SUMMARY

The proposed changes involve incorporating the results of work performed by the Boiling Vater Reactor Owners' Group (BVROG) concerning elimination of selected response time testing requirements, and incorporating the guidance given by Generic Letter 93-08 concerning relocation of Technical Specification Tables dealing with instrument response time limits.

The changes dealing with elimination of selected response time test requirements are supported by an analysis performed by the BVROG in NED0-32291, " System Analyses for the Elimination of Selected Rub anse Time Testing Requirements" dated January 1994, and the letter submittcd to the NRC staff from T. Green to P. Loeser dated April 15, 1994. The NRC documented completion of their review and approval of this analysis in a letter to R. A. Pinelli dated December 28, 1994. The analysis demonstrated that other periodic tests required by Technical Specifications, such as channel calibrations, channel checks, channel functional tests, and logic system functional tests ensure that instrument response times are within acceptable limits. In the interests of the Perry Nuclear Power Plant, the Cleveland Electric Illuminating Company was a participating utility in this effort, as noted in Appendix A to NED0-32291. Appendix 11 to NED0-32291 includes marked up pages of the Perry Nuclear Power Plant, Unit 1, Technical Specifications. It has been confirmed that NED0-32291 is applicable to the Perry Nuclear Power Plant.

This portion of the proposed changes eliminates selected response time testing requirements from Technical Specifications. Specifically, the response time testing requirements to be eliminated include sensors and specified loop instrumentation for the 1) Reactor Protection System (RPS), 2) Isolation System, and 3) Emergency Core Cooling System (ECCS). The BVROG evaluation confirms that response time tests are of no safety significance and cause unnecessary personnel exposure, reduce availability of safety systems during shutdown and are a significant burden to utility resources.

As part of the elimination of the selected components from response time testing, it is proposed that the ECCS RESPONSE TIME test requirement be moved from the ECCS actuation instrumentation Limiting Condition for Operation (LCO 3/4.3.3) to the ECCS LC0 (LCO 3.5.1). This change is appropriate since the.ECCS actuation instrumentation loops have been eliminated from the ECCS RESPONSE TIME testing requirements per NED0-32291. This proposal vill also change the Frequency for the Surveillance from 18 months on a STAGGERED TEST BASIS to 18 months in order to relate the appropriate frequency for testing the associated ECCS subsystem rather than the instrument channel. Moving the surveillance requirement from the instrumentation section to the systems section of the Technical Specifications also changes the Applicability for the surveillance requirement.

The proposed changes dealing with relocation of the instrument response time limit tables from the Technical Specifications are consistent with the guidance provided by Generic Letter 93-08 dated December 29, 1993. This Generic Letter does not result in any reduction of response time testing requirements. The Generic Letter provides guidance on relocating the response time test limits to the Updated Safety Analysis Report (USAR). In this manner, future changes to these time limits would be handled under the provisions of 10CFR50.59. The l

l

l PY-CEI/NRR-1932 L Attcchment 1 Page 2 of'10 tables being relocated include tables for instrumentation in the Reactor Protection System, Isolation System, Emergency Core Cooling System, and End of Cycle Recirculation pump trip system.

Due to requesting the relocation of the response time test-tables, many of the response time testing requirements that would have been proposed for elimination vill not be apparent in the proposed mark up of the Technical Specification pages. The intent is to utilize mil of the flexibility provided in NEDO-32291 for the Perry Nuclear Power Plant.

DESCRIPTION OF PROPOSED CRANGES .

The following is a description of the proposed changes: ,

1. Definition 1.13 (page 1-3) Add a sentence which states " Exceptions are [

stated in the individual surveillance requirements." This is to clarify the definition with the changes that are being  ;

made consistent with NED0-32291.  ;

2. Definition 1.21 (page 1-4) Add a sentence which states " Exceptions are i stated in the individual surveillance I requirements." This is to clarify the definition with the changes that are being  !

made consistent with NED0-32291. l

3. Definition 1.37 i (page 1-7) Add a sentence which states " Exceptions are  :

stated in the individual surveillance l requirements." This is t_ clarify the  !

definition with the changes that are being l made consistent with NED0-32291.  !

4. LCO 3.3.1 (page 3/4 3-1) End the LCO sentence after the word >

"0PERABLE", and delete the remainder of the  !

sentence. This is consistent with Generic  :

Letter 93-08. j

5. Surveillance Requirement j 4.3.1.3 (page 3/4 3-1) Delete the phrase "shown in Table 3.3.1.2".  !

This is consistent with Generic Letter 93-08.  ;

Add the following after the first sentence:

" Neutron detectors are exempt from response time testing." This is consistent with j Generic Letter 93-08.

