SAFETY EVALUATION REPORT

_ TECHNICAL SPECIFICATION CHANGES (MPA B-90)

SEQUOYAH NUCLEAR STATION, UNITS I AND 2 INTRODUCTION By letter dated May 23, 1986, TVA proposed changer to the Sequoyah Technical SpecificationspertainingtoReactorTripSystemInhtrumentationandSurveillance in response to Generic Letter 85-09 (MPA B-90). Generic Letter 85-09 concluded that Technical Specification changes should be proposed by licensees to explicitly require independent testing of the undervoltage and shunt trip attachments of the reactor trip breakers during power operation, testing of bypass breakers prior to use, and independent testing of the control room manual switch contacts and wiring during each refueling outage.

EVALUATION TVA's proposed Technical Specification changes are consistent with those specified in Generic Letter 85-09, except as indicated below by items 1,2 and 3.

1.

A different Action than that indicated is needed for Modes 3*,4* and 5*

(asterisk means with the reactor trip system breakers in the closed posi-tion, the controi rod drive system capable of rod withdrawal, and fuel in the reactor vessel) for Functional Units 20 and 21 of Table 3.3-1.

2.

No provision is included for testing of the Reactor Trip Bypass Breaker prior to each time it is put into service.

3.

No provision is included for verifying the operability of the Bypass Breaker trip circuits each refueling outage.

8612110386 861205 PDR ADOCK 05000424 A PDR

The proposed Technical Specification changes for Functional Units 20 (Reactor Trip Breakers) and 21 (Automatic Trip Logic) apply the same Action 12 to all Applicable Modes. Action 12, which requires going to Hot Standby under certain conditions, is not appropriate for Modes 3*,4* and 5*.

For Modes 3*,4* and 5*,

tha-reactor trip breakers should be opened if the condition is not remedied within a given time period as specified in Action 13 of Generic Letter 85-09.

TVA has declined to provide Technical Specification changes for surveillance testing of the reactor trip bypass breakers on the basis that Westinghouse Owners Group (WOG) calculations have shown no significant reliability improvement from including periodic surveillance tests of the bypass breakers in the technical specifications. This is not acceptable to the NRC staff. When a reactor trip breaker is tested, the reactor trip bypass breaker is put into service in its place. The Generic Letter 85-09 Technical Specifications specify (Table Notation 13) a manual test of the bypass breaker (either a local shunt trip or remote undervoltage trip) prict to putting it into service. This testing is a simple procedure and it is prudent to do this test before relying on the breaker.

The Generic Letter 85-09 Technical Specifications (Table Notation 11) also re-quires a manual trip function test to independently verify the Operability of the undervoltage and shunt trip circuits of the Bypass Breakers each refueling outage. This test is important to assure that the bypass breaker' can be manu-ally tripped from the control panel.

I

t CONCLUSION '

The licensee should amend its proposed Technical Specification changes by

1. proposing a different Action than that indicated for Modes 3*,4* and 5* for Functional Units 20 and 21 of Table 3.3-1,
2. including provisions for testing the Reactor Trip Bypass Breaker prior to each time it is put into service, and
3. including a provision for verifying the operability of the Bypass Breaker trip circuits each refueling outage.

Each of the above changes should be in accordance with Generic Letter 85-09.

Leak Testing of Pressure Isolation Valves Request for Additional Information 210. Mechanical Engineering Branch f.

The Surveillance Requirement pertaining to leak testing of pressure isolation valves (PIVs) presented in Section 4.4.3.2.2 of Perry Draft Technical Specification is not complete. In addition to the two requirements currently identified in Perry draft Technical Specification, Section 4.4.3.2.2, the staff requires the PIVS to be leak tested (a) prior to entering the Hot Shutdown whenever the plant has been in Cold Shutdown for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or more and if leakage testing has not been performed in the previous 9 months and (b) within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following valve actuation due to automatic or manual action or flow through the valve. Provide additional information to assure that the Perry plant has the following plant features: (1) full closure of PIV's is verified in the control room by direct monitoring position indicators, (2) inadvertent opening of PIV's is prevented by interlocks which require the primary system pressure to be below subsystem design pressure prior to openings, and (3) gross intersystem leakages into the low-pressure core spray, residual heat removal / low-pressure coolant injection, and residual heat removal / shutdown cooling return and suction lines would be detected by high-pressure alarms and increases in the suppression pool level.

