3/4.5 EMERGENCY RE COOLING SYSTEMS ECCS

~ ill 3/4.5.1 SAFETY INJECTION TANKS I

The OPERABILITYof each of the RCS safety injection tanks ensures that a sufficient volume of borated water will be immediately forced into the reactor core through each of the cold legs in the event the RCS pressure falls below the pressure of the safety injection tanks. This initial surge of water into the core provides the initial cooling mechanism during large RCS pipe ruptures.

The limits on safety injection tank volume, boron concentration and pressure ensure that the assumptions used for safety injection tank injection in the accident analysis are met.

The limit of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for operation with an SIT that is inoperable due to boron concentration not within limits, or due to the inability to verify liquid volume or cover-pressure, considers that the volume of the SIT is still available for injection in the event of a LOCA. If one SIT is inoperable for other reasons, the SIT may be unable to perform its safety function and, based on probability risk assessment, operation in this condition is limited to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

3/4.5.2 and 3/4.5.3 ECCS SUBSYSTEMS The OPERABILITYof two separate and independent ECCS subsystems ensures that sufficient emergency core cooling capability will be available in the event of a LOCA assuming the loss of one subsystem through any single failure consideration. Either subsystem operating in conjunction with the safety injection tanks is capable of supplying sufficient core cooling to limit the peak cladding temperatures within acceptable limits for all postulated break sizes ranging from the double ended break of the largest RCS cold leg pipe downward. In addition, each ECCS subsystem provides long term core cooling capability in the recirculation mode during the accident recovery period.

The Surveillance Requirements provided to ensure OPERABILITYof each component ensure that at a minimum, the assumptions used in the accident analyses are met and that subsystem

'PERABILITYis maintained.

The limitations on HPSI pump operability when the RCS temperature is z 270'F and z 236'F, and the associated Surveillance Requirements provide additional administrative assurance that the pressure/temperature limits (Figures 3.4-2a and 3.4-2b) will not be exceeded during a mass addition transient mitigated by a single PORV. A limit on the maximum number of operable HPSI pumps is not necessary when the pressurizer manway cover or the reactor vessel head is removed.

TS 3.5.2, ACTION a.1. provides an allowed outage/action completion time (AOT) of up to 7 days from initial discovery of failure to meet the LCO provided the affected ECCS subsystem Is inoperable

,'nly because its associated LPSI train is inoperable. This 7 day AOT is based on the findings of a

, deterministic and probabilistlc safety analysis and is referred to as a "risk-informed" AOT extension.

Entry into this ACTION requires that a risk assessment be performed in accordance with the

'Configuration Risk Management Program (CRMP) which is described in the Administrative I Procedure (ADM-17.08) that implements the Maintenance Rule pursuant to 10 CFR 50.65.

EMERGENC RE COOLING SYSTEMS ECCS 3/4.5.1 SAFETY INJECTION TANKS

'he OPERABILITYof each of the Reactor Coolant System (RCS) safety injection tanks ensures that a sufficient volume of borated water will be immediately forced into the reactor core through each of the cold legs in the event the RCS pressure falls below the pressure of the safety injection tanks.

This initial surge of water into the core provides the initial cooling mechanism during large RCS pipe ruptures.

The limits on safety injection tank volume, boron concentration, and pressure ensure that the assumptions used for safety injection tank injection in the safety analysis are met.

The safety injection tank power-operated isolation valves are considered to be "operating bypasses" in the context of IEEE Std. 279-1971, which requires that bypasses of a protective function be removed automatically whenever permissive conditions are not met. In addition, as these safety injection tank isolation valves fail to meet single failure criteria, removal of power to the valves is required.

C St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2000-57 Attachment Page 1 FPL Comments on LPSI AOT Extension Staff Safety Evaluation St. Lucie Unit 1 and Unit 2 License Amendments 164 and 106 Dated February 15, 2000 SE Section 4.1:

"The primary role of the low pressure safety injection (LPSI) system during power operation is to contribute to the mitigation of a large loss of coolant accident (LOCA). The postulated frequency of a large LOCA event is on the order of 10 per year. In contrast, during Modes 5 and 6, the operability of at least one LPSI train operating in the shutdown cooling mode is required at all times for reactor coolant system (RCS) heat removal. Thus, in the broad view, performing preventive and corrective maintenance at power on the LPSI system can contribute to an overall enhancement of plant safety by increasing the availability of at least one LPSI train for shutdown cooling (SDC) when it is needed in Modes 5 and 6."

FPL Comment 1 Staff states the large LOCA frequency is on the order of E-4lyr. The proposed license amendment (PLA) states "on the order ofE-5lyr. " (see below)

Staff says SDC in Modes 5 and 6, PLA stated "Modes 4, 5, and 6. " (see below)

A licable FPL PLA section 3.2 "In the upper operating modes, LPSI trains must be available in the event that LOCA mitigation becomes necessary. The estimatedPequency of a large LOCA is on the order of E-05 per year. The LPSI system would also be used for RCS heat removal in the event of a SGTR or other non-LOCA design basis events, which have estimatedPequencies on the order of E-03 per year and lower. In contrast, at least one LPSI train is required to be operable for RCS heat removal during normal shutdown operations in Modes 4, 5, and 6, and is almost always in operation when in these modes. Therefore, in the broad view, performing preventive and corrective maintenance on LPSI trains when at power can enhance overall plant safety by increasing the availability and reliability of the LPSI system for normal shutdown-cooling operations, i.e., when it is most often needed. "

SE section 4.2 first ara ra h "The two trains of the LPSI system, in combination with the two trains of the high pressure safety injection (HPSI) system, form two redundant ECCS trains. The two LPSI pumps are high volume, low head centrifugal pumps designed to supplement the SIT inventory in reflooding the reactor vessel to ensure core cooling during the early stages of a large break LOCA. The LPSI pumps take suction from the refueling water storage tank (RWST),

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2000-57 Attachment Page 2 during the injection phase of a LOCA event, and pump the water through a common discharge header. Once inside containment, the LPSI headers combine with HPSI and SIT discharge piping, and flow is directed through independent injection headers into each of the four reactor coolant system (RCS) cold legs and into the reactor vessel. The LPSI system pumps start and valves open upon receipt of a safety injection actuation signal. When the RWST level is drawn down by inventory transfer during the injection phase, a low RWST level actuates a recirculation actuation signal which stops the LPSI pumps. This step is necessary to ensure adequate net positive suction head remains available for the HPSI pumps and the containment spray pumps. By design, post-LOCA long term core cooling is supplied by the HPSI pumps and containment spray pumps taking suction from the containment sump."

FPL Comment 2 Staff refers to "RWST" and the PLA refers to the "RWT. " (See below)

Staff states "LPSI injects through a common header. " This is not correct for Unit 2. The PLA describes the difference between Unit 1 and Unit 2. (See below).

A licable FPL PLA section 2.1 "Each LPSI train contains a high volume, low head, centrifitgal pump designed to supplement the Safety Inj ection Tank (SIT) inventory in re flooding the reactor vessel with borared water during the early stages ofa large break loss ofcoolant accident (LOCA). Tlte LPSI system is actuated by an automatic or manually initiated Safety Injection Actuation Signal (SIAS) which starts the associated pump and causes the LPSI flow control valves to open. The LPSI pumps transfer borated waterPom the Refu ehng Water Tattk (RWT) through the LPSI header(s), and into the safety injection penetrations to the Reactor Coolant System (RCS) cold legs. During the recircularion phase of the LOCA scenario, the LPSI pumps are stopped by an automaric or manually initiated Recirculation Actuation Signal (RAS) and long tenn core cooling is supplied by the HPSI pumps taJd ng suctionjom the containment sump. The LPSI systems for both St. Lucie units are functionally the same, but contain differences in the piping arrangement, e.g., PSL1 lls u common LPSI header which branches out to each of the four high pressure cold leg penetrattons whereas PSL2 has t>vo independent LPSI headers, each branching out to two of the high pressure cold leg penetrations. "

SEsection4.2third ara ra h "In the event that one LPSI train is out of service and the second LPSI train fails, the operator can continue to control the plant during an SGTR event by drawing steam off of the unaffected steam generator. Even though loss of both LPSI trains is beyond the design basis accident assumptions, this cooling mechanism can be maintained indefinitely, provided condensate is available to the unaffected steam generator. Without considering condensate storage tank replenishment, St. Lucie, Units 1 and 2, have a sufficient inventory to steam the

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2000-57 Attachment Page 3 unaffected steam generator for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. St. Lucie; Units 1 and 2, also have the ability to realign the containment spray pumps to provide RCS SDC capability. Therefore, having one LPSI train out of service should not affect the licensee's ability to mitigate an SGTR event, including conditions beyond design basis."

FPL Comment 3 Both units do not have sufhcient condensate inventory to steam for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> without makeup.

Unit 2 has sufhcient volume, but Unit 1 does not. (See below) licable FPL PLA section 3.2.1 "Table 6.2.1-1 of CE NPSD-995 provides a comparison of secondary side heat removal capabilities for CEOG plants, and includes the approximate condensate storage depletion time (without refill). The minimum contained volume of condensate required by the PSL1 and PSL2 TS is 116,000 gallons and 307,000 gallons, respectively. However, the steaIn generator heat sink can be maintained indefinitely provided make-up condensate remains available to the Condensate Storage Tank (CST). Plant procedures provide instructions for replenishing condensate inventory storage, and also include instructions for supplying the PSL1 Auxiliary Feedwater Pumps from the PSL2-CST in the event that the smaller PSL1-CST becomes unavailable. Extending the LPSI AOT would not impact this defense-in-depth capability. "

FP Position Su orted b SE section 4.3.3:

The licensee re-evaluated all ogsite power recovery cases for both St. Lucie units. One case was added to the Unit 1 analysis for recovery of offsite power in 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> (approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> before the Unit 1 condensate storage tank (CST) would deplete without condensate replenishment).

