NUCLEAR PLANT NO.2, OPERATING LICENSE NPF-21 REQUEST FOR AMENDMENT TO TECHNICAL SPECIFICATIONS TO RELOCATE COMPONENT LISTS IN ACCORDANCE

%1TH GENERIC LETTER 91-08 AND SELECTED IMPLEMIPlTATION OF THE COMMISSIO¹S POLICY STATEMENT ON TECHNICAL SPECIFICATIONS IMPROVEMENTS In accordance with the Code of Federal Regulations, Title 10, Parts 50,90 and 2.101, the Supply System hereby submits a request for amendment to the WNP-2 Technical Specifications.

Specifically, the Supply System requests revision of the WNP-2 Technical Specifications consistent with the guidance of Generic Letter 91-08.These changes will implement the relocation of component lists from the Technical Specifications.

Additionally, several of these component specific lists are part of Technical Specifications that do not meet the criteria for inclusion in the Technical Specifications as defined in the Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors as noticed in the Federal Register on July 22, 1993.These Technical Specification requirements are also not included in NUREG-1433,"Standard Technical Specifications, General Electric Plants, BWR/4," dated September 28, 1992.The identified Technical Specifications, as well as the component specific lists, are being relocated to a new plant procedure which will be controlled pursuant to the requirements of 10CFR50,59 and Technical Specification 6.8.1.The relocation of these Limiting Conditions For Operation (LCOs)is made in accordance with the Commission policy that licensees may adopt portions of the improved Standard Technical Specifications (STS)without fully implementing all Technical Specification improvements as stated in the supplementary information provided with the Final Policy Statement in the Federal Register.The Commission also stated that LCOs which do not meet any of the four criteria cited below may be proposed for removal from the Technical Specifications and relocation to licensee-controlled documents, such as the FSAR.The criteria may be applied to either standard or custom Technical Specifications.

The identified LCOs are proposed for relocation based on failure to meet the four criteria for inclusion in Technical Specifications.

26002V 9310260394 93i02i PDR ADOCK 05000397 P,-PDR 0 Page Two REQUEST FOR AMEND TO TS TO RELOCATE COMPONENT LISTS IN ACCORDANCE WITH(GL 91-08 AND SELECTED IMPLEMENTATION OF THE COMMISSION'S POLICY STATEMENT ON TSI The specific outline for Technical Specifications required to meet 10 CFR 50.36a is provided by Generic Letter 91-08.t The guidelines provided by Generic Letter 91-08 nnd the Policy Statement are followed in this change request in that the component'pecific lists, and the relocated LCOs, will be included in a plant procedure as recommended in Generic Letter 91-08.This Technical Specification amendment request includes the following proposed relocations from the Technical Specifications to a Supply System controlled plant procedure:

1)Relocation of Table 3.4.3.2-2, Reactor Coolant System Interface Valves Leakage Pressure Monitors, and the associated Action statement 3.4.3.2.d and Surveillance Requirement 4.4.3.2.3.

This relocation is performed in accordance with the Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors.Relocation of Table 3.4.3.2-2 also meets the relocation guidance of Generic Letter 91-08.This change also deletes the note at the bottom of page 3/4 4-11 since this note was only applicable until the start of the first refueling outage.2)3)Relocation of Table 3.6.3-1, Primary Containment Isolation Valves, to a plant procedure in accordance with the guidance of Generic Letter 91-08.This change includes deletion of references to this table.It also includes the addition to the Bases section the expectations for opening under administrative control.locked or sealed containment isolation valves.These expectations have been modified from the wording included in Generic Letter 91-08 to provide additional clarification relative to plant specific details.I Relocation of Technical Specification 3.8.4.1, A.C.Circuits Inside Primary Containment, in accordance with!the Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors.The listing of components in the Limiting Condition For Operation section of this Specification meets the purpose of Generic Letter 91-08 and thus could be relocated in accordance with the guidance of the Generic Letter.4)5)Relocation of Te'chnical Specification 3.8.4.2, Primary Containment Penetration Conductor Overcurrent Protective Devices, including Table 3.8.4.2-1, in accordance with the Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors.Relocation of Table 3.8.4.2-1 also meets the guidance for relocation per Generic Letter 91-08.Relocation of Technical Specification 3.8.4.3, Motor-Operated Valves Thermal Overload Protection, including Table 3.8.4.3-1, in accordance with the Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors.Relocation of Table 3.8.4.3-1 also meets the guidance for relocation per Generic Letter 91-08.