With these plant features in place, the PIV's are controlled and verified continuot. sly rather than at the intervals specified in (a) and (b) above and then, the exception for relief from the surveillance requirements (a) and (b) could be accepted. "

Index Page XIX: Section 3/4.9.6 title does not agree with title on page B 3/4 9-2.

Index Page XIX: Section 3/4.9.12 listed does not have a basis in TS.

3.1.3.2 This TS as written only applies to the control rod positions. This should be shutdown and control rod positions for clarification as done in TS 3.1.3.3.

3.1.3.3 The

, System breakers in the closed position" appears unnecessary in that the action statement would control with the standard phrase The provisions of 3.0.4 and 4.0.4 would apply.

Table 2.2-1 A number of the values given here are discrepant with a letter dated September 29, 1986, f' rom the Vogtle Project to Mr.

Denton entitled WCAP 11269 (proprietary) and 11270 (non proprietary),

" Westinghouse Setpoint Methodology for

- Protection Systems - Vogtle Station" Since this letter is addressed to NRR, we will not compare them directly except in areas that we feel may still be unclear. One such example concerns Functional Unit 16, Turbine Trip. The WCAP report leaves theso values blank while the proposed TS value for Turbine Stop Valve Closure is extremely non-conservative with respect to STS (DRAFT) Rev. 5 which lists >1% open for both the Trip Setpoint and Allowable Value while the proposed Vogtle TS lists

>97.6%. Additionally, Notes 1 & 3 of the

, proposed Vogtle TS and the WCAP values denote variable time constants while the STS uses equal signs. Also, the

  • symbol means two different items.

3.2.2 Remove brackets around constants in i equation as these are site specific l numbers.

l 3.3.1 & 4.3.1.2 The surveillance calls for checking the response times within the limits while the limits are no longer a part of TS 3.3.1. If these limits are to be in the FSAR, then the proper references should be made.

3.3.2 & 4.3.2.2 Same comments as above regarding l response times.

Pressurizer pressure-low, reactor

! coolant pump-under voltage, and reactor l coolant pump underfrequency are only applicable above the P-7 interlock. This I is not as conservative as the guidance l

The same applies to 6a. and 6b. Action statement 12 also states 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> instead of the 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> used in the STS. Action statement 13 is non-conservative and has ATWS implications.

Table 4.3-1 It should be noted that there is no table given for Reactor Trip System response times. Nearly all of the functional units in the Reactor Trip

- System Instrumentation Surveillance Requirements replaced the monthly surveillances for the analog channel operational test given in the STS with quarterly or refueling or startup surveillances. This is a matter that should require some sort of justification for making such a sweeping non-conservative alteration from STS.

Table 3.3-2 The ESFAS instrumentation table has no functional unit heading or channel trip criteria for Steam Line Flow High with or without Lo-Lo T-ave. Neither is there a functional unit for Under Voltage to the RCP's starting the Turbine Driven AFW pumps. This whole table is weak with respect to the AFW system. Additionally, there is no functional unit dealing with an ESF start due to steam generator water level or Lo-Lo T-ave.

Table 3.3-3 The values in this table were also addressed in the WCAP 11269 report transmitted September 29,1986 to B.J.

Youngblood from the Vogtle Project.

There were no problems encountered with this WCAP data.

Table 4.3-2 It should be noted that there is no table given for the ESF system response time. There are similar discrepancies in i this table as there were in Table 3.3-2.  :

There are no funtional units covering the surveillance of differential pressure between two steam lines, high steam flow in two lines coincident with Lo-Lo T-ave, no undervoltage to the RCP's, nor any ESFAS interlocks at P-12 i or P-14.

3.3.3.8 The loose part detection TS is missing.

4.4.1.2.2 , These TS all reference secondary side-4.4.1.3.2, & water level values at 17% which is 3.4.1.4.1b non-conservative per WCAP 11269. See general comments.

3.4.1.4.2 Typo "RHR" has been deleted before the word " trains" in action statement a.

3.4.2.1 Clarification- TS 3.4.1.4.2 changed the terminology from "RHR Loop" to "RHR Train". This TS needs the action statement changed to reflect consistent terminology.

4.4.3 The surveillance should add the following step: The emergency power supply for the pressurizer heaters should be demonstrated operable at least once per 18 months by manually transferring power from the normal to the emergency power supply and energizing the heaters.

3.4.9.3 SAFETY CONCERN- Typically, reliance on the RHR relief valves is not appropriate since the suction valves will isolate to protect RHR at the sacrifice of the RCS.