PY-CEI/NRR-1932 L Attcchment 1 Page 3 of 10

5. (continued) Add a sentence following the sentence added above which states: "For Table 3.3.1-1 Functional Units 3, 4, and 5, the channel sensors are excluded from response time testing." This is consistent with NED0-32291 as approved by the NRC SER.

6. Table 3.3.1-2 (page 3/4 3-6) Delete this Table. This is consistent with Generic Letter 93-08

7. LCO 3.3.2 (page 3/4 3-9) End LCO sentence after the words " Table 3.3.2-2", and delete remainder of sentence.

This is consistent with Generic Letter 93-08.

8. Surveillance Requirement 4.3.2.3 (page 3/4 3-10) Delete phrase "shown in Table 3.3.2-3". This is consistent with Generic Letter 93-08.

Add following sentence after first sentence:

" Channel sensors are excluded from response time testing." This is consistent with NEDO-32291 as approved by the NRC SER.

9. Table 3.3.2-3 (pages 3/4 3-21/22) Delete the Table. This is consistent with Generic Letter 93-08.

10. LCO 3.3.3 (page 3/4 3-27) End LCO sentence after " Table 3.3.3-2", and delete remainder of sentence. This is consistent with Generic Letter 93-08.

11. Surveillance Requirement 4.3.3.3 (page 3/4 3-27) Delete this Surveillance Requirement.

NED0-32291 deletes the requirement to include the ECCS actuation instrument loops in response time testing. The requirement to perform response time testing on the ECCS subsystems excluding the instrument loops vill be added to the Surveillance Requirements for the TOCS' systems (LCO 3.5.1).

This is consistent vi;h the intent of NED0-32291, and with recently approved changes at Clinton Power Station.

I 12. Table 3.3.3-3 (pages 3/4 3-35/36) Delete the Table. This is consistent with Generic Letter 93-08.

PY-CEI/NRR-1932 L Attcchment 1 Page 4 of 10

13. LCO 3.3.4.2 (page 3/4 3-44) End LCO sentence after " Table 3.3.4.2-2", and delete remainder of sentence. This is consistent with Generic Letter 93-08.

14. Surveillance Requirement 4.3.4.2.3 (page 3/4 3-45) Delete phrase "si.svn in Table 3.3.4.2-3".

This is consistent with Generic Letter 93-08.

15. Table 3.3.4.2-3 (page 3/4 3-48) Delete the Table. This is consistent with Generic Letter 93-08.

16. Surveillance Requirement 4.5.1.c (page 3/4 5-4) Add new Surveillance Requirement 4.5.1.c.3 vhich states the following: " Performing an ECCS RESPONSE TIME test for each ECCS injection / spray subsystem, and verify the ECCS RESPONSE TIME is within limits. ECCS Actuation instrumentation is excluded from this test." This test fulfills the present requirement to perform ECCS RESPONSE TIME testing after removing the requirement to include the ECCS Actuation instrumentation in the response time testing. This is consistent with the intent of NEDO-32291, and with recently approved changes at the Clinton Power Station.

SAFETY ASSESSNENT Elimination of Selected Response Time Testing Requirements Regulatory Guide 1.118, Revision 2 states:

" Response time testing of all safety related equipment, per se, is not required if, in lieu of response time testing, the response time of the safety equipment is verified by functional testing, calibration checks or other tests, or both. This is acceptable if it caa be demonstrated that changes in response time beyond acceptable limits are accompanied by changes in performance characteristics which are detectable during routine periodic tests."

The analysis documented in NED0-32291 includes the identification of potential failure modes of components in the affected instrumentation loops which could potentially impact the instrument loop response time. In addition, plant operating experiences were reviewed to identify response time failures and how they were detected. The failure modes identified were then evaluated to determine if the effect on response time vould be detected by other testing requirements contained in Technical Specifications.

PY-CEI/NRR-1932 L Attcchment 1 Page 5 of 10 The results of the analysis demonstrate that other Technical Specification testing requirements (i.e., channel calibration, channel check, channel functional test, and logic system functional test) ensure that instrument response times are within acceptable limits.

These other tests are normally sufficient to identify failure modes or degradations in instrument response time and assure operation of the analyzed instrument loops within acceptance limits. Furthermore, there are no known failure modes that can be detected by response time testing that cannot also be detected by other Technical Specification tests.

A BVROG survey has concluded that instrument response time delays of 5 seconds can be reasonably detected by instrument technicians. A safety evaluation in NED0-32291 confirmed that delays of individual specific trip functions of a few seconds have very lov safety significance. This realistic bases evaluation showed that a good deal of margin exists in the licensing analysis. Within a trip function, redundancy exists in individual instrument channels (e.g., 1 out of 2 twice) and diversity exists in most safety trip functions (e.g., neutron flux, water level, dryvell pressure.). Also, for most of these instruments, the response times are insignificant compared to the safety system actuation times.