C 1 I t Page Three REQUEST FOR AMEND TO TS TO RELOCATE COMPONENT LISTS IN ACCORDANCE WITH GL 91-08 AND SELECTED IMPLEMENTATION OF THE COMMISSION'S POLICY STATEMENT ON TSI The Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors contains four criteria against which Technical Specifications are to be evaluated for inclusion in the Improved Technical Specifications.

Meeting any of the four criteria results in inclusion in the Improved Technical Specifications.

These four criteria are: Criterion 1-Installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary.Criterion 2-A process variable, design feature, or operating restriction that is an initial condition of a Design Basis Accident or Transient analysis that either assumes the failure of or prevents a challenge to the integrity of a fission product barrier.Criterion 3-A structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a Design Basis Accident or Transient analysis that either assumes the failure of or prevents a challenge to the integrity of a fission product barrier.Criterion 4-A structure, system, or component which operating experience or prob'abilistic safety assessment has shown to be significant to public health and safety.As detailed below, the Supply System has evaluated each of the proposed changes identified above per the requirements of 10 CFR 50.92 and determined they do not represent an unreviewed safety question or a significant hazard.With respect to the proposed relocation of Table 3.6.3-1, Primary Containment Isolation Valves, this change is made in accordance with the guidance provided in Generic Letter 91-08.The Supply System has evaluated this proposed change per the requirements of 10 CFR 50.92 and determined it does not represent an unreviewed safety question or a significant hazards consideration because it does not: 1)Involve a significant increase in the probability or consequences of an accident previously evaluated.

The relocation of Table 3.6.3-1 from the Technical Specifications to a licensee controlled document is administrative in nature.The surveillance and operability requirements remain in the Technical Specifications.

The Technical Specification restrictions and actions are not being revised or relaxed by this change.The accident analyses that rely on these components are not affected.Plant procedures will only be revised where necessary to reflect the relocation of the Table.Changes to the relocated valve information will be controlled and made in accordance with the administrative controls required by Technical Specification 6.8.1 and 10 CFR 50.59.Since this change does not affect the content, control, or adherence to the Technical Specification, the probability or consequences of previously evaluated accidents are not impacted.

4I , l Page Four REQUEST FOR AMEND TO TS TO RELOCATE COMPONENT LISTS IN ACCORDANCE WITH GL 91-08 AND SELECTED IMPLEMENTATION OF THE COMMISSION'S POLICY STATEMENT ON TSI 2)Create the possibility of a new or different kind of accident from any previously evaluated.

The relocation of information from Table 3.6.3-1 to a licensee controlled document serves to consolidate information on affected components.

This information will be controlled under appropriate administrative requirements.

This relocation is made in accordance with the guidance of Generic Letter 91-08.The proposed revision does not involve a change in the manner in which these valves will be operated, maintained, or tested.No components or systems are physically added, removed, or modified as a result of the proposed change.Therefore, a new or different kind of accident as a result of this change is not credible.3)Involve a significant reduction in a margin of safety.The margin of safety associated with these valves is unaffected by this proposed change since the applicable operability and surveillance requirements are not being revised except administratively as recommended by the Generic Letter.No technical changes to valve oyeration or maintenance will result due to this change.The incoryoration of this information into a new plant procedure will ensure changes are made in accordance with the controls of Technical Specification 6.8.1 and 10 CFR 50.59.The relocation of Table 3.4.3.2-2, Reactor Coolant System Interface Valves Leakage Pressure Monitors, and the associated Action statement 3.4.3.2.d and Surveillance Requirement 4.4.3.2.3, and the relocation of Technical Specifications 3.8.4.1, A.C.Circuits Inside Primary Containment, 3.8.4.2, Primary Containment Penetration Conductor Overcurrent Protective Devices, and Technical Syecification 3.8.4.3, Motor-Operated Valves Thermal Overload Protection; have been evaluated by the Supyly System against the requirements of 10 CFR 50.92.It has been determined that these changes do not reyresent a significant hazards consideration since they do not: 1)Involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed changes are consistent with the Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors.Specifically, the Specifications being proposed for relocation to Supply System controlled documents do not meet any of the four criteria specified in the Policy Statement for equipment to be included in the Technical Specifications.

