COMANCHE PEAK STEAM ELECTRIC STATION (CFSES)-

DOCKET N05 50-445 AND 50 446 L FSAR AMENDMENT 83 DESCRIPTION Gentlemen:

Amendment 83 to the CPSES FSAR was transmitted to you under a separate cover '

letter TXX 91438, dated December 20,11991. The attachment to this' letter {

.provides line-by-line descriptions of the changes-in Amendment'83. FSAR pages which do not have technical charges but are. included in the amendment.(because -

they are the opposite side of the sheet from a page that was changed,' because j the change shifted the existing material to'another page or because only *

, editorial changes were made on these pages) are not-discussed in the l= attachment.

As has been the TV Electric practice in the past.several.FSAR-amendments, 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:

justification as discussed in TU Electric letter TXX-88467 dated June 1.-1988)..

In addition, all changes applicable-to CPSES Unit 1 havefbeen reviewed under-the TU Electric.10CFR50.59 process and found not to include any "unreviewed j safety questions."

The; changes to the-quality assurance program description included or referenced ,

in the FSAR do not reduce the commitments in the program description previously accepted-by the NRC.- ~

Sincerely, J

Added low energy non Class 1E Unit 2 transformers that are loceted in the cable spreading room. The power circuits for these transformers are also routed in ex-clusive conduits, but were never reflected in.the text.

Group 3 FSAR Change Request Number: 91-096.1 Related SSER Section: SSER22 8.4.4 SER/SSER Impact: No 1A(B)-86 Dese-iption: (Revision) i exception to NRC R.G. 1.137. Section C.1 ( Section 4 of ,

ANSI N195-1976) regarding security .for the diesel-generator fuel-oil system.

Justification:

The clarification of Appendix 1A(B) for NRC R.G. 1.137 is required to be consistent with the CPSES Licensing Basis for security, based on the-following:

1) The scope-of Regulatory Guide 1.137-is to provide guidance for GDC 17 and 10CFR50. Appendix B. Security requirements of 10CFR73-are not within the scope described in the Regulatory Guide.

2) The scope of the CPSES Security Plan and the FSAR description ofLcompliance with 10CFR73 in Section 13.6-does not include Regulatory Guide 1.137 or ANSI N195-1976 as part of its licensing basis.-

3) NUREG-0797 (SSER 22) does not include Regulatory Guide 1.137 or ANSI N195-1976:as part:of the-licensing- -i basis for security.

The intent of ANSI N195 is satisf-ied by the CPSES design and administrative controls. Because the Security Plan is Safeguards Information, the: vital' equipment / vital area licensing basis should not be-described in other Licensing Basis Documents.

Replaces the Report Processor Computer (RM 21) with the upgraded Meteorological Report Processor _ Computer.(Met Computer):to enhance! system-reliability and maintenance.

-Justification:.

Meteorlogical data is transmitted to the new Met Computer wt' \ replaced the RM-21 computer (part of the Radiation hv..Itoring System (RMS)). 'The existing:

-equipment Packs and meteorologicci-system signal. cables '

were retained.-The.RM-21 was a'non-interactive, non-safety-related system that gathered meteorological. data from the Meteorological Monitoring System, averaged the-data.and printed reports on demand in a' format that. '

satisfied regulatory-guidelines. This purpose and-basic-function remains unchanged by this modification and the new computer system will continue to meet-regulatory guidelines. The removal of:the

, communication link for meteorological- data to the -RMS -

will not_ impact CPSES in generating these reports since the radio-chemistry data which are manually-inputed for' these reports are derived'from multi-channel analysis.-

Justification:

The auto-closure interlock (ACI) function of the RHR system has been . identified as a major: contributor to accidents involving loss of _ RHR cooling during non-power conditions. Westinghouse: has performed analyses to evaluate the removaloof the ACI'on a generic basis.