The NEDO-32291 evaluations demonstrate that response time testing can be eliminated for the following:

1) All Emergency Core Cooling System instrument loops;

2) All Isolation System actuation instrument loops except for main steam line isolation valves (MSIVs);

3) Sensors only for selected Reactor Protection System (RPS) actuation; and

4) Sensors only for selected MSIV closure actuation.

On December 28, 1994 the NRC Staff issued a Safety Evaluation Report (SER) documenting the NRC staff review of NED0-32291. The SER documented that participating utilities could eliminate response time testing in the following systems:

1. All the ECCS actuation instrumentation loops (for Lov Pressure Core Spray, Low Pressure Coolant Injection and High Pressure Core Spray systems).

2. All the Isolation System actuation instrument loops except for MSIVs (for Repctor Core Isolation Cooling, High Pressure Core Spray, Reactor Vater dean-up, Primary Containment, Secondary Containment and Residual Heat Removal (RHR) Shutdown Cooling / Head Spray).

3. Selected sensors in the RPS actuation logic (Reactor Vessel Steam Dome Pressure - High, Reactor Vessel Vater Level - Lov, Level 3, and Reactor ,

Vessel Vater Level - High, Level 8 sensors). 1 1

4. Selected MSIV Closure actuation logic (the Reactor Vater Level, Main l Steam Line Pressure - Lov sensors). The Main Steam Line Flov - High sensors were inadvertently omitted from the NRC SER, but have been  ;

i included as part of this submittal. l l

(a) Prior to installation of a new transmitter /svitch or following refurbishment of a transmitter /svitch (e.g., sensor cell or variable damping components), a hydraulic response time test (RTT) shall be performed to determine an initial sensor-specific response time value, and l-l Presently at PNPP, Rosemount transmitters are used exclusively for

! the " transmitter / switch" channels described in NED0-32291. The procedure used for Rosemount Transmitter replacement vill be revised to include a step in the prerequisites requiring a transmitter bench test for response time to be performed on applicable transmitters, prior to installation. This testing would be required whether replacing the Rosemount transmitter with a new or refurbished transmitter. The procedure vill be revised prior to the beginning l l

of the fifth refueling outage. It should be noted that NED0-32291 Appendix G also refers to Barksdale switches as included in the analyzed population of instruments. These switches are not ,

presently used in any of the PNPP applications being requested for RTT elimination. If in the future these switches are used in such an application, the appropriate changes to the installation procedures for Barksdale switches vill also be made. ,

)

(b) For transmitters and switches that use capillary tubes, capillary l tube testing shall be performed after initial installation and after i any maintenance or modification activity that could damage the lines.

I PNPP design does not incorporate capillary tubes for transmitters requiring response time testing. Therefore, this recommendation does not apply to PNPP.

As demonstrhted by the ansvers above, the plant is following the recoamendations of EPRI NP-7243.

In addition, the NRC's cover letter stated that licensee submittals must state the following in their requests:

(a) That calibration is being done with equipment designed to provide a step function or fast ramp in the process variable, All PNPP transmitters requiring response time testing are Rosemount 1153 transmitters. Existing Rosemount calibration instructions pressurize the transmitter to 125%, then depressurize the transmitter (fast ramp). During this excursion the transmitter / instrument loop l

is observed for sluggishness or arratic operation that would be indicative of degraded transmitter / instrument loop performance.

PY-CEI/NRR-1932 L Attachm:nt 1 Page 8 of 10 (b) That provisions have been made to ensure that operators and i technicians are aware of the consequences of instrument response time degradation, and that applicable procedures have been reviewed and  !

revised as necessary to assure that technicians monitor for response j time degradation during calibrations and functional tests, As stated above, PNPP procedures already include ramp change testing '

requirements to check for sluggishness or erratic operation.

Applicable personnel have been already employing these procedures in the plant. The administrative procedure which establishes the policy and administrative controls governing surveillance testing (calibrations and functional tests) at PNPP, vill be revised to include statements describing the consequences of response time degradation and need to monitor for this condition during testing.

Operators and technicians are trained to procedure changes via the required reading process. This revision vill be incorporated by the time of implementation of this Technical Specification change.,

(c) That surveillance testing procedures have been reviewed and revised if necessary to ensure calibrations and functional tests are being performed in a manner that allows simultaneous monitoring of both the input and output response of units under test, l Technicians performing calibrations and functional tests are in a position to communicate information to one another. If the technicians are in separate locations head sets are used such that ,

any observation by one technician can be communicated to the other.  ;

Existing procedures require that the technicians monitor for sluggish transmitter / instrument loop behavior while performing the ramp functions discussed above. Therefore, existing procedural requirements already meet the intent of this requirement to assure that the input and output responses are simultaneously monitored.

