Reference (a): D. B. Vassallo letter to L. DelGeorge dated March 17, 1~82.

Dear Mr. Eisenhut:

Reference (a) requested that the Commonwealth Edison Company provide, within sixty (60) days, additional information concerning ECCS outage reports for our Dresden and Quad Cities Stations. The attachments to this letter provide the requested information~

To the best of my knowledge and belief, the information contained in the attac.hments is true and· correct. In some· respects this information is not based upon my personal knowledge but upon information furnished by other Commonwealth Edison employees. Such in form a ti on has ·been reviewed in a-ccordance with Company practice and I believe it to be reliable~

Please address any further questions that you or your staff may have concerning this matter to this office.

One (1) signed original and fifty-nine (59) copies of this letter with attachments are provided for your use.

Part II - Quad Cities Station Response

PART-I

Dresden Station Response

In supplement to our previous submittal, J. S. Abel to D. G. Eisenhut dated December 31, 1980, the follo~ing information is provided in response to the Reference (a) request for additional information. Also, the ECCS equipment outage information for 1980 is provided.

In general, Dresden Station does not take ECCS systems out of service during unit operation for either surveillance testing or preventive maintenance. With respect to Technical Specification Surveillance Testing, the ECCS trains can be op~rationally tested without rendering them unavailable to perform the system design function. Additionally, preventive maintenance functions are scheduled_ and completed during refueling periods when in accordance with Technical Specifications, the:Eccs.systems are not required to b e o per a t1ona1.. . _ ~ · : ' · -. ... :.. . .

__ The.thie~ Station ~mergency'Diesel·Geneiators-represent ECCS comp·orients which '.undefrgo 'in.spection.s: an·d preventive maintenance while the reactors are ;in oper-ation. ·These procedures,_ .whit:h ·are

·based on calendar ti~e and not engine h&urs, may or may not coinside with a ~~heduled outage. The following.summary listing will show the frequency of these inspections and the approximate time the engine is out of service to complete the preventive maintenance operations~ ·

Frequency

Monthly Once per 3 months Once per 6fionths

·Once per year

Outage Time

None required 8 hours

48 hours 120 hours

Dur in· g the time period t h_a t a give n dies e 1 i s o u t o f service, no. E CCS. systems are rendered· inoperative due t 6 the d iese 1 outage. Takin~ a diesel~ut of service· is address~d by Technical Specifications.arid requires operational readiness testing of certain ECCS components, but it does not require any components to be taken out of service based solely on the Diesel Generator outage. This testing, as directed by Technical Specifications, includes daily testing of the back-up engine and all low pressure ECCS systems for the affected unit.

. -. Wa believe that clarification needs to be made with respect

to a ·5 ta temen t made in Reference (a) . Although Technica 1 Specific a-t ions will allow some ECCS components to "have substantial outage

; . ~ . . times", i.e., l of 4 LPCI pumps (3 req-uired for FSAR requirements) may be out of service for 30 days, the Technical Specification limiting conditions for operation are very specific when addressing the unavailability of any ECCS system train or subsystem. By Technical Specifications, the "unavailability" of an E CCS system train for extended periods is addressed. If any ECCS subsystem becomes inoperative power operation is allowed for the successive 7 days.

The following is a summary listing of the ECCS failures which occurred in the year 1980~

July 24, 1980 System: CCSW