The vent path option capable of relieving 670 GPM appears inadequate in that these TS no longer will require one of two charging pumps inoperable thus allowing for a potential of 1,000 GPM. '

It should also be noted that the vent path only has to be " capable of relieving" where the STS would require the path to be open and thus not require human intervention.

3.6.2.1 & 3.6.2.3 SAFETY CONCERN- The STS was written for a plant where the Containment Spray Systems and Containment Cooling Systems are redundant to each other. At Vogtle this is not the case. With one spray system out, you must have both cooling trains and vice versa. With this in mind, TS 3.6.2.3 Actions a,b.and c rely on the other system to provide the necessary cooling capability. It is suggested that a format such as TS 3.5.2 be utilized to combine TS's 3.6.2.1 & 3.6.2.3 and possibly 3.6.2.2 to reflect a cooling train concept and eliminate the excessive outage times.

I 3.6.2.3 1) See above. .

2) The applicant has only provided for 100% cooling capacity as designed, not as would be required to cool containment; the spray system is necessary to reach a 100% cooling capacity.

3.7.1.3 Action a. should read," Demonstrate the operability of CST V4002 as a backup supply to the auxiliary feedwater pumps and restore CST V4001 to.....Also, delete the word vessel from the LCO.

3.7.1.5 & 4.7.1.5 A normal Westinghouse PWR has a check valve and one MSIV per steam line. The STS allows inoperability of the MSIV for four hours and relies on the check valve. This TS's action a allows both MSIV's (no check valve exists) to be inoperable for four hours and then only requires one to be restored. Both actions a and b appear innappropriate in a that they take credit for the added MSIV but do not reflect the deletion of the check valve.

This specification and its associated surveillance do not resemble STS at all and appear to be less conservative.

This whole Specification should be examined.

4.7.3 There is no surveillance requirement to verify every 18 months during shutdown, that each automatic valve servicing safety-related equipment actuates to its correct position on a Safety Injection test signal.

4.7.6.c.1 99.95% filter efficiency should most likely be,"in place penetration and bypass leakage type test."

4.8.1.1.1b SAFETY CONCERN-Reinstate this surveillance. The applicant has proposed deletion on the basis that this does not apply because the plant does not have a transfer feature for the 1E bus. This specification was written to test all of the bus transfers that interface between the offsite transmission circuit and the onsite 1E distribution system. This will i still leave seven bus transfers that '

i must be demonstrated as operable independent circuits.

4.8.1.1.2c & d SAFETY CONCERN- The applicant should add to the surveillance the requirement to I compensate for the fact that fuel oil will be stored in contact with inorganic zinc coating. See GPC letter dated June 4, 1986 in response to module 13B coatings regarding NRC IEC No. 77-15.

This is a site specific item.

4.8.1.1.2.5 Clarification needed- Is the loading of the D/G supposed to be from the time they start to load or from the time a start signal is received. It appears that this test should be integrated into TS 4.8.1.2.4.

'. slow when compared to 4.8.1.1.3g.4b page 3/4 8-6 which requires energization of the 1E bus within 10 seconds. Normal RPM i is 450.

3.8.2.1 This action statement sets no time frame for complete restoration.(i.e. If a battery bank is inoperable, then all I need is a charger to remain at power forever.) Suggest that the wording be:

a) With one of the hbove D.C. electrical sources inoperable, restore the inoperable D.C. electrical source to operable status within two hours or be in at least...

b) Immediately verify both chargers are operable and inservice within two hours and restore the battery bank to operable status within four hours, or be in at least.... This will allow time to restore the battery by taking advantage of the second charger availability.

4.8.2.1.e.4 Change "The battery charger" to "Each battery charger" since there is more than one per battery bank.

Table 4.8-2 The float voltages and specific gravities are not appropriate. The float

. voltages should be:

Cat. A Cat. B Allowable 12.20 12.20 12.17 specific gravity.

The nominal specific gravity of these batteries is 1.210, therefore these values appear to be too low (i.e. Cat B allowable being 11.190 is 20 points below nominal which indicates a discharged condition, not an operable condition.

3.11.1.1 & 3.11.2.1 SAFETY CONCERN- Since the TS has been modified to no longer require a plant shutdown if action a cannot be satisfied (i.e. immediately), then additional actions should be specified. This specification had self-regulation when tied to the reactor as the ultimate source of all radioactive material. It is recommended that action b be deleted unless other appropriate actions are j specified.

