SUBJECT: CORRECTIONS TO NRC SPECIAL INSPECTION REPORT 50-361; 362/98-18
This letter responds to your letter dated February 16,1999, in which you identified several
inaccuracies within NRC inspection Report 50-361; 362/98-18. Those comments with which we
agree are incorporated into revised pages of NRC Inspection Report 50-361; 362/98-18, which
are enclosed with this letter. Please make a page-by-page replacement of the enclosed pages
with those in the subject inspection report. Those comments with which we disagree are
discussed below.
In the attachment to your letter, in reference to both the Executive Summary and
Section 08.1.b.3, you stated "The September Emergency Chiller inoperability was from
September 4,1998 rather than September 3,1998 as stated. (Please note: Section 08.1.b.1
, states correctly that the inoperability was from September 4,1998)." We disagree with this
,
statement because on September 3,1998, the chiller low temperature cutout switch was
'
inadvertently miswired, which rendered the emergency chiller inoperable. The reference to
September 3,1998, denoted the date of the error. The reference to September 4,1998,
denoted the date that the emergency chiller was declared inoperable by Operations but, in fact,
was already inoperable,
in reference to the second paragraph of Section E8.1.b.1 you stated the following:
j
-The first sentence of the paragraph describes the requirements for the use of a
nonconformance report (NCR) to accept a condition "as-is" and justify that the
configuration continues to satisfy design requirements. The paragraph goes on
to say that utilization of an NCR [rather than an Operability Assessment (OA)) in
I,'
principle, would have caused increased engineering attention to the design of the
,
chiller and the effect of the degradation on the chiller. SCE does not disagree
with the assertion that an NCR in principle would have received increased
';
attention, however, based on the conditions described in the Action Request
i
(AR) and the actions outlined in the initial Field Support assignment of the AR,
SCE believes an OA was the appropriate mechanism to evaluate the condition.
The initial Field Support assignment indicated that there was a need to have the
HVAC group investigate the thermostat setting, chilled water sensor and the
control module. Therefore, there was no intention of accepting the condition
"as-is." SCE concurs, however, that the OA was not accomplished in
accordance with Procedure SO123-XX-1 and the inadequate OA resulted in a
failure to promptly identify and correct a condition adverse to quality.

, We thank you for the above comment; however, we conclude that no correction to
Section E8.1.b.1 of NRC Inspection Report 50-361; 362/98-18 is necessary. Your comment
provides additional information that is not contradicted by the inspection report.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter will be
placed in the NRC Public Document Room.
Sincerely,
.
