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.

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~