SE section 4.3.2 "The LPSI preventive and corrective maintenance (staff-estimated) weighted average single AOT risks for St. Lucie, Units 1 and 2, are 8.74E-08 for Unit 1 and 8.36E-08 for Unit 2, and are less than the acceptance guideline value 5.0E-07 from Regulatory Guide (RG) 1.177. In addition, the change in the St. Lucie, Units 1 and 2, updated baseline core damage frequency (CDF) (as reported in the CEOG Joint Application Report) due to the LPSI AOT change is about 3%, i.e., from 2.14E-05 per year for Unit 1 and 2.35E-05 per year for Unit 2 to 2.2E-05 per year for Unit 1 and 2.4E-05 per year for Unit 2. The change in CDF of 6E-07 per year for Unit 1 and 5E-07 per year for Unit 2 is within the acceptance guidelines published in RG 1.174. The staff-estimated weighted average incremental conditional large early release probabilities (ICLERPs) are 2.12E-09 for Unit 1 and 1.46E-09 for Unit 2, assuming a baseline early containment failure probability (ECFP) of 0.01.

P

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2000-57 Attachment Page 4 Corresponding ICLERPs for an ECFP of 0.1 are 9.95E-09 for Unit 1 and 8.95E-09 for Unit 2.

All of these ICLERP values are within the RG 1.177 guideline of 5.0E-08."

FPL Comment 4 The Stag references risk assessment results provided in the original CEOG,Joint Applications report but stateslimplies these are based on the St. Lucie updated baseline CDF. As discussed in the PLA (see below), the input to the CEOG report was based on the Internal Plant Events (IPE) results and the PLA results are based on updated models. The Staff in section 4.3.3, however, repeats the PLA words regarding use of the IPE for the CEOG report and updated models for the PLA.

A licable FPL PLA section 3.2.2 "The considerations, assumptions, methodologies, and detailed results of the initial risk assessment are reported in CE NPSD-995, Joint Applications Report for Low Pressure Safety Injection System AOT Extension, Final Report CEOG Task 836, prepared for the CE Owners Group, May 1995, as supplemented by the associated RAI response dated May 31, 1996 (CEOG Letter 96-254, D.F. Pilmer to C.I. Grimes, Chief, Technical Speciftcations Branch, NRR, Project No. 692; June 14, 1996).

FPL Comment 6 The intent of the CRMP as committed to in the PLA is NOT to implement 10 CFR 50.65(a)(4) of the maintenance rule but to implement 10 CFR 50.65(a)(3) of the maintenance rule (see below). RG 1.177, which provides the requirements of the CRMP, also states that the intent is to implement 10 CFR 50.65(a)(3). 10 CFR 50.6S(a)(4) is NOT in effect yet, therefore FPL DOES NOT know the final scope, and thus FPL has NOT committed to it at this rime.

Florida Power & Light Company (FPL) requested, pursuant to Section 2.4.3 of Attachment 1 of NRC Office Letter 803, Guidance for Processing License Wnendments, a sixty day implementation period for these amendments. As permitted by Office Letter 803, FPL notified the NRC Project Manger and Back-up Project Manager informally, via electronic mail, of the requested implementation period on November 30, 1999. Effective December 1,"1999, the NRC changed the St. Lucie Project Manager and FPL's request was lost in the transition.

Please revise the implementation period for these license amendments to sixty days from the date of receipt. This is the first risk-informed license amendment increasing the allowed outage time.

The changes modify the Technical Specifications to extend the allowed outage time (AOT) for a single low pressure safety injection (LPSI) train from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 7 days. As part of the amendment approval, FPL committed to implement a Configuration Risk Management Program (CRMP) that puts a procedure-based probabilistic risk assessment process in place that ensures FPL assesses the overall impact of plant maintenance on plant risk. FPL needs the additional time to implement the license amendment to allow time to, finalize the CRMP and train the station personnel in its use.

In the future, FPL requests that all license amendments for St. Lucie Units 1 and 2 be issued with a standard implementation period of sixty days from receipt. FPL will notify the NRC ifa longer implementation period is required for a specific license amendment. Please contact us ifthere are any questions.

St: Lucie Units 1 and 2 L-2000-002 Docket No. 50-335 and 50-389 Attachment 1 Proposed License Amendment Page2of6 Accident Monitoring Instrumentation And MOV Thermal Overload Bypass EVALUATIONOF PROPOSED TS CHANGES Introduction Florida Power and Light Company (FPL) requests to amend Facility Operating Licenses DPR7 for St. Lucie Unit 1 and NPF-16 for St. Lucie Unit 2 by incorporating the attached Technical Specifications (TS) revisions. The proposed amendments are associated with:

~ the accident monitoring instrumentation TS for both Units 1 and 2,

~ the motor operated valve (MOV) thermal overload protection bypass device TS for Unit 2, and

~ an administrative change to the Unit 2 TS Index.

Background/Discussion Unit 1 Accident Monitorin Instrumentation FPL discovered an apparent discrepancy in the processing of Unit 1 license amendment number 37. Along with other changes based on the NRC's "Category A" TMI related lessons learned recommendations, St. Lucie Unit 1 license amendment number 37 incorporated new Technical Specification requirements for accident monitoring instrumentation (TS 3/4.3.3.8 and Table 3.3-11). ACTION statement 1 states:

"With the number of OPERABLE channels less than required by Table 3.3-11, either restore the inoperable channel(s) to OPERABLE status within 30 days or be in HOT STANDBY within the next $ 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />."

Table 3.3-11 has two columns that describe the number of instrument channels used to monitor specific accident parameters; one column is for the TOTAL NO. OF CHANNELS, and the other column is for the MINIMUMCHANNELS OPERABLE. As the TS is written, it is not clear if the ACTION statement applies to the TOTAL NO. OF CHANNELS or the MINIMUMCHANNELS OPERABLE column.

FPL concluded that an apparent error was made during review, approval, and implementation of the proposed TS changes that were approved by amendment 37. FPL submitted letter L-80-367, dated October 31, 1980, with proposed wording for TS 3.3.3.8 that included two ACTION statements. A 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> ACTION Statement 3.3.3.8.a was proposed that applied when the number of operable channels was less than the MINIMUM CHANNELS OPERABLE requirements of Table 3.3-11. A 30 day ACTION Statement 1 for Table 3.3-11 was proposed that applied when the number of operable channels is less than that specified in the TOTAL NO. OF CHANNELS column. As approved, Unit 1 TS

.St: Lucie Units 1and 2 L-2000-002 Docket No. 50-335 and 50-389 Attachment 1 Proposed License Amendment Page 3 of 6 Accident Monitoring Instrumentation And MOV Thermal Overload Bypass amendment 37 incorporated ACTION 1 of Table 3.3-11, but inexplicably omitted the 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> ACTION Statement requirement contained in TS 3.3.3.8.a. Unit 1 Technical SpeciTication 3.3.3.8, "Accident Monitoring Instrumentation," is not conservative in that it does not contain a more restrictive ACTION statement when the number of operable channels is less than the minimum channels operable requirements. Additionally, the originally proposed allowed outage time (AOT) for the auxiliary feedwater flow (AFW) instrumentation was more restrictive than the AOT for an out of service AFW pump. This proposed license amendment (PLA) will add appropriate ACTION statements that apply when the number of operable instrument channels is less than the minimum channels operable.

Unit 2 Accident Monitorin Instrumentation The St. Lucie Unit 2 TS Table 3.3-10, "Accident Monitoring Instrumentation," erroneously indicates the narrow range reactor coolant outlet temperature Th,i instrumentation is used to satisfy TS accident monitoring requirements. The TS bases indicates that the intent of this TS table is to provide a post accident instrumentation capability that is consistent with the requirements of Regulatory Guide 1.97. In response to the post TMI NUREGs and Regulatory Guide 1.97, separate wide range reactor coolant outlet temperature Th,i instrumentation was installed prior to issuance of the St. Lucie Unit 2 operating license.

However, TS Table 3.3-10 was not revised to reflect the use of wide range Th,i instrumentation. This PLA will correct the Th,i instrumentation error in Table 3.3-10.

Unit 2 Electrical MOV Thermal Overload Protection B ass Devices Unit 2 TS Surveillance 4.8.4 requires the periodic surveillance of the thermal overload protection bypass devices associated with the list of MOVs provided in TS Table 3.8-1.

This TS table includes valves MV-21-4A and MV-21-4B, which were modified via plant modification (PC/M) 268-292 such that they no longer perform a safety function and are no longer MOVs.

PC/M 268-292 included a 10 CFR 50.59 safety evaluation. This PC/M evaluated the relocation and de-energization of MV-21-4A and 4B and concluded these changes did not represent an Unreviewed Safety Question per 10 CFR 50.59. The PC/M also considered the modification's effect on the Technical Specifications and erroneously concluded that "The subject modification does not affect or impact the Technical Specifications." TS Table 3.8-1 should have been identified as requiring revision to delete MV-21-4A and 4B.

This PLA will delete the subject valves from TS Table 3.8-1.

, St Lucie Units 1 and 2 L-2000-002 Docket No. 50-335 and 50-389 Attachment 1 Proposed License Amendment Page 4 of 6 Accident Monitoring Instrumentation And MOV Thermal Overload Bypass Proposed Changes: Description and Bases/Justification The affected TS pages, marked up to show the proposed changes, are included in Attachment 3 for Unit 1 and Attachment 4 for Unit 2.

Descri tion and Bases/Justification of Pro osed Chan es Unit 1 TS Table 3.3-11 For Unit 1 TS Table 3.3-11, add ACTION 6 which reads as follows:

"ACTION 6 With the number of OPERABLE accident monitoring channels less than the Minimum Channels OPERABLE requirements of Table 3.3-11, either restore the inoperable channel(s) to OPERABLE status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or be in at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />."

This action statement will be applicable to the following instrumentation listed in Table 3.3-11: Pressurizer Water Level, RCS Subcooling Margin Monitor, Incore Thermocouples, and Containment Pressure.

