This additional flexibility is warranted since the Cook Plant design differs from the generic 4 loop westinghouse Plant and since the requiremen't to isolate the inoperable relief path (other-wise shutdown the plant)is not waived.All of the approved generic analyses remain valid for the Cook Plant even with one'ORY or BV (relief path)in-operable and isolated.There are two ways to isolate a relief path depending on whether the PORY'or the BV is inoperable. | The generic )lestinghouse analyses performed for a four loop plant include 'only two PORY's and associated BV's.

In thecase of an inoperable PORY'which cannot be restored to operable status the associated BY must be closed and power removed.In the case of an inoperable BV which cannot be restored to operable status and the BV cannot be closed or'ower removed, the associated PORV can be closed and power removed from its associated Solenoid | of one (1) PORY or BV inoperable.

In thecase of an inoperable PORY'which cannot be restored to operable status the associated BY must be closed and power removed. In the case of an inoperable BV which cannot be restored to operable status and the BV cannot be closed or'ower removed, the associated PORV can be closed and power removed from its associated Solenoid action requirements hold for all three (3) of Cook's PORY's/BV's other-Valve.'hese wise plant shutdown is required. These provisions are consistent with the model Technical Specifications contained in Mr. Eisenhut's letter. The pro-vision to close the PORV and remove power from its associated Solenoid Valve with an inoperable BY assures that the relief path once. isolated in this manner will remain isolated. Of course when testing the BY and Action State-ments 3.4.ll.a or 3.4.1l.c are applied, the provisions of 4.0.4 are no longer applicable since the preference is to keep the relief path with inoperable equipment in an isolated condition. The exemption is included in the corre-sponding surveillance requirements. | ||
As mentioned above the power supplies for the BV's and the PORY's are from the emergency buses.This is a permanent feature in the Cook Plant design.As such, the surveillance requirement for testing of.the emergency power supplies contained in Hr.Eisenhut's model Technical Specification does not apply to Cook Plant since these electrical power sources are permanently connected to the emergency safeguards buses.In order to meet the intent'of the model Technical Specification surveillance requirement we have included the provision to test the PORV's/BV's when the emergency safeguards buses are energized by the diesel generators and plant batteries in conjunction with the corresponding 18 months surveillance requirements for'this equipment. | As mentioned above the power supplies for the BV's and the PORY's are from the emergency buses.

~C-RCD Donald C. Cook Nuclear Plant Units 1 and 2 >a Docket Nos. 50-315 and 50-316 ~ca License Nos. DPR-58 and DPR-74 Lessons Learned Technical Specifications fO Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D. C. 20555
Dear Mr. Denton:
This is in response'o Mr . D. Eisenhut's letter dated July 2, 1980 proposing Technical Specifications and certain license conditions for the Category "A" Lessons Learned (NUREG-0578) requirements implemented at the Donald C. Cook Nuclear Plant.
The Cook Plant has been operating with Standard Technical Specifi-cations (STS). As such, many of the changes suggested in the model STS for the Lessons Learned items contained in Mr. Eisenhut's letter are already included in the Cook Plant Technical Specifications.
Our proposed Technical Specifications (Attachment 2 and 3) are based on revisi'ons to the existing Cook Plant Technical Specifications for Units 1 and 2 and where applicable, updated to include the scope of the Category "A" items as contained in the Safety Evaluation Report (SER) for Cook Plant compliance with the Category "A." requirements, issued on March 20, 1980. No revisions are bei'ng proposed to address wording differences or format deviations from those contained in the model STS for the Lessons Learned items.
Attachment 1 contains a brief discussion of each of the Technical Specification revisions proposed in Attachment 2 and 3. Attachment 4 contains the proposed license conditions 'for Units 1 and 2 of the Cook Plant. En all instances the content of the model STS of Mr. Eisenhut's letter was used as guidance in the preparation of the Cook Plant specific Technical Specifi'cations. oo/

Nr. Harold R. Denton AEP:NRC:00449 Director The proposed Technical Specification revisions and license conditions contained in the Attachments to this letter have been reviewed by the PNSRC and the NSDRC as required by our Technical Specifications. These reviews concluded that the proposed Technical Specification revisions and license conditions do not constitute an unreviewed safety question and will not ad-versely affect the health and safety of the public.