Regarding the Reactor Coolant System Interface Valves Leakage Pressure Monitors, these instruments do not meet Criterion 1 since the Policy Statement specifically excludes"instrumentation to identify the source of actual leakage." These Pressure Monitors are designed to identify the source of actual leakage.

I'5 1 II Page Five'EQUEST FOR AMEND TO TS TO RELOCATE COMPONENT LISTS IN ACCORDANCE WITH GL 91-08 AND SELECTED IMPLEMENTATION OF THE COMMISSION'S POLICY STATEMENT ON TSI 2)3)The relocation of these Technical Specification requirements to a new plant procedure does not change the requirements.

The required testing and associated Actions for out of service equipment will continue to be met.The current restrictions and actions are not being revised or relaxed by this change.The accident analyses that rely on, these components are not affected.Relocation results in licensee control of future changes under the requirements of 10 CFR 50.59.Removal of the note at the bottom of page 3/4 4-11 is administrative in nature since this note was applicable only until the first refueling outage.Thus, there is no significant increase in the probability or consequences of an accident previously evaluated as a result of these changes.Create the possibility of a new or different kind of accident from any previously evaluated.

This relocated information will be controlled under appropriate administrative requirements.

This relocation is made in accordance with the guidance of the Commission's Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors.The proposed revisions do not involve a change in the manner in which the equipment will be operated, maintained, or tested, nor in the actions that will be taken should the equipment be out of service or incapable of performing their intended safety functions.

No components or systems are physically added, removed, or modified as a result of the proposed change.Therefore, this change will not result in the possibility of a new or different type of accident than those previously evaluated.

Involve a significant reduction in a margin of safety.The requested changes are not the result of a physical change to the plant or the manner in which the plant will be operated.The accident analyses for the plant as described in the FSAR are not affected by this proposed change.The operation, maintenance, and testing of equipment is not affected.Therefore, the margin of safety for the plant is not significantly reduced as a result of these changes.As discussed above, the Supply System considers that the proposed changes do not involve a significant hazards consideration, nor is there a potential for a change in the types or increase in the amount of any effluents that may be released offsite, nor do they involve an increase in individual or cumulative occupational radiation exposure.Accordingly, the proposed changes meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).

Therefore, per 10 CFR 51.22(b), an environmental assessment of these changes is not required.The approved amendment will be implemented within thirty days of receipt.Numerous proc u rocedural changes will be required to delete the reference to the Technical Specification requirements that will be relocated by this request.Since the Technical Specification requirement relocation does not result in a change in requirements, the resulting reference changes in the procedures will be treated as administrative in nature and will be made at the next C ill Page Six REQUEST FOR AM~22lD TO TS TO RELOCATE COMPONENT LISTS IN ACCORDANCE WITH GL 91-08 AND SELECTED IMPLEMENTATION OF THE COMMISSION'S POLICY STATEMENT ON TSI available opportunity.

Special procedure revisions to delete reference to the relocated Technical Specifications will thus not be made.As stated above, the specified testing will continue to be performed at the current periodicity with any future changes to these requirements made per the requirements of 10CFR50.59.

This Technical Specification change has been reviewed and approved by the WNP-2 Plant Operations Committee and the Supply System Corporate Nuclear Safety Review Board (CNSRB).In accordance with 10 CFR 50.91, the State of Washington has been provided a copy of this letter.V ery yours,.Parrish, Assistant Managing Director, Operations DAS/ds Attachments CC: BH Faulkenberry

~k~)o Should it be necessary to make the suppression chamber inoperable, this c~~~shall only be done as specified in Specification 3.5.3.Under full power operating conditions, blowdown from an initial suppres-sion chamb w temperature of'90 F results in a water temperature of approxsmatel 135'F immediately following blowdown which is below the 200'F used for comp e e condensation via quencher devices.At this temperature and~atmospheric pressure, the available NPSH exceeds that required by both the RHR and core spray pumps, thus, there is no dependency on containment overpressure during the accident injection phase.If both RHR loops are used for contain-ment cooling, there is no dependency on con ainment overpressure for post"LOCA operations.