The basis and justification for this change is that the addition of the proposed action statement is more conservative than the existing TS and is consistent with the AOT and ACTION statements originally proposed by FPL in letter L-80-367 dated October 31, 1980.

For Unit 1 TS Table 3.3-11, add ACTION 7 that applies to the AFW flow rate instrumentation which reads as follows:

"ACTION 7 With the number of OPERABLE accident monitoring channels less than. the Minimum Channels OPERABLE requirements of Table 3.3-11, either restore the inoperable channel(s) to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />."

The basis and justification for this change is that the AOT is consistent with the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> AOT for an inoperable AFW pump in accordance with the ACTION statement for TS 3.7.1.2 which reads as follows:

"With one auxiliary feedwater pump inoperable, restore at least three auxiliary feedwater pumps (two motor driven pumps and one capable of being powered by an OPERABLE steam supply system) to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />."

This change is necessary to ensure that the AOT for AFW flow rate instrumentation is not more conservative than the AOT for the AFW pump itself.

, Sit. Lucie Units 1 and 2 L-2000-002 Docket No. 50-335 and 50-389 Attachment 1 Proposed License Amendment Page 5 of 6 Accident Monitoring Instrumentation And MOV Thermal Overload Bypass For TS Table 3.3-11, revise ACTION 1 to read as follows:

"ACTION 1 With the number of OPERABLE accident monitoring channels less than the Total No. of Channels shown in Table 3.3-11..."

The basis and justification for this change is that it clarifies that ACTION 1 applies when the number of operable channels is less than the Total No. of Channels column in Table 3.3-11.

Unit 2 TS Table 3.3-10 For Unit 2 TS Table 3.3-10 revise item 2 of the INSTRUMENT column to read:

"Reactor Coolant Outlet Temperature Ti~ (Wide Range)"

The basis and justification for this change is that the wide range reactor coolant outlet temperature instrumentation was installed prior to issuance of the St. Lucie Unit 2 license in order to meet the requirements of Regulatory Guide 1.97. The design 'perating of these instruments is consistent with their use during post accident conditions (e.g.,

environmental qualification, Class 1E safety related power requirements, etc.). The FPL final response to Regulatory Guide 1.97 (L-85-417) credited the use of the wide range reactor coolant outlet temperature instrumentation to meet Regulatory Guide 1.97 requirements. However, TS Table 3.3-10 was not revised to incorporate this design change made in response to Regulatory Guide 1.97. Therefore, this change is acceptable.

Unit 2 Table 3.8-1 Delete valves MV-21-4A and MV-21-4B.

The bases and justification for this change are as follows. Valves MV-21-4A and MV 4B provide isolation of the lube water supply lines to the circulating water (CW) pumps.

Prior to the plant modification performed under PC/M 268-292, the CW pump lube water supply consisted of one tap off of each intake cooling water (ICW) essential (safety related) header. As such, MV-21-4A and 4B used to perform a safety function by isolating the non-safety CW pump lube water from the safety related ICW system upon receipt of a safety injection actuation signal (SIAS). As a result of the plant modification, the CW pump lube water supply was relocated to the non-essential header of the ICW system, commonly referred to as the turbine cooling water (TCW) header, and MV-21-4A and 4B were de-energized, effectively becoming manual valves.

The non-safety TCW header is automatically isolated from the safety related ICW headers via MV-21-2 and MV-21-3 (these valves are listed in Table 3.8-1), which automatically

,- St. Lucie Units 1 and 2 L-2000-002 Docket No. 50-335 and 50-389 Attachment 1 Proposed License Amendment Page6of6 Accident Monitoring Instrumentation And MOV Thermal Overload Bypass close on SIAS. As such, MV-21-4A and 4B no longer perform a safety function and are not required to close upon SIAS. Therefore, this change to Table 3.8-1 is acceptable.

Unit 2 TS Index When the smooth pages were developed for the Reload Process Improvement proposed license amendment submitted by FPL via letter L-98-308, dated December 18, 1998, the reformatted text carried over onto a new page. Page XIX of the Unit 2 TS was not changed to reflect the new pagination. This change is administrative and required to correct a typographical error in the Unit 2 TS Index.

Environmental Consideration The proposed license amendment changes requirements with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.

The proposed amendment involves no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite, and no significant increase in individual or cumulative occupational radiation exposure. FPL has concluded that the proposed amendment involves no significant hazards consideration and meets the criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and that, pursuant to 10 CFR 51.22(b), an environmental impact statement or environmental assessment need not be prepared in connection with issuance of the amendment.

Conclusion FPL determined that these proposed license amendments are necessary to correct existing errors in the Technical Specifications.

St. Lucie Unit 2 utilizes wide range reactor coolant outlet temperature Tii instrumentation to meet Regulatory Guide 1.97 accident monitoring requirements.

~ Correct an existing error in Unit 2 TS Table 3.8-1, Motor Operated Valves Thermal Overload Protection Bypass Devices, by deleting valves MV-21-4A and MV-21-4B from the list. These valves were changed to manual valves and no longer perform a safety function.

~ Correct an administrative error in the Unit 2 TS Index.

I Pursuant to 10 CFR 50.92, a determination may be made that a proposed license amendment involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated; (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety. Each standard is discussed as follows.

(1) Operation of the facility in accordance with the proposed amendments would not involve a significant increase in the probability or consequences of an accident previously evaluated.

] Page 3 of 3 Accident Monitoring Instrumentation And MOV Thermal Overload Bypass The addition of the new ACTION statements for the Unit 1 accident monitoring instrumentation adds conservatism that does not exist in the current Technical Specifications. These changes are consistent with either FPL's originally proposed license amendment for this instrumentation or consistent with the Technical Specification allowed outage time for the component being monitored (i.e., the auxiliary feedwater pumps). Unit 2 valves MV-21-4A and MV-21-4B were modified to be manually operated valves and no longer perform an accident mitigation function. Unit 2 wide range Tii instrumentation is used to satisfy Regulatory Guide 1.97 accident monitoring requirements.

These Technical Specification changes either correct existing errors or add conservatism to the way the Unit is operated. Based on the above, the physical changes to plant equipment or plant operation would not involve a significant increase in the probability or consequences of an accident previously evaluated.

(2) Operation of the facility in accordance with the proposed amendments would not create the possibility of a new or different kind of accident from any accident previously evaluated.

Accident monitoring instrumentation monitors the process of postulated events, and is not an accident initiator. Unit 2 valves MV-21-4A and MV-21-4B were modified to be manually operated valves and no longer have an active safety function, therefore, these valves are not accident initiators. These Technical Specification changes either correct existing errors or add conservatism to the way the Unit is operated. Based on the above, the physical changes to plant equipment or plant operation would not create the possibility of a new or different kind of accident from any accident previously evaluated.

(3) Operation of the facility in accordance with the proposed amendments would not involve a significant reduction in a margin of safety.

The proposed amendments do not involve a significant reduction in a margin of safety.

FPL determined that these proposed license amendments are necessary to correct existing errors or add conservatism to the way the Unit is operated. As such, the assumptions and conclusions of the accident analyses in the UFSAR remain valid and the associated safety limits will continue to be met.

Based on the above discussion and the supporting Evaluation of Technical Specification changes, FPL has determined that the proposed license amendments involve no significant hazards consideration.

'Docket No. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page2of9 Main Steam and Pressurizer Code Safety Valve Set oint Settin and Set oint Testin Re uirements Introduction Florida Power and Light Company (FPL) requests to amend Facility Operating Licenses DPR-67 for St. Lucie Unit 1 and NPF-16 for St. Lucie Unit 2 by incorporating the attached Technical Specifications (TS) revisions. These proposed license amendments (PLA) will revise the Unit 1 and 2 main steam safety valve (MSSV) and pressurizer code safety valve (PSV) Technical Specifications to be consistent with the Standard Technical Specifications (STS). The STS include a provision for MSSV and PSV setpoint setting and setpoint testing that currently does not exist in the St. Lucie Technical Specifications. Specifically, the STS allow an expanded setpoint surveillance testing acceptance tolerance (i.e.,

beyond ~1%), whereas the existing St. Lucie Technical Specifications do not. Expanding the as-found acceptance limits will allow the test program to accept MSSVs and PSVs whose setpoints are found to be within accident analysis assumptions. The z1% as-left criteria will remain unchanged.

St. Lucie Plant and industry experience with safety valves has shown that valve setpoint drift is a common phenomena whereby, over time, the as-found setting of a safety valve may "drift" beyond the original setting tolerance of ~1%. Both the ASME Code and the Standard Technical Specifications for Combustion Engineering Plants recognize setpoint drift and both allow for expanded as-found acceptance limits. The ASME Code accepts a deviation of up to +3% (the Code does not address a negative tolerance). The Standard Technical Specifications, based in part on the ASME Code, accepts a deviation of up to

+3%.

These PLAs will also revise the applicability of the PSV LCOs to be consistent with the STS. Currently, there is a PSV LCO for Modes 1, 2, and 3 and a second PSV LCO for Modes 4 and 5. The STS format consists of a single PSV LCO, applicable in Modes 1, 2, 3 and Mode 4 with RCS cold leg temperatures above the low temperature overpressure protection (LTOP) limit; below the LTOP temperature limit a separate LTOP LCO is applicable.

Background/Discussion The setpoint tolerance for the MSSVs and the PSVs is currently ~1%. This ~1% band has been used as an acceptance criterion for the periodic lift testing of the valves. Per Technical Specification Surveillance Requirements, MSSVs and PSVs are lift tested in accordance with the Inservice Testing Program, procedure ADM-29.01, "Inservice Testing (IST) Program for Pumps and Valves." This lift testing has historically produced results where one or more of the tested valves lifts at a pressure that is outside the ~1% band.

Although the as-found lift pressure may be bounded by the accident analysis, FPL is required to initiate a licensee event report (LER) as a condition prohibited by the Technical Specifications because they do not explicitly allow for an as-found lift setpoint tolerance.

