g~~~ENCLOSURE TO AEP:NRC:0773J STATUS REPORT IMPLEMENTATION PLAN OF REGULATORY GUIDE 1.97, REVISION 3, FOR THE DONALD C.COOK NUCLEAR PLANT UNITS 1 AND 2 8503050268 850228 PDR ADOCK 050003i5 l F PDR TABLE OF CONTENTS I.Background II.Status Report III.Tables IV.Footnotes AEPSC hired, in August 1984, the engineering consulting firm of DiBenedetto, Farwell&Hendricks in order to perform the detailed design study required to determine the Donald C.Cook Nuclear Plant (DCCNP)Units 1&2 compliance with Regulatory Guide 1.97, Revision 3.A final report on this subject is expected by June, 1985.This document presents preliminary findings that have resulted from our discussions with the consultant.

This report may be modified at the time we receive the final report, and for that reason we are expecting to update this status report later this year.The dates for modifications contained in this report are currently scheduled target dates.It must be recognized however, that equipment delivery delays, test difficulties, or other problems may cause delays in this schedule.Certain requirements of Regulatory Guide 1.97 were judged to be unreasonable to backfit in an operating plant.Justification is provided for these requirements to which.we take exception.

The table included with this enclosure contains information regarding instrument range, environmental qualification, seismic qualification, quality assurance, redundancy, power supply, location of display and required actions and schedule for each type A,B,C,D, and E variable listed in Regulatory Guide 1.97, Revision 3.This table is consistent in organization with Table 3 (PWR Variables) of Regulatory Guide 1.97, Rev.3 dated May, 1983.In some instances, the.Type B-E variables are duplicated by the Type A variable listing.In these instances, reference back to the Type A variable is made because the requirements for Type A variables are the most stringent.

The schedule and status for each instrument indicates when the requirements of Regulatory Guide 1.97 as described in this enclosure will be met.Open items are indicated by TBD (To Be Determined).

Deviations from the Regulatory Guide and justification for the deviations are given in the footnotes located at the end of this enclosure.

The following general notes provide clarifications for each category of information requested by section 6.2 of Supplement 1 to NUREG 0737 with the exception of instrument range, which is self explanatory:

1.Sensor Location The"sensor(s) location(s)".information requested in Section 6.2(e)of Supplement 1 to NUREG 0737 is assumed to mean the application and not physical plant location.This information i's provided in the column labeled"variable." 2.Environmental uglification Instruments reported as environmentally qualified (marked"yes" in the column labeled"EQ")are planned to meet the provisions of 10 CFR 50.49.As allowed by 10CFR 50.49(k), original DCCNP instrumentation located in a potentially harsh environment has been qualified in accordance with the"DOR Guidelines".

Equipment ordered after February 22, 1983, is to have environmental qualification in accordance with Category I of NUREG 0588 (For Comment)(i.e.IEEE Std 323-1974)unless there are sound reasons to the contrary.Consistent with 10CFR 50.49, DCCNP is not required to environmentally qualify equipment located in a mild environment.

3.Seismic uglification 4.Instruments reported as seismically qualified (i.e., marked"yes" in the column labeled"SQ")are planned to meet the provisions of the DCCNP Updated FSAR p.7.2-12 (i.e., protection grade equipment is designed such that for a design basis earthquake, the equipment will not lose its capability to perform its design objective; namely, shut the plant down and/or maintain the unit in a safe shutdown condition.)

Typical equipment of this type originally installed at DCCNP was seismically tested by Westinghouse Electric Corporation as documented in WCAP-7397-L,"Topical Report Seismic Testing of Electrical and Control Equipment".