Experimental data indicate that excessive steam condensing loads can be avoided if the peak bulk temperature of the suppression pool is maintained below 200'F during any period of relief valve operation with sonic conditions at the discharge exit for quencher devices.Specifications have been placed on the envelope of reactor operating conditions so that the reactor can be depressurized in a timely manner to avoid the regime of potentially high suppression chamber loadings.Because of the large volume and thermal capacity of the suppression pool,~t the volume and temperature normally changes very slowly and monitoring these arameters daily is sufficient to establish any temperature trends.Ey requiring the suppression pool temperature to.be frequently recorded during periods of significant heat addition, the temperature trends will be closely followed so that appropriate action can be taken.The requirement for an external visual examination following any event where potentially high loadings could occur provides assurance that no significant damage was encountered.

In addition to the limits on temperature of the suppression chamber pool water, operating procedures define the action to be taken in the event a safety/relief valve inadvertently opens or sticks open.As a minimum this action shall include: (1)use of all available means to close the valve, (2)initiate suppression pool water cooling, (3)initiate reactor shutdown, and (4)if other safety/relief valves are used to depressurize the reactor, their discharge shall be separated from that of the stuck-open safety/relief valve to assure mixing and'uniformity of energy insertion to the pool.3/4.6.3 PRIMARY CONTAINMENT ISOLATION VALVES B.3/4 6-4 The OPERABILITY of the primary containment isolation valves ensures that the containment atmosphere will be isolated from the outside environment in the event of a release of radioactive material to the containment atmospheie or pressurization of the containment.

'I)~J lg CMTAINMENT SYSTEMS.CONTROLl.ED COPY BASES 3/4;6.4 VACUUM RELIEF Bm Vacuum relief breakers are provided to equalize the pressure between the suppression chamber and drywell and between the reactor building and suppres-sion chamber.This system will maintain the structural integrity of the primary containment under conditions of large differential pressures.

The vacuum breakers between the suppression chamber and the drywell must not be inoperable in the open position since this would allow bypassing of the suppression pool in case of an accident.There are nine pairs'of valves to provide redundancy and capacity so that operation may continue indefinitely with no more than two pairs of vacuum breakers inoperable in the closed position.3/4.6.5 SECONDARY CONTAINMENT Secondary containment is designed to minimize any ground level release of'adioactive material which may result from an accident.The reactor building and associated structures provide secondary containment during normal opera-tion when the drywell is sealed and in service.At other times the drywell may be open and, when required, secondary containment integrity is specified.

Establishing and maintaining a vacuum in the reactor building with the standby gas treatment system once per 18 months, along with the surveillance of the doors, hatches, dampers, and valves, is adequate to ensure that there are no violations of the integrity of the secondary containment.

The OPERABILITY of the standby gas treatment systems ensures that suf-~ficient iodine removal capability will be available in the event of a LOCA.The reduction in containment iodine inventory reduces the resulting SITE BOUNDARY radiation doses associated with containment leakage.The operation of this system and resultant iodine removal capacity are consistent with the assumptions used in the LOCA analyses.Continuous operation of the system with the heaters OPERABLE for l0 hours during each 31 day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters.3/4.6.6 PRIMARY CONTAINMENT ATMOSPHERE CONTROL The OPERABILITY of the systems required for the detection and control of hydrogen gas ensures that these systems will be available to maintain the hydrogen concentration within the primary containment below its flammable limit during post-LOCA conditions.

Either drywell and suppression chamber hydrogen recombiner system is capable of controlling the expected hydrogen generation associated with (1)zirconium-water reactions, (2)radiolytic decomposition of water, and (3)corrosion of metals within containment.

The hydrogen control system is consistent with the recommendations of Regulatory Guide l.7,"Control of Combustible Gas Concentrations in Containment Following a LOCA," September 1976 Amendment No.100 T'ai>sec 7iotl sk tl Le~~ver++a.tlecu P~ga.5>//8-g<<~A~revePse.s'le oF this j'4g~WASHINGTON NUCLEAR-UNIT 2 B 3/4 6"5 l,~" a S'I t 0 PRIMARY CONTAINMENT ISOLATION VALVES (Continued)

The opening of locked or sealed closed (i.e.manual)containment isolation valves on an intermittent basis under administrative control includes the following considerations: (I)stationing an operator, who is in constant communication with the control room, at the valves, (2)instructing this operator to close these valves in an accident situation, and (3)assuring that environmental conditions will not preclude access to close the valves and that this action will prevent the release of radioactivity outside the containment.