'ocket No. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page3of9 Main Steam and Pressurizer Code Safety Valve Set oint Settin and Set oint Testin Re uirements St. Lucie Plant and industry experience with safety valves has shown that valve setpoint drift is a common phenomena whereby, over time, the as-found setting of a safety valve may "drift" beyond the original setting tolerance of ~1%. Both the ASME Code, ASME/ANSI OM-1987, "Operation and Maintenance of Nuclear Power Plants, Part 1 Requirements for Inservice Performance Testing of Nuclear Power Plant Pressure Relief Devices," and the Standard Technical Specifications for Combustion Engineering Plants, NUREG-1432, recognize setpoint drift and both allow for expanded as-found acceptance limits. The ASME Code accepts a deviation of up to +3% (the Code does not address a negative tolerance). The Standard Technical Specifications accepts a deviation of up to

+3%.

Description of the Proposed Changes The proposed Technical Specification changes are summarized below. Marked-up Technical Specification pages for this proposed change are provided as Attachments 3 and 4.

Note - This evaluation does not revise the requirement to set the MSSVs and PSVs within a tolerance of ~1% .

MSSVs Technical Specification 3.7.1.1 (both units), Turbine Cycle Safety Valves, requires the MSSVs to be operable with settings in accordance with Table 4.7-1 (Unit 1) and Table 3.7-2 (Unit 2). Both of these tables identify a setpoint tolerance of ~1%. The Bases for Technical Specification 3.7.1.1 (both units) do not discuss setpoint tolerances and/or setpoint drift.

Section 3.7.1 of the STS provides a clear distinction between the tolerance used for setting of the lift setpoint and the tolerance used for surveillance testing of the lift setpoint.

Specifically, Surveillance Requirement 3.7.1.1 states the following:

Verify each required MSSV lift setpoint per Table 3.7.1-2 in accordance with the Inservice Testing Program. Following testing, lift settings shall be within STS Table 3.7.1-2 lists the MSSVs and identifies the lift setting as "psig ~[3]%" (the use of the "[]" parentheses indicates that a plant specific value is to be provided). The Bases for this STS specification states:

Table 3.7.1-2 allows a ~[3%] setpoint tolerance for OPERABILITY; however, the valves are reset to ~1% during the Surveillance to allow for drift.

I St. Lucie Units 1 and 2 L-2000-001

'ocket No. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page4of9 Main Steam and Pressurizer Code Safety Valve Set oint Settin and Set oint Testin Re uirements The proposed changes of Attachments 3 and 4 provide an expanded setpoint tolerance for valve testing that is based on existing plant accident analyses. The Bases of the above MSSV Technical Specifications will be revised to distinguish between the as-found surveillance testing acceptance criteria added by this evaluation and the unchanged as-left setpoint acceptance criteria. Table 4.7-1 (Unit 1) and Table 3.7-2 (Unit 2) will be revised to reflect the as-left setpoint range rather than a specific setpoint value. Although this table format is slightly different than the table format presented in the STS, it will provide consistency with the format of the PSV specification (the STS formats for the PSV and MSSV specifications are inconsistent). The wording of the Action for TS 3.7.1.1 is being revised to change the "Cold Shutdown...30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />" requirement to a "Hot Shutdown...12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />" requirement. This is consistent with the STS and is acceptable since the LCO does not require MSSV operability in Hot Shutdown. Action "b" is retained in lieu of using the STS note regarding Modes 1 and 2 applicability of the Surveillance Requirement.

In addition to the above changes, the MSSV orifice size is being deleted from Table 4.7-1 (Unit 1) and Table 3.7-2 (Unit 2). The orifice size is a design feature that cannot be changed without a formal modification to the valves. The STS do not include valve orifice size requirements.

PSVs Technical Specifications 3.4.2 (Unit 1) and 3.4.2.1 (Unit 2), Reactor Coolant System Safety Valves Shutdown, and Technical Specifications 3.4.3 (Unit 1) and 3.4.2.2 (Unit 2), Safety Valves Operating, require the PSVs to be operable with a lift setting of 2500 psia ~1%.

The Bases for these Technical Specifications do not discuss setpoint tolerances and/or setpoint drift.

Section 3.4.10 of the STS provides a clear distinction between the tolerance used for setting of the lift setpoint and the tolerance used for surveillance testing of the lift setpoint.

Specifically, Surveillance Requirement 3.4.10.1 states the following:

Verify each pressurizer safety valve is OPERABLE in accordance with the Inservice Testing Program. Following testing, lift settings shall be within 1%.

The Bases for this STS specification states:

The pressurizer safety valve setpoint is x[3%] for OPERABILITY; however, the valves are reset to ~1% during the Surveillance to allow for drift.

The proposed changes of Attachments 3 and 4 provide an expanded setpoint tolerance for valve testing that is based on existing plant accident analyses. As such, the referenced Technical Specifications will be revised to note these setpoint tolerances. Also, the wording of the associated LCOs, Actions, Surveillance Requirements, and corresponding Bases will be revised in a manner similar to the STS.

'ocket No. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page 5 of 9 Main Steam and Pressurizer Code Safety Valve Set oint Settin and Set oint Testin Re uirements Note that the STS have a single PSV LCO that is applicable in Modes 1, 2, 3 and Mode 4

>[285]'F. At or below [285]'F a separate LTOP LCO is applicable and the PSVs are no longer required to be operable. The St. Lucie TS currently include two LCOs for RCS overpressure protection in Modes 4 and 5: one LCQ for the PSVs and one LCO for the LTOP system. The St. Lucie TS also include an LCQ for PSV operability in Modes 1, 2, and 3. These proposed license amendments revise the St. Lucie TS to adopt the STS format. This will delete the "overlap" in required RCS overpressure protection.

In addition, the LCOs will be revised to reflect the as-left PSV setpoint acceptance tolerance values in units of psig in lieu of psia. The actual setpoint value of 2500 psia is not being changed. The acceptance tolerance range is calculated based on the setpoint value of 2500 psia, then converted to units of psig. The Bases will be revised to explain the above. This change will make the Technical Specifications consistent with implementing procedures, which use units of psig.

Bases/Justification of the Proposed Changes UFSAR Section 5.2.2.1 of the Unit 1 UFSAR and Section 10.3.2 of the Unit 2 Updated Final Safety Analysis Report (UFSAR) provide similar descriptions of the MSSVs. The MSSVs are described as providing overpressure protection for the shell side of the steam generators and the main steam line piping up to the main steam isolation valves. The MSSVs are ASME Code, spring loaded, open bonnet, flange mounted safety valves that discharge to atmosphere. There are eight MSSVs installed on each main steam header, four of which are set at 985.3 psig (1000 psia) and four of which are set at 1025.3 psig (1040 psia).

Table 5.5-2 (Unit 1) and Table 10.3-1 (Unit 2) provide design information on the MSSVs, including setpoint values. There is no detailed discussion in the UFSARs regarding setpoint testing requirements and/or acceptance limits.

Section 5.5.3 of the Unit 1 UFSAR and Section 5.4.13 of the Unit 2 UFSAR provide similar descriptions of the PSVs. The PSVs are described as providing overpressure protection for the reactor coolant system. The PSVs are ASME Code, spring loaded, enclosed bonnet, flange mounted safety valves that discharge to the quench tank. There are three PSVs installed on top of the pressurizer, each of which is set at 2485.3 psig (2500 psia).

Table 5.5-4 (Unit 1) and Table 5.4-8 (Unit 2) provide design information on the PSVs, including setpoint values. There is no detailed discussion in the UFSARs regarding setpoint testing requirements and/or acceptance limits.

For both the MSSVs and the PSVs, Unit 1 and 2 UFSAR Chapter 15 accident analyses describe, valve actuation assumed at varying pressure values. The values assumed therein are for analysis purposes only and are not intended to represent setpoint requirements. A review of setpoint tolerances with respect to plant accident analyses is provided in the evaluation below.

'ocket No. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page6of9 Main Steam and Pressurizer Code Safety Valve Set oint Settin and Set oint Testln Re uirements Evaluation and Justification of Chan es The Reference 3 Standard Technical Specifications distinguish between the safety valve setpoint tolerance and the tolerance used for surveillance testing of the MSSVs and PSVs.

This distinction is made in the Bases section of the STS. Specifically, the STS describe a

"~[3%] setpoint tolerance for OPERABILITY; however, the valves are reset to ~1% during the Surveillance to allow for drift." Note that the STS refer to testing in accordance with the ASME Code and the ~3% value is likely used in the STS since +3% is the value recognized in the Code (Reference 2) as a tolerance beyond which the valve is considered to have failed its lift test. The Code does not address negative tolerances.

As noted above, MSSV and PSV setpoints are established within a ~1% tolerance; however, as identified in the STS, plant specific tolerances should be provided for determination of operability. The tolerance to be specified for valve operability is logically limited by the ability of each plant's accident analyses to accommodate the tolerance. FPL reviewed the relevant accident analyses to provide the following analysis.

Set oint Tolerances - St. Lucie Unit 1 The safety analysis inputs are documented in SAPP-1, Revision 3, "St. Lucie Unit 1 Safety Analysis Plant Parameters." The safety analysis impacted by the PSV and the MSSV set pressures are:

1) Loss of External Load (LOEL), and
2) Small Break LOCA The analysis for LOEL assumes that openings of safety valves do not occur until the pressure reaches a value corresponding to valve tolerance of +1% for MSSVs and +3% for PSVs (SPC report EMF-96-135, "St. Lucie Unit 1 Chapter 15 Event Review and Analysis for 30% Steam Generator Tube Plugging," May, 1996 and SPC letter TMH:97:210, T.M.

Howe (SPC) to J. Polavarapu (FPL), "Assessment of Change in Calculated Peak Secondary Side Pressure due to Changes in Modeling of St. Lucie Unit 1 MSSVs," July 16, 1997). The negative tolerance for the MSSVs has no adverse effect on this analysis.

