of these procedures is now expected to be completed by January 25, l985.

(2) to FPL -letter L-84-239 dated September 20,
- 1984, the procedure walk-throughs to complete the task analysis portion of the ICCI System design will be done as part of the Task Analysis Upgrade Program (Detailed Control Room Design Review) and coordinated with the development and implementation of the procedures based on the approved Westinghouse Emergency
Response
Guidelines, which are scheduled to be completed by December 3I, l985. Specific task analyses
0 U
using the interim EOP's and ONOP's referred to above will not be done.
Problems identified during their implementation will be resolved on a case by case basis.
A systems function review and task analysis which included inadequate core cooling event sequences was performed as part of the Turkey Point Plant Units 3
and 4 Detailed Control Room Design Review and discussed in the Summary Report submitted to the NRC on November I, l983 (FPL letter L-83-547).
5.
The hardware and software problems discussed during the audit are scheduled to be resolved by the end of the next refueling outage for each unit.
6.
Proposed technical specifications for the ICCI System will be submitted by March l5, l985.
They will be based on the guidance provided in Generic Letter 83-37, the additional guidance in the December l4, l984 NRC letter, and technical specifications for ICCI recently issued by the NRC.
