SUBJECT:

ST. LUCIE PLANT, UNITS 1 AND 2, RE: COMPLETION OF LICENSING ACTION FOR GENERIC LETTER 98-02, "LOSS OF REACTOR COOLANT INVENTORYAND ASSOCIATED POTENTIAL FOR LOSS OF EMERGENCY MITIGATIONFUNCTION WHILE IN A SHUTDOWN CONDITION" (TAC NOS.

MA4808 AND MA4809)

Dear Mr. Plunkett:

On May 28, 1998, the U.S. Nuclear Regulatory Commission (NRC) issued Generic Letter (GL) 98-02, to all holders of operating licenses for Pressurized Water Reactors (PWR), except those who have permanently ceased operations, and have certified that fuel has been permanently removed from the reactor vessel. The NRC issued GL 98-02 to request that PWR licensees evaluate a September 17, 1994, event, which occurred at Wolf Creek, which had the potential to draindown the reactor coolant system (RCS) to the refueling water storage tank and, at the same time, render the emergency core cooling system (ECCS) and residual heat removal (RHR) system inoperable by introducing a steam/water mixture to the suction side of the ECCS and RHR pumps. Addressees of GL 98-02 were requested to provide the following information within 180 days: (1) an assessment of whether the addressee's facility is vulnerable to the September 17, 1994, Wolf Creek event, and (2), if the facility is found to be vulnerable, an assessment of the plant-specific 10 CFR Part 50, Appendix B, quality assurance program attributes which will prevent the subject event. If the addressee's facility was determined to be vulnerable, a response to information item (1) was to be provided pursuant to 10 CFR 50.54(f) and 10 CFR 50.4, and the responses to information items (1) and (2) were to be kept in a licensee's retrievable system for use by the NRC staff on an as-needed basis.

In response to GL 98-02, you provided a letter dated November 22, 1998, for St. Lucie Plant, Units 1 and 2. The submittal indicated that both Units 1 and 2, were vulnerable to the type of incident which occurred at'Wolf Creek and further indicated that the plant evaluation concerning the subject vulnerability (information item (2) of GL 98-02), was being kept in a retrievable licensee system that the NRC can verify on an as-needed or sample basis, in accordance with GL 98-02.

By letter dated December 13, 1999, the Region II NRC staff issued NRC Inspection Report No. 50-335/99-07; 50-389/99-07. The subject inspection report contained details of the NRC staff's on-site verification of activities which you undertook in response to GL 98-02 for

~8j/II; Pig ll'$ ilk~ ll;IllfF' St. Lucie, Units 1 and 2. Specifically, the inspector verified that,S(.,Luciethyg.effectively,~.

t(

% )

T. F. Plunkett implemented administrative controls and operating procedures to preclude an inadvertent drain down event as described in GL 98-02. Operator Training Lesson Plan 0802208, Outage Tasks and Outage Related Events, was revised to include a review of GL 98-02 and the drain down flow paths that had been identified for each unit. Training was provided to the operators using the revised lesson plan to understand the susceptible flow paths, and the administrative and operational controls in place to minimize the potential for human factor contributors to the initiation of a drain down event. The above measures were found by the inspector to be appropriate.

The NRC staff has reviewed your response to GL 98-02 and has concluded that (1) all the information requested by GL 98-02 has been provided, and (2) that your on-site activities adequately addressed the concerns of GL 98-02 for St. Lucie, Units 1 and 2; therefore, we consider GL 98-02 to be closed for St. Lucie, Units 1 and 2.

Request for Additional Information cc w/encl: See next page

e REQUEST FOR ADDITIONALINFORMATION RELATED TO THE AMENDMENTOF THE TECHNICAL SPECIFICATIONS FOR THE EMERGENCY DIESEL GENERATORS ST.'UCIE UNITS 1 AND 2 FLORIDA POWER AND LIGHT COMPANY DOCKET NOS. 50-335 AND 50-389 The staff is concerned over your use of "trigger values" to ensure that the emergency diesel generator (EDG) reliability for St. Lucie Units 1 and 2 remains greater than or equal to the target reliability chosen for your EDGs to meet station blackout (SBO) rule.