For the PSVs, the tolerance on the negative side is limited by the reactor trip, such that the PSVs do not open prior to the trip setpoint. The analysis assumes late opening of the PSVs to maximize the overpressure calculation. The high pressure trip setpoint is 2400 psia with an uncertainty of 22 psi. Since the valve lift setpoint is 2500 psia, a tolerance on the negative side of up to 2.5% will not affect the analysis results, assuming a conservative uncertainty of 37 psi on the trip setpoint.

The analysis for a small break LOCA supports an MSSV setpoint tolerance of +3% (SPC report EMF-1987, "St. Lucie Unit 1 Small Break LOCA Analysis with Asymmetric HPSI Flow," November, 1997 and SPC letter RIW:99:141, R.l. Wescott (SPC) to R.J. Rodriguez (FPL), "Transmittal of Small Break LOCA FSAR Update Package," June 14, 1999). Since

'Docket No. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page 7 of 9 Main Steam and Pressurizer Code Safety Valve Set oint Settin and Set oint Testin Re uirements there is no analytical concern regarding the negative setpoint tolerance for the MSSVs, the STS value of -3% is used.

The following as-found setpoint tolerance limits are therefore acceptable based on the current UFSAR analysis:

MSSVs 1% -3%

PSVs 3% -25%

Set oint Tolerances - St. Lucie Unit 2 The analysis inputs for St. Lucie Unit 2 are documented in SAPP-2, Revision 4, "St. Lucie Unit 2 Safety Analysis Plant Parameters," and the values supported by the analysis, submitted to the NRC as part of Reload Process Improvement (RPI), are presented in ABB letter F2-99-048, G. Singh (ABB-CE) to R. J. Rodriguez (FPL), "Transmittal of St. Lucie Unit 2 Reload Checklist Document, Revision 3," May 24, 1999. Since there is no analytical concern regarding the negative setpoint tolerance for the MSSVs, the STS value of -3% is used. Based on these references, the following values of MSSV and PSV as-found setpoint tolerances are supported by the UFSAR analysis to be incorporated in Cycle 12:

MSSVs +1%, -3%

PSVs 2%

Since the above analysis was performed for Cycle 12 and the plant is currently operating in Cycle 11, a review was performed to determine the applicability of the proposed tolerances for EOC 11 setpoint testing. The review concluded the RPI analysis bounds the conditions at EOC 11; therefore, the setpoint tolerances proposed above remain applicable for the year 2000 refueling outage.

Note that for both the Unit 1 and Unit 2 analyses above, the setpoint tolerances were calculated using the current Technical Specification MSSV and PSV setpoint values in units of psia.

Deletion of MSSV Orifice Size The MSSV orifice size data is being deleted from Table 4.7-1 (Unit 1) and Table 3.7-2 (Unit 2). While it is appropriate for the Technical Specifications to identify safety valve setpoints and to provide surveillance testing to ensure proper valve performance, safety valve orifice size is a passive, fixed design feature that cannot "drift" or otherwise be changed without a formal modification to the valves. There is no existing TS Surveillance associated with this design feature and the STS do not include valve orifice size requirements. As such, it is acceptable to delete this unnecessary detail from the Technical Specifications.

'ocket No. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page 8 of 9 Main Steam and Pressurizer Code Safety Valve Set oint Settin and Set oint Testin Re ulrements PSV LCO Reformattin Unit 1 The original Unit 1 TS, issued in 1976, did not include an LCO specifically for LTOP conditions. RCS overpressure protection was provided solely via TS 3.4.2, for PSV operability in Modes 4 and 5, and TS 3.4.3, for PSV operability in Modes 1, 2, and 3. TS Amendment ¹60, issued in 1983, subsequently added TS 3.4.13 for LTOP, which utilizes the PORVs for RCS overpressure protection whenever cold leg temperatures are below a predetermined limit, which includes operation in Modes 4 (partial), Mode 5 and Mode 6.

Amendment ¹60 did not modify the existing PSV LCOs, thus it created an overlap in the TS required RCS overpressure protection provided by the PSVs and PORVs. At the time Amendment ¹60 was issued it was apparently not recognized that the PSV LCOs should have been revised.

The STS format provides a single LCO for PSV operability and a single LCO for LTOP protection. STS 3 4.10 requires the PSVs to be operable in "MODES 1, 2, and 3, MODE 4 with all RCS cold leg temperatures > [285] 'F. STS 3.4.12 requires the PORVs to be operable for LTOP protection in "MODE 4 when any RCS cold leg temperature is ~ [285]

'F, MODE 5, MODE 6..." The Bases for these specifications describe "[285] 'F" as the RCS cold leg temperature for which, based on plant-specific analysis, LTOP protection is required. The applicability of these two LCOs is such that they provide for continual RCS overpressure protection from Mode 1 through Mode 6 without any overlap between them.

The proposed changes provided in Attachment 3 will combine TS 3.4.2 and 3.4.3 into a single LCO and will eliminate the PSV LCO applicability for Mode 5. Additionally, PSV Mode 4 applicability will be limited to the condition when all RCS cold leg temperatures are greater than 281'F, which is the point at which, during a cooldown, the PORVs are required to be operable for LTOP protection (TS 3 4.13). The cooldown LTOP "ceiling" of 281'F was selected since it is more limiting than the heatup "ceiling" of 304'F.

This change is acceptable since it does not diminish the ability of the Technical Specifications to provide required overpressure protection of the RCS and since it is consistent with the STS format. There is no accident analysis that is affected by this change.

PSV LCO Reformattin Unit 2 With respect to the PSVs and PORVs, the original Unit 2 TS (issued in 1983) were similar to the Unit 1 TS as of Amendment ¹60. Unit 2 TS 3.4.2.1 requires PSV operability in Modes 4 and 5, and TS 3.4.2.2 requires PSV operability in Modes 1, 2 and 3. Additionally, TS 3.4.9.3 requires the PORVs to be operable for RCS overpressure protection whenever cold leg temperatures are below a predetermined limit, which includes operation in Modes 4 (partial), Mode 5, and Mode 6.

The proposed changes to the Unit 2 TS are similar to those described above for Unit 1 and are provided in Attachment 4. The only significant difference between the units is the

The justification for this Unit 2 change is the same as for the Unit 1 change.

Environmental Consideration The proposed license amendments change requirements with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.

The proposed amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite, and no significant increase in individual or cumulative occupational radiation exposure. FPL has concluded that the proposed amendments involve no significant hazards consideration and meets the criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and that, pursuant to 10 CFR 51.22(b), an environmental impact statement or environmental assessment need not be prepared in connection with issuance of the amendments.

Conclusion There is no safety significance associated with the proposed changes. The MSSVs and PSVs will continue to be set to the as-left tolerance of ~1% and will perform as assumed in plant accident analyses. The proposed changes simply clarify that as long as MSSV and PSV as-found lift setpoints are within accident analyses assumptions, the valves may be considered operable. This change allows for a limited amount of setpoint drift and is consistent with the provisions of the Standard Technical Specifications and ASME Code.

The PSV lower mode LCO changes will provide a clear distinction between PSV and PORV/LTOP requirements while ensuring the required RCS overpressure protection is provided.

Converting the PSV setpoint value to units of psig is acceptable since the actual valve lift setpoint and as-left setpoint tolerances are effectively not changing. Applying the as-found acceptance tolerances to the lift setpoint in units of psia and then converting to units of psig is acceptable since it is consistent with the above accident analysis review.

The proposed Technical Specification changes governing MSSV and PSV as-found set pressures are acceptable since they are based on existing accident analyses assumptions and they are consistent with the STS and ASME Code, which allow up to a ~3% tolerance for as-found setpoint testing. The valves will continue to be set within the existing required

+1% setpoint tolerance.

Specifically, the STS allow an expanded setpoint surveillance testing acceptance tolerance (i.e., beyond ~1%),

whereas the existing St. Lucie Technical Specifications do not. There is no safety significance associated with the proposed changes.

Expanding the as-found acceptance limits will allow the test program to accept MSSVs and PSVs whose setpoints are found to be within accident analysis assumptions. The ~1% as-left criteria will remain unchanged. The proposed changes simply clarify that as long as MSSV and PSV as-found lift setpoints are within accident analyses assumptions, the valves may be considered operable. This change allows for a limited amount of setpoint drift and is consistent with the provisions of the Standard Technical Specifications and ASME Code. The PSV lower mode LCO changes will provide a clear distinction between PSV and PORV/LTOP requirements while ensuring the required RCS overpressure protection is provided.

I Pursuant to 10 CFR 50.92, a determination may be made that a proposed license amendment involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated; (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety. Each standard is discussed as follows.

(1) Operation of the facility in accordance with the proposed amendments would not involve a significant increase in the probability or consequences of an accident previously evaluated.

The probability of occurrence of an accident previously evaluated has not been increased. The changes provided in this safety evaluation do not affect the assumptions or results of any accident evaluated in the UFSAR. The actual setpoints and as-left setpoint tolerances of the MSSVs and PSVs are not changed as a result of this evaluation.

Likewise, the consequences of any accident previously evaluated have not been increased. The ability of the MSSVs and PSVs to respond to accident conditions as assumed in any accident analysis has not been affected (i.e., adequate overpressure protection is provided). The proposed changes allow for the acceptance of safety

(2) Operation of the facility in accordance with the proposed amendments would not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed activity does not create the possibility of an accident of a different type than any previously evaluated.'o physical plant changes are being made and no new failure modes have been introduced by the proposed changes. This evaluation revises the acceptance criteria for MSSV and PSV lift test results based on tolerances that are consistent with accident analysis assumptions. The actual setpoints and as-left setpoint tolerances of the MSSVs and PSVs are not changed as a result of this evaluation.

(3) Operation of the facility in accordance with the proposed amendments would not involve a significant reduction in a margin of safety.