No industry standards regarding seismic qualification existed at that time.Equipment ordered for Regulatory Guide 1.97 upgrading is planned for seismic qualification in accordance with Regulatory Guide 1.100 (i.e., IEEE Std.344-1975)unless there are sound reasons to the contrary.ualit Assurance Instruments reported as meeting quality assurance requirements (i.e., marked"yes" in the column labeled"QA")are planned to meet the provisions of the DCCNP QA program as described in DCCNP Updated FSAR Section 1.7.This program, as described, satisfies the requirements of 10CFR 50, Appendix B.The implementation of specific Regulatory Guides and ANSI standards regarding quality assurance are consistent with the commitments of DCCNP FSAR Section 1.7 Appendix A.Instruments reported as meeting the single failure criterion or redundancy requirements (i.e., marked"yes" in the column labeled"SF")are planned for a minimum of two (2)redundant, electrically independent channels up to and including any isolation device.The display may be a common multi-pen recorder or a dual indicator.

The redundant channels are also physically separated in accordance with the DCCNP Updated FSAR p.7.2-4.Physical separation requirements for redundant Post Accident Monitoring Instrumentation channels will be established in a manner consistent with the application of separation criteria to existing plant IE instrumentation 6 control circuits.The extent of conformance to Regulatory Guide 1.75 for D.C.Cook Plant IE systems was given in the answer to question 40.6 in FSAR Appendix Q, Unit 2 p.40.6-2.In some instances, redundancy will be provided by measurement of a diverse"variable.

Instruments reported as meeting Class IE power supply requirements (i.e., marked"IE" in the column labeled"PS")are planned to be powered from IE power supplies such as the 120V AC instrument buses or the 250 V DC buses as described in the DCCNP Updated FSAR Sections 8.1 and 8.3.7.Dis la Location The display will be indicated either inside the control room or at another location as permitted by Regulatory Guide 1.97.8.Schedule The implementation schedule provided for each variable is the current best estimate of the completion of the final configuration for the associated instrument including redundancy, final displays, power supplies, documentation of qualification and turnover to plant operations.

The schedules are based on anticipated delivery and plant outage schedules.

Equipment delivery delays, environmental qualification test difficulties, or other problems, however, may cause delays in these schedules beyond our reasonable control.Since the Consultant's engineering study has not yet been completed and a final report has not been issued, some items listed may require revision or deletion.In some instances equipment may be added to the list.The final configuration will not be determined until the EOP's and DCRDR program have been implemented and integrated with the Regulatory Guide 1.97 schedule.Considering these factors, our overall target date for completion of work undertaken in r'esponse to Regulatory Guide 1.97 is December, 1991.Most variables presently listed are measured with fully operational instruments, however, the instruments are not considered complete for the purposes of this enclosure until they meet Regulatory Guide 1.97 requirements as described in this enclosure.

Note that instruments previously reported to the staff as meeting the requirements of NUREG 0737 or IE Bulletin 79-01B do not, in all cases, meet all of the requirements of Regulatory Guide 1.97.The schedules provided in this enclosure for meeting Regulatory Guide 1.97 requirements are not intended to change any previous commitment regarding NUREG 0737 or 10CFR 50.49, whose requirements may be different.

I I I.-TABLES These tables represent the status of the Donald C.Cook Nuclear Plant when'e have completed all of the requirements associated with Regulatory Guide 1.97, Rev.3.It does not, nor is it intended to reflect the status of the plant as of the date of this letter.