Please justify your amendment request without relying on the "trigger values."

Your staff indicated in a telephone conference on January 19, 2000, that each of the Unit 1 and Unit 2 EDGs is capable of powering its dedicated division of safety loads in addition to the complement of selected Unit 1 or Unit 2 toads necessary to maintain the units in Hot Standby through the duration of the SBO event. Your staff also indicated that procedures are in place to accomplish the above throng) the SBO crosstie. Please clarify this aspect of the design for Unit 2 in your application.. In addition, indicate that the time it takes to establish this connection satisfies the availability requirements of an alternate AC source used for the SBO event.

I Page 8, Table 4 - Explain the relationship among the early containment failure probability (0.01 or 0.1), core damage frequency (CDF), and large early release frequency (LERF) ~

Pages 6, 7 and 8, Tables 1, 2 and 3- In Tables 1 and 2, 1.39E-5/yr was referred to as a conditional CDF based on zero EDG unavailability. The same value was referred to as an average baseline CDF in Table 3. Explain.

5. The staff finds that the loss of grid initiating event frequency does not include plant-centered loss of offsite power (LOOP). Does the FPL's risk evaluation include the risk impact of the proposed change due to this plant-centered LOOP initiating event?

Explain.

Is the crosstie recovery event failure probability (0.1) identical for both units? Explain why the asymmetry in design between the units was not captured.

7. Explain how the. recommended Tier 2 restriction is going to be implemented.
8. Explain EOP-99, Appendix G for manual C auxiliary feedwater pump start, and justify the basic event failure probability used for it in your PRA.

SUBJECT:

ST. LUCIE PLANT, UNITS 1 AND 2 - PAST AND FUTURE COMPLIANCE WITH 10 CFR 50.71(e)(4) FOR REVISIONS TO THE UFSAR t

(TAC NOS. M72478 AND M72479)

Dear Mr. Plunkett:

The purpose of this letter is to clarify any misunderstanding of th'e U.S. Nuclear Regulatory Commission (NRC's) regulations that relate to Title 10 of the Code of Federal Regulafions (10 CFR), Subsection 50.71(e)(4). Subsection 50.71(e)(4) specifies the schedular requirements whereby licensees are to submit revisions to their Final Safety Analysis Reports (FSARs). It requires revisions to be made, "... annually or 6 months after each refueling outage provided the interval between successive updates does not exceed 24 months."

In a 1997 survey of licensees, we found numerous cases of noncompliance with this schedular requirement, in both single- and multi-unit sites. A common example of this noncompliance was a multi-unit site that based their submission schedule for all units on the schedule of one of the units.

We understand that an NRC letter to Commonwealth Edison Company (ComEd), dated June 15, 1993, may have caused some confusion about the proper interpretation of the regulation. The letter endorsed an alternative submission schedule proposed by ComEd.

Neither ComEd's proposed schedule, nor the staff's endorsement, were in compliance with the regulation. Nevertheless, many licensees adopted the staff position expressed in the June 15~ letter and deviated from the schedular requirements of the regulation. In order to correct the error, the staff recently granted exemptions to the ComEd plants. The transmittal letter to the exemption (D. Skay to O. D. Kingsley, dated July 27, 1999), states, "this [Skay]

letter and the enclosed exemptions supersede our letter of June 15, 1993."

We note that you have not requested a schedular exemption to Subsection 50.71(e)(4) for St.

Lucie plant. This indicates that you intend to comply with the literal interpretation of the regulation, regardless of how you have interpreted the regulation in the past. We will exercise enforcement discretion, in accordance with Section VII.B.6 of the NRC Enforcement Policy, for past violation(s) of Subsection 50.71(e)(4). In the future, we will enforce the schedular requirements as prescribed, or as modified by an exemption.