El The margin of safety as defined in the basis for any Technical Specification or in any licensing document has not been reduced. MSSV and PSV setpoint values are not being changed. MSSV and PSV setpoints are still required to be set within a tolerance of ~1'/o (the as-left setpoint tolerance). This evaluation allows for the revision of acceptance criteria for MSSV and PSV lift test results such that testing criteria is consistent with accident analysis assumptions. This will allow for the accommodation of setpoint drift without invalidating the accident analyses. The proposed changes are consistent with the Standard Technical Specifications, which require MSSV and PSV setting within a ~1/o tolerance, but allow surveillance testing to accept valves that lift within "~[3]'/0." A review of the plants'ccident analyses has identified the plant-specific tolerances that may be used for this surveillance testing. These values have been used in the Attachment 3 and 4 proposed changes.

Conclusion Based on the above discussion and the supporting Evaluation of Technical Specification changes, FPL has determined that the proposed license amendments involve no signiTicant hazards consideration.

'he plant is designed to operate with both reactor coolant loops and associated reactor coolant ptsnps in operation, and maintain DNBR above the DNBR limit during all normal operations and anticipa .ed transients . In

'MODES 1 and 2 with one reactor coolant loop not in operation, this specifica-tion requires that the plant be in at least HOT STANDBY within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

In MODE 3, a single reactor coolant loop provides sufficient heat removal capability for removing decay heat; however, single failure considerations require that two loops be OPERABLE.

In MODE 4, and in MODE 5 with reactor coolant loops filled, a single reac-tor coolant loop or shu down cooling loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops (either shutdown cooling or RCS) be OPERABLE.

In MODE 5 with reactor coolant loops not filled, a single shutdown cooling loop provides sufficient heat removal capability for removing decay heat; but single failure considerations and the unavailability of the steam generators as a heat removing component, require that at least two shutdown cooling loops be OPERABLE-The operation of one Reactor Coolant Pump or one shutdown cooling pump provides adequate flow .to ensure mixing, prevent stratification and produce gradual reactivity changes during boron concentration reductions in the Reactor Coolant System. The reactivity change rate associated with boron reduc.ions will, therefore, be within the capability of operator 'recognition and control.

The restricttons on starting a Reactor Coolant Pump are provided to prevent RCS pressure transients, caused by energy additions from the secondary system, which could exceed the limits of Appendix 6 to 10 CFR 50.

The RCS will be protected against overpressure transients and will not exceed the limits of Appendix G by restricting starting of the Reactor Coolant Pumps to when the secondary water temperature of each steam generator is less than 30'F above each of the Reactor Coolant System cold leg temperatures.

I ~ A EI ALEE The pressurizer code safety valves operate to prevent the RCS from being pressurized above its Safety Limit of 2750 psia. Each safety valve is designed to relieve 2 x 10s lbs per hour of saturated steam at the valve setpoint. The relief capacity of a single safety valve is adequate to relieve any over-pressure condition which could occur during shutdown. In the event that no safety valves are OPERABLE, an operating shutdown cooling loop, connected to the RCS, provides overpressure relief capability and will prevent RCS overpressuriza-tion.

'EACTOR COOLANT S =M Attachment 3 Page 6 of 10 3/4 4.2 and 3/4.4.3 SAFETY VALVES Continued During operation, all pressurizer code safety valves must be OPERABLE to prevent the RCS from being pressurized above its safety limit of 2750 psia. Tne combined relief capacity of these valves is sufficient to limit the Reactor Coolant System pressure to within its Safety Limit of 2750 psia following a complete loss of turbine generator load while operating at RATED THERMAL POWER and assuming no reactor trip until the first Reactor Protective System trip setpoint (Pressurizer pressure-High) is reached (i.eno credit is taken for a direct reactor trip on the loss of turbine} and also assuming no operation of the pressurizer power operated relief valve or steam dump valves.

3/4.4.4 PRESSURlZER A steam bubble in the pressurizer ensures that the RCS is not a hydraulically solid system and is capable of accommodating pressure surges during operation. Tne steam bubble also protects the pressurizer code safety valves and power operated relief valve against water relief. The power operated relief valve and steam bubble function to relieve RCS pressure during all design transients. Operation of the power operated relief valve in conjunction with a reactor trip on a Pressurizer-Pressure-High signal minimizes the undesirable opening of the spring-loaded pressurizer code safety valves. The required pressuzier heater capacity is capable of maintaining natural circulation sub-cooling. Operability of the heaters, which are powered by a diesel generator bus, ensures ability to maintain pressure control even with loss of offsite power.

3/4.4.5 STEAM GENERATORS One OPERABLE steam generator provides sufficient heat removal capability to remove decay heat after a reactor shutdown. The requirement for two steam generators capable of removing decay heat, combined with the requirements of Specifications 3.7.1.1, 3.7.1.2 and 3.7.1.3 ensures adequate decay heat removal capabilities for RCS temperatures greater than 325'F if one steam generator becomes inoperable due to single failure considerations. Below 325'F, decay heat is removed by the shutdown cooling system.

The Surveillance Requiremer'" for inspection of the steam generator tubes ensure that the structural integrity of this portion of the RCS will be maintained. The program for inservice inspection of steam generator tubes is based on a modmcation of Regulatory Guide $ .83, Revision 1. Inservice inspection of steam generator tubing is essential in order to maintain surveillance of the conditions of the tubes in the event that there is evidence of mechanical damage or progressive degradation due to design, manufacturing errors, or in-service conditions that lead to corrosion. Insetvice inspection of Steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures can be taken.

'REACTOR COOLANT SY Attachment 4 Page 5 of 9 SAFETY VALVES Continued During operation, all pressurizer code safety valv s must be OPERABLE to prevent the RCS from being pressurized above its safety ltmit of 2750 psia. The combined relief capacity of these valves is sufficient to limit the system pressure to within its Safety Limit of 2750 psia following a complete loss of turbine generator load while operating at RATED THERMAL POWER and assuming no reactor trip until the first Reactor Protective System trip setpoint (Pressurizer Pressure-High) is reached (i.e., no credit is taken for a direct reactor trip on the loss of turbine) and also assuming no operation of the pressurizer power-operated relief valve or steam dump valves.

3/4.4.3 PRESSURIZER An OPERABLE pressurizer provides pressure control for the Reactor Coolant System during operations with both forced reactor coolant flow and with natural circulation flow.

The minimum water level in the pressurizer assures the pressurizer heaters, which are required to achieve and maintain pressure control, remain covered with water to prevent failure, which could occur if the heaters were energized uncovered. The maximum water level in the pressurizer ensures that this parameter is maintained within the envelope of operation assumed in the safety analysis. The maximum water level also ensures that the RCS is not a hydraulically solid system and that a steam bubble will be provided to accommodate pressure surges during operation. The steam bubble also protects the pressurizer code safety valves against water relief. The requirement to verify that on an Engineered Safety Features Actuation test signal concurrent with a loss of offsite power the pressurizer heaters are automatically shed from the emergency power sources is to ensure that the non-Class 1E heaters do not reduce the reliability of or overload the emergency power source; The requirement that a minimum number of pressurizer heaters be OPERABLE enhances the capability to control Reactor Coolant System pressure and establish and maintain natural circulation.

(1100 psia) of its design pressure of 1000 psia during the most severe anticipated system opera-tional transient. The maximum relieving capacity is associated with a turbine trip from 100~ RATED THERMAL POWER coincident with an assumed loss of condenser heat sink (i.e., no steam bypass to the condenser).

The specified valve lift settings and relieving capacities are in accordance with the requirements of Section III of the ASHE Boiler and Pressure Vessel Code, 1971 Edition, and ASME Code for Pumps and Valves, Class II. The to]al relieving capacity for all valves on all of the steam lines is 12.49 x 10 lbs/hr which is 103.8i. of the total secondary steam flow of 12.03 x 10 lbs/hr at lOOX RATED THERMAL POWER. A minimum of two OPERABLE safety valves per steam generator ensures that sufficient, relieving capacity is available for removing decay heat.

STARTUP and/or POMER OPERATION is allowable with safety valves inoperable within the limitations of the ACTION requirements on the basis of the reduction in secondary system steam flow and THERMAL POMER required by the reduced reactor trip settings of the Power Level-High channels. The reactor trip set-point reductions are derived on the following bases.:

For two loop operation:

SP = x (107.0) '- 0.9 where:

SP reduced reactor trip setpoint in percent of RATED THEE@L P.OMER maximum number of inoperable safety valves per steam line 107.0 Power Level-High Trip Setpoint for two loop operation 0.9 Equipment processing uncertai nty Total relieving capacity of'all safety valves per steam line in lbs/hour (6.247 x 106 lbs/hr) lose(+ S Maximum relieving capacity of any one safety vaIve in lbs/hour (7.74 x 105 lbs/hr)

Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 1 Page 2 EVALUATIONOF PROPOSED TS CHANGES 1.0 Introduction The proposed amendments to Facility Operating Licenses DPR-67 for St. Lucie Unit 1 (PSL1) and NPF-16 for St. Lucie Unit 2 (PSL2) will revise the Unit 1 and 2 license requirements for laboratory testing the ability of activated charcoal samples to remove radioactive methyl iodide (organic iodine form) when the sample is tested in accordance with ASTM D3803-1989 requirements for the following ventilation systems:

Table 1 Ventilation Systems with TS Requirements for Activated Charcoal Adsorber Testin Unit 1 Unit 2 Shield Building Ventilation System (SBVS), Shield Building Ventilation System(SBVS),

TS 4.6.6.1 TS 4.6.6.1 Control Room Emergency Ventilation System Control Room Emergency Air Cleanup CREVS TS 4.7.7.1 S stem CREACS TS 4.7.7 ECCS Area Ventilation System, TS 4.7.8.1 N/A For Unit 2, no credit for the ECCS Area filtration and cleanup systems in the accident anal sis.

