$UBJECT: COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)

DOCKET NOS. 50 445 AND 50 446 FSAR>AMEhDMENT 79 DESCRIPTION Gentlemen:

Amendment 79 to the CPSES ESAR was transmitted to you under a separate cover letter TXX 90222, dated Juiy 31, 1990. The attachment to this letter provides

• line-by-line descriptions of the changes in Amendment 79. FSAR pages which do not have technical changes but are included in the amendment (because they are on the opposite side of the sheet from a page that was changed, because the change shifted the existing material to another page or because only editorial changes were made on these pages), are not discussed in the attachment.

All~ changes described in the attachment have been evaluated for relative significance (i.e., the group number'1, 2, 3 or 4.following each' change ,

,iustification) as discussed in TV Electric letter TXX-88467, dated June 1, 1988. In addition, all changes affecting Unit 1 (but not necessarily changes which affect Unit 2 only) have been evaluated under the TU Electric

'" 10CFR50.59 evaluation process.

' Included in this amendment are:

1. Revisions, clarifications, corrections and updates to text, tables and figures.

2. Several updated FSAR mechanical systems flow diagrams on which excessive detail was removed as previously' discussed with the NRC and as referenced in NRC letter dated May 15, 1990. The remaining mechanical systems flow diagrams willibe updated in a similar manner in future amendments.

3. A number of responses to NRC questions (currently located in the 0&R section of the FSAR) have been relocated to FSAR text, tables or l figures in preparation for converting the FSAR into an Updated Safety Analysis Report (USAR). This process is expected to be I ongoing for the next several amendments until all responses have l been relocated. The relocated Q&R responses are revised using words-similar to "See FSAR Section (3.2.2), or revised FSAR Section (3.2.2)", depending on whether the response already exists in the .

FSAR, or needs to be relocated to the FSAR. A O&R reference is usually added to the margin adjacent to the FSAR paragraph. '

containing the Q&R response.

4. A. revised Effective Page List updated through Amendment 79.

Description:

-(Correction)

Correct schedule for monthly c.perating report.

Justification:

The Monthly Operating Report is required to be submitted by the 15th of each month pursuant to Specification 6.9.1.5. This chriges the FSAR to be consistent with the Tech. Spec, coquirements.

Description:

(Revision)

Revise Steam Generator Power 0perated. Atmospheric Relief Valve Capacity Justification:

The as-designed relief valve capacity has been changed.

The capacity has been changed to allow sufficient mar-gin to meet the minimum and maximum values in the cur-rent accident analysis and plant cooldown analysis, respectively. The change to the FSAR also provides the basis for the capacities in more detail than before.

Group: 2 FSAR Change Request Number: 90-131.3 SER/SSER Impact: No 1A(B)-51

Description:

(Revision)

For clarity and consistency with the revised cable separation criteria, the discussion of " equivalent" raceway, enclosures and wraps is consolidated into a discussion of " acceptable barriers"_.

Justification:

For clarity and consistency with the revised cable separation criteria, the discussion of-" equivalent" raceway, enclosures and wraps is consolidated into a discussion of " acceptable barriers". For the same reasons, equipment and device enclosures and enclosed-metal wireways inside equipment are now specifically mentioned as " barriers".

Group: 2 FSAR Change Request Number: 90-091.3

-Related SER Section: 8.4.4: SSER22 8.4.4 SER/SSER Impact: Yes Although equivalency of these " barriers" is discussed in SSER 22. Section 8.4.4, they are not referred to as barriers.

Description:

(Revision)

Revises design basis groundwater elevation for the mn service water intake structure (SWIS) from 780' to 793'.

Justification: ,

The highest and lowest groundwater level a'djacent to the SWIS were reported to be 783' 2" and 782'-3",

respectively, during 1988. Considering the maximum fluctuation in the groundwater elevation expected over; the 40 years life of the p'. ant, the SWIS has ,

been reanalyzed using a c>nservative groundwater elevation _of 793', which is the probable maximum flood

. (PMF) level-for the Saft. Shutdown Impoundment including L wave run up at the SWIS. This envelopes the highest E groundwater level expected for the life of the plant.

Group: 2 FSAR Change Request Number: 90 052 Related SER Section: 2.4.6 SER/SSER Impact: Yes-The design basis ground water elevation for the service water intake structure should be revised from 775 to-793, l

Description:

(Revision)

Simplified criteria for cable and raceway separation-at CPSES based on existing docketed testing and ,

supplemental analysis.

Justification:- <

Since it was approoched on a case by case basis on

, Unit 1, the cable separation criteria for CPSES became L complicated, with lengthy and detailed inspection criteria. This change simplifies the cable and raceway separation criteria by expanding the 1 barrier and 1"-

l- criterion to cover power tray separation and conduit l- separation above a tray or cable. The revised criteria  ;

are based on testing already docketed for CPSES with ,

appropriate supplemental analysis. The separation 1 criteria based on testing and analysis meet the requirements of Regulatory Guide 1.75, Revision 1.

The discussion of separation caiteria has been.

rearranged and editorial corrections made for clarity ,

and to consolidate the discussion.