The NRC's safety evaluation report of'the' Westinghouse analysis (WCAP-11736)' indicated that WCAP-11736 was acceptable-for-supplementing plant specific submittals for the_ removal of_the ACI, TXX-91151 transmitted;to the NRC a request to't-evise the Technicel; Specifications associated with the

-As part of the procedural-changes' associated with-the removal of the RHR autoclosure- interlock power is .

removed from both of the RHR auction isolation valves-in each suction-line. ThisLis to provide additional assurance-that these valves <cannot be inadvertantly or spuriously opened when a potential high-to-low pressure interf ace exists-(i .e.=, RCS temperature is :above 350 degrees). ;Previously, only one. valve in each' suction:

Justification:

The circulating water bleed line to the SSW intake structure was isolated. however FSAR section was not revised. No change in performance or reliability of SSW is anticipated to result from failure to use the the circulating water makeup line. There is no concern for loss of water inventory in the Safe Shutdown Impou-ndment (SSI) as plant Technical Specification 3.7.5 provides assurance that adequate volume is maintained.

The loss of circulating water as a means to chemically treat the SSI is insignificant in that the SSW has an independent, dedicated source of chemical injection.

Jus. -' cation:

Leakage has been observed between Unit 1 and Unit 2 CCW Systems as indicated by oscillating / changing surge tank levels. This cross unit leakage has been attributed to cross unit isolation butterfly valves leaking by due to the differences in pressure between each unit's CCWS respective system portion. Cross unit leakage should be avoided as it de sensitizes the ability of the surge tank to indicate CCWS in or out-leakage. Leakage in and out of the CCWS is indicated by an increase or decrease of the tier level is the CCWS surge tank. In order to preclut. or mitigate this cross unit leakage the three 24" dia. Unit t safeguards isolation valves used for cross Unit isolation will be pulled and the piping blind flange. Also the 12" dia. SFP Cooling Heat Exchanger CCW crosstie isolation valves will be pulled and spectacle flanges installed to isolate the leakage.

Note: Removal of the 24" crosstie capabilities is an interim meaure to prevent cross unit leakage during the Unit 2 preopt test phase. Prior to unit 2 initial fuel Load the Cross Tie capability will be evaluted and restored.

Cleanup / deletion / addition of minor details on flow diagram. This is a continuation of the cleanup of mechanical systems figures provided in Amendments 81 and 82.

This figure has also been reformatted Justification:

This FSAR figure has been simplified to 1) reduce the number FSAR changas generated for revisions to minor details on flow diagrams 2) allow the use of a single set of flow diagrams for both Units 1 and 2 (except where the the Units differ) by removing Unit identifiers, and 3) improve the readability of drawings by removing non-essential detail. The changes to the figure are primarily deletions of the following types:

Line numbers (line size remains if greater than 1 inch)

Hanual valve numbers Equipment numbers for' manually operated dampers Equipment numbers (except where necessary e.g., fans and dampers Air flow rates on HVAC drawings (except fan capacity)

Drawing notes not related to system function or which are inconsequential for NRC review

This calculation evaluated the capac-ities of these systems to maintain the plant within I acceptable parameters during an ocassional extreme outdoor temperature <xcursion. The calculation utilized an extreme summer temperature of 113 deg F and an extreme winter temperature of 4 deg F.

These extreme temperatures were obtained from historical meterological data for the local area and are consistent with the meterological data presented in FSAR Section 2.3. The extreme summer temperature is being changed from 110 deg F to 113 deg F to provide additional- analytical conservatism to assure that the safety related HVAC systems are fully capable of reliably performing their intended safety function.

Justi fi cati or.:

The existing. pressure switch for this alarm is located in the dry pipe connection between the Service Water system and the Auxiliary Feedwater system. Because the system is dry, it requires venting in order to assure. functional-reliability- , The AFW pumps already-have-low suction alarm indication in the control room as part of-the normal'AFW system alarms which remains-operative should service water system backup to the AFW system be required. The dry pipe installed alarm switch duplicates this alarm and is thus unnecessary.