Fuel Handling Building Ventilation System N/A For Unit 2, the SBVS performs the VS TS 4.9.12 filtration function On June 3, 1999, the NRC issued Generic Letter (GL) 99-02, Laboratory Testing of Nuclear-Grade Activated Charcoal. This GL was issued to alert licensees of the NRC determination that testing nuclear-grade activated charcoal to standards other than American Society of Testing and Materials (ASTM) D3803-1989, Standard Test Method for Nuclear-Grade Acrivared Carbon, does not provide assurance for complying with the current licensing basis as it relates to the dose limits of GDC 19 of 10 CFR 50, Appendix A, or 10 CFR 100 Subpart A.

The GL also requested that all licensees determine whether their Technical Specifications (TS) reference ASTM D3803-1989 for charcoal laboratory testing. Licensees, whose TS do not reference this standard, should either amend the TS to reference the standard or propose an alternative test protocol. The St. Lucie Unit 1 and Unit 2 TS do not currently reference this standard for the test protocol.

The St. Lucie units have been testing charcoal samples in accordance with the TS referencing the following standards: ANSI N510-1975 for Unit 1, and ANSI N510-1980 for Unit 2. The St. Lucie Unit 1 and Unit 2 TS do not reference R.G. 1.52 for testing. GL 99-02 action 2 requested Licensees to submit TS amendment requests within 180 days of June 3, 1999. The amendment request should adopt the ASTM D3803-1989 test protocol and should contain the test temperature, relative humidity (RH), and penetration at which the proposed TS will

't. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 1 Page 3 require the test to be performed and the basis for these values.

2.0 Back round Safety related air-cleaning units used in plant ventilation systems reduce the potential onsite and offsite consequences of radiological accidents by adsorbing radioiodine. Analyses of design bases accidents assume particular safety related charcoal adsorption efficiencies when calculating offsite and control room operator doses. Licensees then test the charcoal to determine whether the adsorber efficiency is greater than that assumed in the design basis accident analysis. To ensure that the charcoal adsorbers will perform in a manner that is consistent with the licensing basis, most licensees have requirements in their TS to periodically test samples of activated charcoal used in these ventilation systems.

The industry and NRC position on the appropriate laboratory tests for nuclear-grade charcoal has evolved over the years since the issuance of Regulatory Guide (RG) 1.52, Design, Testing, and Maintenance Criteria for Post-Accident Engineered Safety Feature Atmosphere Cleanup System Air Filtration and Adsorption Units of light-Water-Cooled Nuclear Power Plants, which is referenced in many plant TS. It was initially assumed that high-temperature/high-relative-humidity conditions were the most severe. Later, it became clear that the most conservative test is at low temperature and high humidity, The use of outdated test protocols or inappropriate test conditions can lead to an overestimate of the charcoal ability to adsorb radioiodine following an accident.

GL 99-02 classified the nuclear plants in four categories based on NRC sponsored surveys:

1. Plants in compliance with their TS that test in accordance with ASTM D3803-1989,
2. Plants in compliance with their TS that test in accordance with test protocols other than ASTM D3803-1989,
3. Plants not in compliance with their TS that test in accordance with ASTM D3803-1989, and
4. Plants not in compliance with their TS that test in accordance with test protocols other than ASTM D3803-1989.

The St. Lucie units have been testing charcoal samples in accordance with the TS referencing the following standards: ANSI N510-1975 for Unit 1, and ANSI N510-1980 for Unit 2.

Therefore, St. Lucie fits the GL 99-02 Category 2 designation. The St. Lucie Unit 1 and Unit 2 TS do not reference Regulatory Guide (RG) 1.52 for testing. However, both units were designed to RG 1.52 requirements as stated in the Updated Final Safety Analysis Report (UFSAR).

The shield building ventilation systems for both units have been designed to provide fission product removal capacity during design basis accident conditions. The SBVS consists of two full capacity redundant fan and filter subsystems, which share a common shield building duct intake and a common plant vent. Each filter subsystem consists of demisters, electric-heating coils, HEPA filters, and charcoal adsorbers enclosed in a common casing.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 1 Page 4 The control room emergency ventilation systems for both units have been designed to limit airborne radioactivity in the control room following a LOCA by recirculating control room air through charcoal adsorbers. This is required so that airborne radiological doses experienced by control room personnel following a design basis accident (DBA) do not exceed limits imposed by General Design Criterion 19. The control room ventilation system in both units are similar and they consist of split system air conditioners (i.e., indoor and outdoor section),

a ducted air intake and air distribution system, and a filter train with HEPA filters and charcoal adsorbers with two redundant booster centrifugal fans.

The Unit 1 emergency core cooling system (ECCS) area ventilation system is designed to provide post-LOCA filtration and adsorption of fission products in the exhaust air. Also, it limits the post accident radiological doses below the guidelines of 10 CFR 100 from areas of the reactor auxiliary building which contain the following equipment:

a) Containment isolation valves, b) Low pressure safety injection pumps, c) High-pressure safety injection pumps, d) Containment spray pumps, e) Shutdown heat exchangers, and f) Piping which contains recirculating containment sump water following a LOCA.

This ventilation system consists of two redundant centrifugal exhaust fans, HEPA and charcoal adsorbers, and associated ductwork, dampers and controls. The exhausted air is vented to the outside atmosphere.

The Fuel handling building (FHB) ventilation systems for both units serve the spent fuel pool areas. The Unit 1 FHB ventilation system is designed to reduce plant personnel doses by preventing the accumulation of airborne radioactivity in the fuel handling building due to diffusion of fission products from the spent fuel pool. This system is also designed to ventilate the spent fuel cooling equipment contained within the fuel handling building. This ventilation system consists of two separate supply systems and two separate exhaust systems. Each supply system consists of a hooded wall intake, an air handling unit with filters, a fan section, and a duct distribution system. One system supplies air to the fuel pool area and the other system supplies air to the lower areas, The fuel pool area air is exhausted through air inlets around the periphery of the fuel pool. Air is discharged by two 100 percent capacity centrifugal fans to the atmosphere through a prefilter, HEPA filter bank, charcoal absorbers and out the FHB vent stack. Air exhaust from the lower areas is passed through a prefilter and HEPA filter bank before being discharged by a centrifugal fan to the atmosphere through the FHB vent stack.

The portion of Unit 2 FHB ventilation system for the spent fuel pool ventilation is interconnected with the SBVS. In the event of a high radiation signal, the fuel pool area is exhausted to the plant vent via the SBVS filters.

The current charcoal adsorber testing protocol used for Unit 1 per ANSI N510-1975 is performed in accordance with Table 4 of RTD M 16-1'. According to this table, charcoal testing for radioactive methyl iodide at 130 C and 95% relative humidity is performed as follows:

The test sample is pre-equilibrated with air at the above conditions until the temperature differential across the test bed is less than 1'C. With continuing air flow, steam is injected. adjusting it to maintain partial pressure of air at 20 +I-2 psia and steam at 95 +/- 1% of the saturated water pressure at the measured test temperature. The challenge gas (methyl iodide) is injected for 1.5 hrs.

After iodine injection is stopped, steam-air injection is continued for another 1.5 hrs. Then, the test bed is allowed to cool, removed, and count tested to calculate ejji ciency.

The current charcoal adsorber testing protocol used for Unit 2 per ANSI N510-1980 is performed in accordance with ASTM D3803 (1979). According to this standard, charcoal testing for radioactive methyl iodide at 130 C and 95% relative humidity is performed as follows:

The conditions are maintained for an equilibriuIn period of at least two hours, or until the temperature differential across the bed is less than 2'C. These conditions are continued during the challenging period when a spectflc amount of methyl iodide is added to the test gas flowfor one hour. Afier this period, the flow conditions are maintained for a 240-minute elution period without the addition of the methyl iodide. A substantial amount of condensed water is collected during the test, and any radioactivity contained in it is assumed to have penetrated the carbon bed. For tests of used charcoal, the carbon sample U.S. AEC, Division of Reactor Research and Development, RDT Standard M16-1T, "Gas-Phase Adsorbents for Trapping Radioactive Iodine and iodine Compounds", Oct. 1973.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 1 Page 7 is not exposed to humid airflowfor a pre-equilibration period. Instead, the bed is brought to the test temperature without airflow, followed by the challenging period.

According to GL 99-02, studies by EG&G reported that this standard (ASTM D3803-1979) had unacceptable test parameter tolerances and instrument calibration requirements, and that the standard was non-conservative in not requiring humidity pre-equilibration of used charcoals.

The proposed charcoal adsorber-testing protocol (ASTM D3803-1989), which will be incorporated for both units per the proposed amendments, will be performed as follows:

The test sample is exposed to air at 30'C and 95% RH (1 atmosphere) for a pre-equilibrium period of 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />, followed by airflow at equilibrium for 2-hours.

During the challenge period, methyl iodide is injected at a fixed mass concentration for 1-hour. This is followed by injection of humid air only for another hour (elution period). Throughout the entire test the effluent Pom the sample bed passes through two backup beds containing carbon having a known high ej1iciency for methyl iodide. The beds trap all methyl iodide that passes the test bed and provide a differential indication of their eJJtciency. At the end of the elution period, the I-131 gamma activity is measured and the percent of adsorbate penetrating the test bed is determined.