I8M Electric Co. interprets 10 CFR 170 as requiring that no fee accompany this submittal. 4 Very truly yours, R. S. unter Vice President cc: R. C. Callen G. Charnoff R. S. Hunter R. W. Jurgensen D. V. Shaller Bridgman NRC Region III Resident Inspector at Cook Plant - Bridgman
'l ATTACHMENT 1 TO AEP:NRC:00449 This attachment briefly describes the Technical Specification revisions contained in attachments 2 and 3 to AEP:NRC:00449. The revisions to existing Cook Plant Technical Specifications are denoted by bars in the right hand margin. The appropriate revisions to the Bases are also in-cluded in these attacj'ments. Me are ordering these Technical Specifications
~
changes in a manner consistent with the numbering of our Technical Specifi-cations.
Auxiliary Feedwater S stem S ecifications
'The following existing Technical Specifications have been revised to incorporate the automatic initiation requirements into the Engineered Safety Feature Actuation System specifications as setforth in the model Technical Specifications of Mr. Eisenhut's letter.
a} ~S ecification 3/4.7.1.2 Units 1 and 2 (Page-3/4 7-6 of both Units)
Me have removed the automatic starting signals listed under Surveillance Requirement 4.7.1.2.b re-placing them with the appropriate ESF actuation test reference to be performed under Specification 3/4.3.2.
This is in accordance with the model Technical Specifi-cations of l1r. Eisenhut's letter.
b) S ecification 3/4.3.2 - Units 1 and 2 Tables 3.3-3, 3.3-4, 3.3-5 and 4.3'-2 of both Units
. 1 and 2 have been revised to incorporate into them the automatic initiation requirements for auxiliary feedwater.
Basically, the requirements formerly in Specification
- 4.7.1.2.b have been incorporated into their appropriate section of Specification 3/4.3.2. This includes a) the LCO for the instrumentation, b) the setpoints/allowable values, where applicable, c) the system response times
'and d) the appropriate surveillance requirements.
Our existing Technical Specifications 3/4.3.2 (units 1 and 2)in-cluding the recent amendments for. "Grid Degraded Voltage" have already pui many of the AFH requirements contained in the model Technical Specifications of Mr. Eisenhut's letter into the Cook Plant Technical Specifications. As such very few revisions to these tables are necessary and are indicated oy the revision bars 'in the right hand margin of the affected pages.
0 Additionally, in Unit 1 only (Attachment 2), we have included under the Safety Injection function in Specification 3/4.3.2 the auto start requirement for the Hotor Driven Auxiliary Feedwater Pumps (NDAFP) by re-vising the heading of "Functional Unit" Section l. on tables 3.3-3 (page 3/4 3-16), 3.3-4 (page 3/4 3-24) and 4.3-2 (page 3/4 3-31) to include the l<DAFP's. This requirement is already incorporated in the corresponding existing Unit 2 Technical Specifications and they need not be revised to meet the Lessons Learned requirements.
S ecification 3/4.3.3.8 ND! - Unit 1 S ecification 3/4.3.3.6 - Unit 2 The existing Technical Specification for Post-Accident Instru-mentation in Unit 2 has been revised to include the applicable monitoring instrumentation for the Category "A" Lessons Learned items on Tables 3.3-10 and 4.3-10 and deletion of the Steam Generator wide range level indication from the same tables as a post-accident monitoring instrument. The Unit 1 Technical Specifications currently do not contain a specification for post-accident instrumentation. As such, the revised Unit 2 Specification 3/4.3.3.6 is being proposed in its entirety in Unit 1 as a new Specification 3/4.3.3.8.
He are adding this at the end of. the Instrumentation section of the Unit 1 Technical Specifications as a new item'o avoid extensive page renumbering.