Type A Variables: "those variables to be monitored that provide the primary information required to permit the control room operator to take specific manually controlled actions for which no automatic control is'rovided and that are required for safety systems to accomplish their safety functions for design basis accident events.Primary information is information that is essential for the direct accomplishment of the specified safety funtions;it does not include those variables that are associated with contingency actions that may also be identified in written procedures." Note: These variables are plant-specific and based on review of the D.C.Cook Nuclear Plant Emergency Operating Procedures (EOP's)plus anticipated future changes to the EOP's.The schedule and status for each instrument indicated is for when all of the requirements of Regulatory Guide 1.97, Rev 3 will be met.Item No.Purpose Variable Tag No.s Range E S Q S P Display Remarks/Action Req'd A F S Location U-1 U-2 Schedule Schedule A-1 Maintain Prcssur-Centrifigal IFI-51,52, 0-200 GPM Y Y Y Y IE Control Room Replace, control room izer Level during Chg Pump Flow 53,54 Panel SIS indicators with seismic S/G Tube rupture qualified equipment 1987 re-1987 re-fueling fueling outage outage A-2 Manual Trip of RC Pumps based on RCS pressure RCS Pressure (wide range)NPS-121,122 0-3000psig Y Y Y Y IE Control Room Replace control room 1987 re-1987 re-Panel RHR recorder with seismic fueling fueling qualified equipment outage outage A-3 NOT USFD A-4 See footnote (n)RCS Hot Leg NTR-110,120,32-700'F Y Y Y Y IE Control Room Replace recorders Temperature 130,140 Panel DTU with seismic quali-fied equipment 1987 re-1987 re-fueling fueling outage outage A-5 Set makeup for RCS Soluble automatic control Boron Concen-tration.NSX-101,103 NA NA NA NA NA NA NA See footnote (a)NA NA A-6 See footnote (n)RCS Cold Leg Temperature NTR-210>220>

In addition, since all sources of water for the safety injection system (Accumulators, Boric Acid Storage Tanks and Refueling Water Storage Tanks)are required by Technical Specifications to contain boric acid solution of a minimum concentration, the proper operation of the ECCS system ensures an adequate boron concentration in the reactor coolant to achieve and maintain the safe shutdown of the reactor core.The RCS soluble boron content is not expected to change rapidly, if at all, following the initial borating during the SI phase of an accident.Periodic analysis of RCS samples would detect any significant changes in boron concentration.

Instrumentation to continuously monitor RCS soluble boron concentration is not required since periodic analysis of RCS grab samples is adequate for verification of reactivity control.(b)Redundancy not required per NUREG 0737 requirements.(c)Seismic qualification not required per NUREG 0737 requirements.(d)All equipment is located in mild environment, therefore environmental qualification is not required.(e)Lack of lower containment spray flow monitoring instrumentation will not deter the operator's ability to determine adverse containment conditions (ACC).ACC can be monitored by looking at items such as containment pressure.If we see containment pressure conditions different than what is expected, then we can confirm whether ACC is due to a lack of spray flow by the monitoring of containment spray pump.discharge pressure.(f)The neutron flux monitors are not required for LOCA/HELB mitigation, therefore their environmental qualification is not required.Following a LOCA/HELB, reactivity control to accomplish reactor shutdown is automatically achieved and maintained by a reactor SCRAM and the injection of boric acid by ECCS.This can be verified through control rod position indications and analysis of RCS grab samples.Footnote (h)is also applicable.(g)Scheduled for upgrade as described in AEP:NRC: 0761 C (h)Instrumentation to continuously monitor RCS radioactivity is not required.Periodic analysis.of RCS grab samples is adequate to detect deterioration of fuel cladding.Indicative of an inadequate core cooling (ICC)event, fast deterioration of fuel cladding could be detected by sensing the ICC conditions through diverse instrumentation (i.e., RVLIS, CET's, TSAT meter).(i)Redundancy is accomplished by the measurement of diverse variables with fully qualified equipment.

Auxiliary Feedwater Flow is backed up by S/G level (narrow range).(j)Containment Sump Water Temperature will give no information required to mitigate and determine the consequences of an accident.Containment Sump Level, Atmosphere Temperature and pressure are adequate for operators to determine containment conditions.

Therefore, measurement of Containment Sump Water Temperature is not required.

(k)This information will be provided with our update to this report to be issued as noted in the cover letter to this enclosure.

(1)INTENTIONALLY LEFT BLANK (m)Redundancy is accomplished by verifying pump flow from qualified instrumentation.(n)This item may be deleted from the Type A variable list after further review of the DCCNP EOP's.If this occurs, the variable will be recategorized accordingly and the appropriate actions taken.The update to this report, to be submitted as noted in the cover letter to this enclosure, will reflect any changes of this nature.