(d) That for any request involving the elimination of RTT for Rosemount pressure transmitters, the licensee is in full compliance with the '

guidelines of Supplement 1 to Bulletin 90-09, " Loss of Pill-Oil in Transmitters Manufactured by Rosemount," and NRC letter to licensee dated December 1, 1994 and titled " Perry Response to NRC Bulletin 90-01, Supplement 1, Loss of Fill-Oil in Transmitters Manufactured by Rosemount (TAC No. M85426)," states the NRC and its contractor have completed their review of the PNPP response to Bulletin 90-01, Supplement 1. This letter, along with enclosures (Safety Evaluation and Technical Evaluation Report '

EGG-DNSP-11516), documents NRC review and concurrence that PNPP response is acceptable and therefore in compliance with the  ;

guidelines of the Supplement.

l

l PY-CEI/NRR-1932 L Attechment 1 Page 9 of 10 (e) That for those instruments where the manufacturer recommends periodic RTT as well as calibration to ensure correct function, the licensee has ensured that elimination of RTT is nevertheless acceptable for the particular application involved. ,

l Vendor recommendations for the affected instruments listed in Enclosure 1 have been reviewed. None of the affected instruments I require periodic RTT. Therefore this recommendation does not apply ,

to PNPP.

As part of the elimination of the selected components from response time testing, it is proposed that the ECCS RESPONSE TIME test requirement be moved from the ECCS Actuation Instrumentation Limiting Condition for Operation (LCO 3/4.3.3) to the ECCS LCO (LCO 3.5.1). This change is appropriate since the ECCS actuation instrumentation loops has been eliminated from the ECCS RESPONSE TIME testing requirements per NEDO-32291. This proposal vill also change the Frequency for the Surveillance from 18 months on a STAGGERED TEST BASIS to 18 '

months in order to relate the appropriate frequency for testing the associated ECCS subsystem rather than the instrument channel. Moving the surveillance requirement from the instrumentation section to the systems section of the Technical Specifications also changes the Applicability for the surveillance requirement. Presently the Applicability (and therefore the surveillance  ;

requirement) for the ECCS actuation instrumentation for Reactor Vessel Water Level instruments is all Operational Conditions when the associated ECCS system '

is required to be OPERABLE. This proposal changes that Applicability to ,

OPERATIONAL CONDITIONS 1, 2, and 3. These changes are acceptable because there are no design basis events during OPERATIONAL CONDITIONS 4 and 5 where ECCS systems are relied upon and the response time tests, which are typically performed during shutdown conditions, would identify any operability problems that may exist. In addition, due to the pressure and temperature limitations of ,

these OPERATIONAL CONDITIONS, the probability of accidents is reduced, as is the '

need for ECCS systems to respond within the times established for OPERATIONAL CONDITIONS 1, 2 and 3. This same change has been approved for the Clinton Power Station as part of their implementation of the NED0-32291 recommendations. ,

l Relocation of Technical Specification Tables of Instrument Response Time Limits Generic Letter 93-08, " Relocation of Technical Specification Tables of Instrument Response Time Limits," provides guidance to licensees for deleting instrument response time limit tables from the Technical Specifications. provides guidance on the process to request an amendment to relocate  :

the instrument response time tables from the Technical Specifications to the '

Updated Safety Analysis Report (USAR). The changes proposed in this submittal are consistent with Enclosure 1 to the Generic Letter.

l i

l

PY-CEI/NRR-1932 L Attcchment 1 Page 10 of 10 In addition, Enclosure 1 stipulates that each licensee that wishes to implement this line item improvement should make the following commitments:

1. Licensees should confirm that the plant procedures for response time testing include acceptance criteria that reflect the response time limits in the tables being relocated. {

Existing plant surveillance instructions presently include acceptance criteria that reflect the response time limits for the tables being relocated. Modifications to these instructions is performed under the provisions of 10CFR50.59.

2. The response time limits being relocated will be included in the next update of the USAR.

The Tables being relocated vill be included in the next update of the USAR.

Generic Letter 93-08, Enclosure 2, contains examples of proposed Technical Specification page mark ups to aid licensees in their submittals. This PNPP submittal is consistent with the intent of Enclosure 2.

ENVIR0letENTAL CONSIDERATION The proposed Technical Specification change request has been reviewed against the criteria of 10CFR51.22 for environmental considerations. As shown above and in Attachment 3, the proposed change does not involve a significant hazards consideration, increase the types and amounts of effluents that may be released offsite, or significantly increase individual or cumulative occupational radiation exposures. Based on the foregoing, it has been concluded that the proposed Technical Specification change meets the criteria given in 10 CFR 51.22(c)(9) for a categorical exclusion from the requirement for an Environmental Impact Statement.