The approved Cook Plant post-accident mor itoring instrumentation for the Category "A" Lessons Learned items include. (Reference 1):
a) Auxiliary feedwater flow rate channels. These channels can be substituted for by using the corresponding steam generator water level channel in the event that the AFH flow rate channels become inoperable. Both systems satisfy the Lessons Learned requirements (Reference 1).
In this case the LCO is met and no further- action is re-quired. r b) RCS subcooling margin monitor. This can be. substituted for by using the Plant computer (PRODAC-250) readout of subcooling margin in the event that the subcooling monitor becomes inoperable. Both systems satisfy the Lessons Learned requirements (Reference 1). In this case the LCO is met and no further action is required.
c) PORV position indication. The stem-mounted limit switches provide direct valve position indication in compliance with the Lesson Learned requirements. The acoustic monitoring system indication which is also installed, can be substituted for the limit switch in-dication. Both systems satisfy the Lessons Learned requirements (Reference 1). In this case the LCO is met and no further action is required.
3 & 4 0
d)'ORV block valve position indication. The stem-mounted limit swit'ches provide direct valve position iiydication in compliance with the Lessons Learned requirements.
P e)': Safety valve position indication. The acoustic monitoring system provides the direct valve position indication in compliance with the Lessons Learned requirements.
The "Steam Generator Water Level - Wide Range" channel has been .
deleted from the Unit 2 tables, and has not been included in the corre-sponding proposed Unit 1 tables for the following reasons. The Steam Generator Hide Range Hater Level (SGWRML) instrumentation does not perform any safety-related function and is not assumed operable in the various plant .safety analyses. As such, the SGWRWL Instrumentation is not included within the scope of IE Bulletin No.'9-01B. The SG Narrow Range Water Level Instrumentation (3 channels/loop) is seismically and environmentally qualified and is correctly included in. table Nos. 3.3-10 and 4.3-10. The narrow range instrumentation fulfills all post-accident monitoring require-ments for SG level indication'nd is referenced in the emergency operating procedures.
S ecification 3/4.4.4 - Units 1 and 2 The existing Technical Specification for the Pressurizer has been
. revised to include, within the Limiting Condition for Operation (LCO), the requirement for operability of at least 150 kW of heaters. This is the necessary capacity to have available within one (1) hour for maintaining adequate subcooling while'n the rratural circulation cooling mode. The existing LCO covers adequately the requirement for Pressurizer level in-strumentation since this equipment is used to verify that the Pressurizer is non-water solid by maintaining a certain water volume. The value used is consistent with that used in our proposed .over-pressurization protection Technical Specification. The corresponding ACTION of the LCO and the Surveillance Requirements have been revised to include the nevi additional requirements contained in the model Technical Specifications of Hr. Eisenhut's July'2, 1980 letter.
S ecification 3/4.4.11 - NEW - Units 1 and 2 The proposed Technical Specification for the Reactor Coolant System Power Operated Relief Valves (PORVs) and Block Valves (BVs) is a new specifi-cation for the Cook Plant. We have appropriately included this specification within the section of the Technical Specifications covering the Reactor Coolant System (3/4.4) and to avoid extensive re-numbering of existing Technical Spec-ifications we are adding it at the end of'section 3/4.4 as a new Specification 3/4.4. 11.
The Cook Plant design contains three (3) PORYs and each has a corresponding BV: The PORVs are spring-closed, air-to-open upon actuation of their corresponding solenoid control valve. The solenoid valve and the BV are electrically operated (the BV being a motor operated valve) and pow'ered from the emergency buses.
The generic )lestinghouse analyses performed for a four loop plant include 'only two PORY's and associated BV's. The proposed Action state-ment allows for operational mode changes in the Cook Plant with one (1) of the PORY's or BV's inoperable, provided of course that the relief path is Also, the reporting requirements are not applicable in the case 'solated.
of one (1) PORY or BV inoperable. This additional flexibility is warranted since the Cook Plant design differs from the generic 4 loop westinghouse Plant and since the requiremen't to isolate the inoperable relief path (other-wise shutdown the plant) is not waived. All of the approved generic analyses remain valid for the Cook Plant even with one'ORY or BV (relief path) in-operable and isolated.