Relocates 4 existing, and adds 4 new, temperature elements to facilitate the detection of AFW check valve back leakage.

Justification:

The AFW check valves between the S/G and the AFW pumps can potentially leak and cause steam binding of the AFW pumps. Previously, there was one temperature element in each-of the four 4" AFW headers just upstream of the tie into the preheater bypass line. -In this configuration the existing temperature elements did not accurately reflect check valve temperature due to the temperature elements close proximity to the preheater

. bypass-line (which is at approx. 450 degrees) whereas the normal AFW check valve temperature is approximately 140 degrees. By relocating the temperature elements.

to just upstream of the check valves in the electric motor driven AFW pump supply lines and adding four additional elements upstream of the check valves in the turbine driven AFW pump-supply lines, enables the operators to more accurately assess the extent and location'of any check valve back leakage.

Add "and/or" to replace "and" in the response to 0032.110 for CIV status.

lustification:

Since some CIVs do not have control switches on the main control board, credit is taken to provide the equivelent Category 1 display required (RG 1.97 deviation limitation). However.=the response must be "and/or" on the control board to ma*.ch the as built design. The as built design satisfies the R6 1.97 requirements for Category 1 direct displays that are readily accessible and are seismically qualified from the sensor through the display.

Time delay relay ranger, Justification:

Removed the time delay range specified for the under-voltage relay, 27-2X/IEA1. This relay strips the 6.9kV motor loads from the bus upon sensing an undervoltage condition. Time delay relay ranges are shown on the 6.9kV one line diagrams in Figure 8.3 6. Removal r;f the relay range does not affect the functionability of the relay itself. Instead. it is a removal of information which is more appropriately identified elsewhere irtthe FSAR.

Description:

(Revision)

Revises diesel generatur start logic to prevent start on loss of preferred offsite power with alternate offsite power availaole and supplying power to Class 1E buses.

Justification:

On a loss of the preferred power source, if the alter-nate power source is available and powers the Class 1E buses, the diesel generator will now not start. This design modification prevents unneccesary starts of the diesel generators when they are not needed. The relay logic was changed by removing 27AX-2/ST2. which started the diesel generators on a loss of preferred offsite power. and removing the start signt from 27-2X/1EA1 and replacing it with a new time delay relay. 272X-1/

IEA1.

The new time delay relay has a delay of 1.0 sec, to allow time for the alternate offsite power source breaker to close and power the bus.

If the alternate offsite power source does not energize the bus, then the diesel generator is started and transfer made to the diesel _ generator. This design modification does not affect the start of a diesel generator on a safety

The time delay selected for the new relay remains within the allowance made for relay operation for starting the diesel generator and powering 1 4.ds useu in the accident analyses in Chapter 15 of the FSAR. In December of 1990 TV Electric filed a License Amendment Request.91-003. associated with this change. In an NRR letter dated Oct.ber 4, 1991, the NRC issued Amendt.ent 3 to the CPSES Operating Licent.e to delete the abov-start signals from the Technical Specifications. This change is intended to make the FSAR match the Technical Spec 111 cations.

Safety Classification, Seismic Category, and Quality Assurance Requirements of Valve Operators for Safety Related Valves Justification:

In the Question and Response section of the FSAR on page 260 11, the response to Question 260.1.b.25 states that " Valve operators for safety related valves are in-

cluded in the listing for the valves." Table 17A 1-does not adequately specify the defety classification, seismic category, and quality assurance requirements of valve operators for safety related valves. Note 79 has been added to Table 17A 1 where valves are listed to provide further clarification on the safe +y classifica-tion, seismic category and quality assurance require-ments. In some cases, the valve operators are not Seismic Category 1 and not subject to Appendix B quality assurance, Also, ANS! and ASHE apply only to valve operators which are integral to +he valve. The response to Question 260.1.b.25 has been updated to re-flect the addition of Note 79 to Table 17A 1.