To minimize future complications to the criteria, ,

included in the revision is a discussion of the- '

minimum distances demonstrated by the existing test data. These distances would be used to evaluate any conditions found or encountered in construction where it is not practical to meet the more conservative minimum separation crituta due to. actual plant conditions. These cases would be documented in accordance with site procedures and, if found accept-able based on the testing and analysis described in the FSAR, will be in compliance with Regulatory Guide 1.75.

Revision 1.

The revised criteria have been evaluated under-10CFR50.59-and been found not to be an Unreviewed Safety Question.

The revised criteria will be applied te b_oth Unit 1 and Unit 2 as of the date of the advance amendment (TXX-90229 dated June 28, 1990) and will be used for the walkdown: in Unit 2.

Adds supplemental information to criteria for loading l cable' trays'above siderails.

Justification: l As requested by tne NRC and described in TV-Electric l letter 10gged.TXX-90025, dated January 17, 1990, i supplemental information is added to the description of- l criteria for loading cable trays above siderails.. l

(:

This change provides the results of a one time' review of Unit I made at the request of the NRC to identify, l& where cables extend above'the top of Class IE cable-tray siderails and exceed the percent fill limit and' l

, can not be corrected by reasonable means. TV Electric recognizes the.need to minimize the number of cases where cables extend above the top of Class 1E cable tray siderails and exceed the percent fill limit and. l

[_ has implemented measures to control future installa- i' t -tions such that additional instances will only be l inplemented subsequent to evaluation by TU Electric.

(Correction) I Delete the interlock between supply f ans CPX VAFNAV-23 and 24 with exhaust fans CPX VAFNCB 21 and 22 in the Primary Plant Ventilation system. l Justification l The primary plant exhaust fans CPX VAFNCB 21 and 22 and I associated fans were upgraded to ESF status to provide additional capability.of the PPVS to maintain slight negative pressure in the negative pressure ravelope.

Earlier, these fans were interlocked with non ESF sup- I ply fens CPX VAFNAV 23 and 24, respectively. During the I operation of ESF exhaust fans, operation of non ESF 1 exhaust fans are not required to maintain negativa pressure in the negative pressure envelope. Hence, the I interlock has been removed from these two fans.

The removal of interlock allows the supply fans to be utilized as standby supply fans. If any other supply f an is down for maintenance and additional cooling is required, these fans could be started, as long as the negative pressure is maintained. 4 The removal of interlock may affect the negative pres-sure requirements in the case when these fans are oper-ating and a loss of Offsite Power occurs. This trips all the exhaust units and all those interlocked supply ,

f ans. If either of these supply f ans were in operation, the negative pressure may be affected in the short run, however, the operator may manually energize one or more of the ESF exhaust fans after 120 seconds to achieve and maintain slight negative pressure in the envelope. Appropriate plant documents have been revised to provide a system limitation and precaution to operate these supply f ans.

1 Feedwater Isolation Valve (FIV) Actuation Logic Modification of Low Flow Interlocks Justification:

The opening of the FIV causes a momentary flow insta- t bility during wh:ch the feedwater flow may decrease be-low the Low Flow closure setpoint. The logic automat-ically shuts the F4V. The modification changes the logic so that the FlV will not shut on feedwater low temperature alone, but will shut the FIV when the feed-water low flow is coincident with feedwater low temper-ature.

Delete the automatic control function of the flow control valves of the motor driven auxiliary feedwater pumps.

Justification:

Automatic control of the flow control valves is provi-ded to prevent pump runout. During hot fun'tional testing, both motor driven pumps were tested on SI signals, with the steam generators depressurized, for flow criteria and pump runout. The test results indica-ted that the pump runout controls were not required be-cause the piping system provided sufficient resistance to prevent pump runout conditions. Deletion of this requirement does not impact any system requirements and simplifies the system design.

Justification:

The analysis has been completed. The results indicate that the HELB from the SGB piping break would not-impact the habitability of the Control Room.

From the HELB analysis in FSAR Section 's.ti.1. the following design modifications were instituted: addit-ion of dampers in ventilation ducts connecting to Room 113 to prevent steam flow through the ventilation leak-age path to surrounding areas (including the stairwell which leads to the Control Room): and a door j modification to keep steam f rom entering the l stairwell through the doorway ( the door now opens into

• - the door to push against the seals.)

These modifications prevent significant amounts of steam from entering the stairwell and also limit the J

pressure in the stairwell to levels.that are too low.to unlatch the Control Room doors. The Systems Inter-u action calculation (SI-CA 0000-997, rev. 0) assumes, in

.the worst case, that the dampers remain open during the HELB, The calculated pressure increase in the stair-well is 0.254 psi. A Gibbs & Hill letter'(GTN-60131),

which provides the results of a pressure test on the

, doors, indicates that-the BRINKS latches used on the security doors do not unlatch until the pressure -

l differential exceeds 1.1 psi. In addition, the Control y Rcam is routinely maintained at a slight positive H pressca (0.125-in wg), the joints-and penetrations

Justification:

The note is added to show that appropriate guidance is provided to operations in the applicable emergency i operating procedure for this scenario.-The procedure ,

provides that if offsite power is not available, j necessary measures-are taken for early restoration of power to the battery charger for the batteries which  !