There are two ways to isolate a relief path depending on whether the PORY 'or the BV is inoperable. In thecase of an inoperable PORY'which cannot be restored to operable status the associated BY must be closed and power removed. In the case of an inoperable BV which cannot be restored to operable status and the BV cannot be closed or'ower removed, the associated PORV can be closed and power removed from its associated Solenoid action requirements hold for all three (3) of Cook's PORY's/BV's other-Valve.'hese wise plant shutdown is required. These provisions are consistent with the model Technical Specifications contained in Mr. Eisenhut's letter. The pro-vision to close the PORV and remove power from its associated Solenoid Valve with an inoperable BY assures that the relief path once. isolated in this manner will remain isolated. Of course when testing the BY and Action State-ments 3.4.ll.a or 3.4.1l.c are applied, the provisions of 4.0.4 are no longer applicable since the preference is to keep the relief path with inoperable equipment in an isolated condition. The exemption is included in the corre-sponding surveillance requirements.
As mentioned above the power supplies for the BV's and the PORY's are from the emergency buses. This is a permanent feature in the Cook Plant design. As such, the surveillance requirement for testing of. the emergency power supplies contained in Hr. Eisenhut's model Technical Specification does not apply to Cook Plant since these electrical power sources are permanently connected to the emergency safeguards buses. In order to meet the intent 'of the model Technical Specification surveillance requirement we have included the provision to test the PORV's/BV's when the emergency safeguards buses are energized by the diesel generators and plant batteries in conjunction with the corresponding 18 months surveillance requirements for'this equipment.
The PORV's and BV's are just an electrical load connected to the emergency safeguards buses and, thus, the required surveillance will be performed when these buses are energized from their emergency power sources.

In addition in Unit 1 we have revised Specification 4.0.3 on page 3/4 0-2 to be consistent with 4.0.3 of Unit 2 and not require surveillance on inoperable equipment. For example, this becomes neces-sary when a relief path is isolated because of inoperable equipment, vihose operation to perform required surveillance could cause a loss of RCS pressure boundary. Performance of the BY cycling test suggested in the model Technical Specifications when the PORV in the same relief path is
.inoperable and the BV has to be closed and made inoperable {power removed)
.in accordance with the corresponding Action requirements would be undesirable since it would require re-opening that BV. As such, adding this provision
.to 4.0.3 in Unit 1 becomes necessarv and agrees wit}i 4.0.3 in Unit 2;----
Table 3.6-1: Containment'solation Valves-Units 1 and 2 A second 'fail-closed'ir operated .containment isolation valve, gCR-301, -is being installed in the letdown;line to the letdown heat ex-changer to address the NRC concern set forth in Item 2.1.4 of the Commission safety evaluation of IMECo. compliance with the Category Learned Requirements dated March 20, 1980. Technical Specification
'A'esson Table 3.6-1 of both Units 1 and 2 is being revised to incorporate 'this valve. The revision to this existing specification should become effective upon installation of the new containment isolation valve. An exact installati'on date has not been determined since this nevi equipment.
has a long procurement lead time (18 mos.). In any case, a refueling outage is required to perform this modification. The rest of the NRC-proposed Technical Specification is already a part of the Cook Plant Technical Specifications.
Table 6.2-1 -. Units'1 and 2 b
The requirement to have a Shift Technical Advisor (STA) on duty in Modes 1, 2, 3 5 4 has been included in this table on Technical Specifi-cation page 6-4 for both Units 1 and 2. A STA is on duty for both Units 1 and 2 as a shared function (appropriately footnoted) in compliance with the Lessons Learned requirements.
S ecification 6.3 Units'1 and 2 The facility staff qualification requirements have been revised to incorporate those requirements applicable to the STA. Under the approved Cook Plant STA program, full compliance with these staff qualifi-requirements will be achieved by January 1, 1981. Me propose this 'ation Technical Specification revision now {applicable to both Units 1 8 2) to take effect on 1/1/81 in compliance with the Lessons Learned requirements.