The results of the ASTM D3803-1989 test protocol provide a conservative estimate of the performance of nuclear-grade activated charcoals used in all nuclear power plant ventilation systems for the removal of iodine. Also, according to this standard, the 30'C, 95% RH methyl iodide test is the most reliable test protocol to establish the methyl iodide removal efficiency of any adsorbent. The NRC has agreed with these conclusions as demonstrated by the fact that the ASTM D3803-1989 protocol is accepted and endorsed by the NRC in GL 99-

02. Additionally, the Committee on Nuclear Air and Gas Treatment (CONAGT) and NRC-INEL discussions have concluded that the humidity pre-equilibration at 30'C for used charcoals results in a more conservative test than the non pre-equilibration required by previous versions of ASTM D3803. It is then concluded that the new proposed testing protocol per ASTM D3803-1989 at 30'C, 95% RH with different pre-equilibration, testing, and elution techniques which is now endorsed by the NRC and results in more conservative results than other test methods, is an acceptable methodology for the St. Lucie safety related ESF ventilation system charcoal testing.

r, The UFSAR discusses the need for charcoal testing of the safety related ventilation systems as defined in Table 1 of this attachment, and with the conservative methyl iodide penetration requirements stated in the Technical Specifications. However, testing of the Unit 2 ECCS ventilation system charcoal beds is not required from a licensing point of view as concluded in the NRC Initial Operating License Safety Evaluation Report (NUREG-0843). Also, the Unit 2 fuel pool ventilation system is interconnected to the SBVS, and during accident conditions, airflow from the fuel handling building is routed through the SBVS. For these reasons, the

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 1 Page 8 Unit 2 ECCS and FHB ventilation systems are not required to be tested for methyl iodide penetration.

Based on the above information, the assumed accident analysis penetration values for each ESF ventilation system along with FPL proposed penetration values for methyl iodide testing, based on a minimum safety factor value of 2 is shown below:

Table 2 Allowable Values ESF Ventilation System Assumed GL 99-02 Proposed Proposed TS Accident Maximum Maximum Minimum Analysis Allowable Allowable Allowable Penetration Penetration with Penetration Efficiency SF=2 Unit 1 SBVS 30% 15% 10% 90%

Unit 1 ECCS Area Ventilation 30% 15% 10%

S stem Unit 1 CREVS 30% 15% 10% 90%

Unit 1 FHBVS 30% 15% 15% 85%

Unit 2 SBVS 50% 10% 90%

Unit 2 CREACS 1% 0.5% 0.175% 99.825%

From above, it is clear that the penetration values proposed by this proposed amendment are the same as or more conservative than the values correlated to a safety factor of 2 which is the minimum value allowed by GL 99-02. (Safety factor is defined as the ratio between the penetration value assumed in the accident analysis to the allowable testing value). The proposed penetration values are equivalent to charcoal adsorber efficiencies provided above and in the TS markups (Attachments 3 and 4). The maximum allowable penetration values in the proposed TS will be kept the same as the values currently provided in the TS for all the systems except the Unit 1 FHBVS. This will provide additional conservatism. For the Unit 1 FHBVS the proposed maximum allowable penetration value basis is discussed below. The decision to maintain the same penetration values was based on maintaining the same level of conservatism currently established while providing operating flexibility. According to the charcoal testing vendor, for the most limiting case shown above (Unit 2 CREACS) which has a higher safety factor than 2, this translates into a charcoal adsorber availability for several years without being changed out. This is based on testing of charcoal adsorbers from other facilities similar to St, Lucie.

Since a methyl iodide testing criteria is currently not provided for the fuel handling building ventilation for Unit 1 (existing TS only test for elemental iodine), a penetration value for methyl iodide testing is being proposed for this specification. The proposed penetration value is based on the 30% penetration assumed in the accident analysis and applying a safety factor of 2, the minimum value allowed by GL 99-02. Therefore, a penetration testing criteria of 15% will be incorporated into the Technical Specifications for this system, equivalent to charcoal adsorber efficiency of 85%.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 1 Page 9 With regards to the proposed testing relative humidity (95%), this value is also more conservative than the value assumed in the accident analysis. Normally, a relative humidity (RH) of 70% is maintained at all times (including post-accident) by the SBVS in both units.

This is achieved by redundant electrical heaters provided for each train of SBVS. For the other ESF ventilation systems located outside containment, the UFSARs assume that based on system configurations, it is not expected that the relative humidity for charcoal adsorbers will be higher than 70% even without the use of heaters. The proposed RH value (95%) is much larger than 70% and it is more conservative because increasing the RH of the test generally decreases the efficiency of methyl iodide removal by activated carbon.

The testing temperature for the proposed TS wiH be 30'C instead of the current value of 130'C, to be consistent with the recommendations provided in GL 99-02.

In addition to the proposed Technical Specification changes from above, the requirement to perform elemental iodine testing will be removed from applicable TS to be consistent with GL 99-02 guidance that requires only methyl iodide testing for charcoal adsorber efficiency.

There is no safety significance associated with implementing a more conservative charcoal testing protocol than previous tests. The new testing methodology will eliminate the potential for having overestimation of the charcoal bed efficiency. Therefore, testing at lower temperatures provides for a more conservative approach for the charcoal to react to the plant conditions existing during design basis accidents. There are no modifications to safety-related equipment or adverse effects imposed by the new testing methodology. Therefore, all safety related structures, systems, and components remain unaffected and still capable of performing their design basis functions. The St. Lucie plant complies with 10 CFR 50 Appendix A, General Design Criterion 19 and 10 CFR 100, Subpart A.

4.0 Environmental Consideration The proposed license amendments change requirements with respect to surveillance requirements. The amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite, and no significant increase in individual or cumulative occupational radiation exposure. FPL has concluded that the proposed amendments involve no significant hazards consideration and meet the criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). FPL has determined pursuant to 10 CFR 51.22(b), that an environmental impact statement or environmental assessment need not be prepared in connection with issuance of the amendments 5.0 Conclusion Based on review of the licensing bases documentation and evaluation presented above, the new testing protocol and testing conditions proposed by this evaluation provide a more conservative approach to laboratory testing of charcoal adsorbers for safety related ventilation systems. The requirements of General Design Criterion 19 and 10 CFR 100 Subpart A are maintained. The proposed new testing methodology will ensure the design basis of each plant (relative to

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 1 Page 10 methyl iodide removal) is maintained and that safety analysis assumptions remain valid.

Lucie Unit 1 and 2 Docket Nos. 50-335 and 50-389 L-99-241 Attachment 2 Page 2 DETEZG'GNATION OF NO SIGNIFICANT HAZARDS CONSIDERATION Description ofamendment request:

The amendments will revise the St. Lucie Unit 1 and 2 TS to require laboratory testing of activated charcoal samples for applicable engineered safety feature (ESF) ventilation systems using the ASTM D3803-1989 protocol. The affected TS are Units 1 and 2 shield building ventilation system, TS 4.6.6.1; Unit 1 ECCS area ventilation system, TS 4.7.8.1; Unit 1 control room emergency ventilation system, TS 4.7.7.1; Unit 2 control room emergency air cleanup system, TS 4.7.7; and Unit 1 fuel pool ventilation system fuel storage, TS 4.9.12.

Pursuant to 10 CFR 50.92, a determination may be made that a proposed license amendment involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not: (1) involve a signiTicant increase in the probability or consequences of an accident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety. Each standard is discussed as foHows:

(1) Operation of the facility in accordance with the proposed amendment would not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed amendment does not involve a signiTicant increase in the probability or consequences of any accident previously evaluated. The new charcoal testing protocol is performed offsite on samples extracted from the safety-related ventilation systems. Therefore, there is no impact on any accident initiator and therefore, no changes on the probability. The proposed testing protocol is more conservative than previous tests; therefore, the efficiency of charcoal for the affected safety-related systems would not be overestimated. With the new testing protocol, more conservative testing results are expected since the temperature at which testing is performed is lower and the charcoal retention capability is more consistent with actual accident conditions. The proposed change thus ensures that the charcoal in service will comply with the penetration requirements to meet the design basis accident conditions.

Therefore, operation of the facility in accordance with the proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

(2) Operation of the facility in accordance with the proposed amendment would not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed amendment will not create the possibility of a new or different kind of accident from any accident previously evaluated. The proposed new charcoal testing protocol only affects surveillance testing requirements for ventilation systems. The functions of these

g E J

sy'stems remain unchanged and unaffected. No new system interactions have been introduced by the proposed amendment, which would create a new or different type of accident than previously analyzed. No physical changes are being made to any structure, system or component. The operation of the facility has not been altered by the proposed amendment.

The systems involved are not considered to initiate any accidents as previously evaluated.

The proposed amendment will not change the physical plant or the modes of operation defined in the facility license. The changes do not involve the addition of new equipment or the modification of existing equipment, nor do they alter the design of St. Lucie plant systems. Therefore, operation of the facility in accordance with the proposed amendment would not create the possibility of a new or different kind of accident from any accident previously evaluated.

(3) Operation of the facility in accordance with the proposed amendment would not involve a significant reduction in a margin of safety.

The proposed amendment does not involve a reduction in the margin of safety. The margin of safety of the Technical Specifications, its bases, the Final Safety Analysis Report, the Safety Evaluation Report or in any other design document has not been affected by the proposed amendment. The change provided in this proposed amendment is related to introducing an improved testing protocol for the activated charcoal in safety related ventilation systems. The change consists of testing the charcoal with a new testing protocol and with lower test temperatures to resemble more closely accident conditions and to eliminate potential overestimation of charcoal efficiency.

Therefor, operation of the facility in accordance with the proposed amendment would not involve a significant reduction in a margin of safety.

Based on the discussion presented above and on the supporting evaluation of proposed TS changes, FPL has concluded that these proposed license amendments involve no significant hazards consideration.

NOV,O 8 1999 L-99-234 10 CFR Part 54 U. S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555 Re: St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 Submittal Plan for License Renewal A lication The purpose of this letter is to inform the Nuclear Regulatory Commission and its staff of Florida Power and Light Company's (FPL) plans to submit a license renewal application for St. Lucie Units 1 and 2 by the end of June 2002. FPL is encouraged by the progress in the NRC's review of the Calvert Cliffs and Oconee license renewal applications and believes that license renewal can be accomplished for St. Lucie in an economical and timely manner.

FPL recognizes that the application for a renewed license for St. Lucie Unit 2 would be submitted more than 20 years prior to expiration of the existing license (2023). Accordingly, FPL will submit a request for exemption per 10 CFR Part 50.12 from the requirements of 10 CFR Part 54.17(c) by the end of 2000.