Table 3.12-2 The reporting level for activities are discrepant with the STS for a number of samples, all non-conservative. THese are: Zr-95 in water should be 300 instead of 400; Nb-95 in water should be 400 instead of 600; and La-140 in milk should be 300 instead of 400. Similarly, the lower limits of detection given are also non-conservative. These are: Zr-95 in water should be 15 instead of 30; Ba-140 in water should be 15 instead of 60; and Ba-140 in milk should be 15 instead of 60.

Administrative Controls .

6.1.2 This item deviates from the requirement to have a corporate officer, not the GMVNO perform this. See TMI item I.C.3 and I.A.l.2.

6.2.2e This specification has reduced GL 82-12 requirements in that:

1) Only overtime that exceeds the guidelines is reviewed. The STS has individual overtime reviewed monthly N which is the only means of monitoring 1

- gY the 40 hour4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> objective.

p 2) The level of authorization is too low for the approval of excess overtime, it resides at the same level that approves regular overtime.

6.7.2 First line- add reference as to who reviews the procedures. This specification as written only requires periodic review (see last line). See below Suggest that 6.7.2 read:

Each procedure of 6.7.1 above, and changes thereto, Shall be reviewed and approved by the GMVNO or the department head of the responsible department, and the PRB, as delineated in 6.4.1.6 and 6.4.1.7a, prior to implementation and reviewed periodically as set forth in administrative procedures. The GMVNO shall review and approve the following procedures:...

6.7.3c 1) The " Reviewed in accordance with Specification 6.7.2" will only require periodic review.

2) The GMVNO does not review all l

changes. Suggest that 6.7.3c be changed 15 I

reviewed, and approved in accordance with section 6.7.2 within 14 days of implementation.

6.12.2b Clarify who accepts- suggest:"b shall

- become effective upon review and acceptance by the PRB and approval per Specification 6.7.2 4

6.13.2b Same as for 6.12.2b above.

General Comments

1) The TABLES AND FIGURES listed in the index should be indexed if fifteen spaces. For ease of readability.

. 2) Will TS 3.3.3.8, " LOOSE PART DETECTION SYSTEM" be in the TS or not.

If it is to be deleted, then TS 3.3.3.9 and higher need to be renumbered.

3) TS on page 3/4 6-20 should be listed as 3/4.6.5 vice 3/4.6.6.
4) The WESTINGHOUSE SETPOINT METHODOLOGY FOR PROTECTION SYSTEMS-VOGTLE STATION (WCAP 11269) needs to be incorporated into the Technical Specification Tables 2.2-1 and 3.3-3 to eliminate non-conservative values. Submitted to the NRC September 29, 1986.

Also affects TS's 4.4.1.2.2, 4.4.1.3.2 & 3.4.1.4.1b

5) Several Tables have been removed from the TS which is probably part

~

of a TS upgrade program. Proper references to where the information now resides must be made. If not directly as part of the TS, then in the bases section. Currently the bases sections have not been revised and read as if the tablos still exist.

6) In several action statements the words, " pursuant to Specification 6.9.2" appear. All actions need to be section 6.8.2 since this is the special report section.

however, the Technical Specification Basis (Page B2-4) s'tates that no credit was taken for these trips. Technical Specification Table 3.3-2 states that delay' times for the source and intermediate trip functions are not applicable.

Correct this apparent inconsistency between the Technical Specifications and the safety analysis as required by 10 CFR 50.36.

Response

In response to this concern and to the concerns raised in Part c. below, we are

- . preposing changes to Taoles 3.3-1 and 3.3-2 of the Technical Specifications wh ch will a) require two source range channels to be operable in modes 3-5 whenever the rods are energized and capable of being withdrawn and b) require response time testing for the source range channels. Under the revised tables, the source range trip will not be blocked during a startup until the power range channels are available. As such, the intermediate range trips are redundant and no credit.is taken for them in the safety analyses.

Table 3.3-2 of the Specifications will be revised to specify acceptable reactor trip system instrumentation response times of < 0.5 seconds for the source range 28 m

when the sour _c_e range. trip s.igna.l is. y,enerated (when the core is ,%t or.just below critical) and the time when the protection is actually needed (significant power generation occurring)- see, for example Figures.15.2-1 to 15.2-3 in the 'JISAR.

The 0.5 second response time, which is used for consistency with with t'.se other channels, is therefore more than adequate to protect against rod withdrawal e/ents in modes 3-5. We have determined that response time testing of these channels can be implemented with minimal dif ficulty.
