Licensee Action on Previous Inspection Findings
,
.(Closed) (80-35-01) MSRC QA Audit Program.. The insp'ector examine.d
' Quality Control Inspection (QCI) No. 2 "SMUD Nuclear Operations Quality -
Assurance Audit Program" and thereby confirmed that the licensee's audit-
program now includes special processes, inspections, preventative
-maintenance, document control,-records, and configuration control.
(Closed) (80-24-01) TA Procedure 19 not in conformance with Technical Specification 6.5.2.E.A.
The inspector examined Quality Assurance
Procedure QAP-19 " System Auditing", Revision 8, dated June 15, 1982. The
inspector verified that this procedure required audits of licensee conformance
to the Technical Specification and License Conditions at least once per year.

3.
Design Chanaes and Modificatian_s_
The licensee's design change program was inspected to verify conformance to
the requirements of 10 CFR 50.59 Technical Specifications, the Quality
Assurance Program, and related procedures issued by the licensee.
Selected
design change records were examined for required review and approval,
compliance with established procedures, issuance of as-built drawings
and procedure revisions (where appropriate), and evaluation of
post-modification. test ~results. The following design changes and
i
related-documents were examined during the review.
Engineering Change Notice '(ECN) A3438, resupport of RCP lube oil
-
collection system.
,
ECN, A3483, Remote jog control for DHR system valves SFV-25003 and

The inspector also examined actions taken by.the licensee in response
to commitments identified in paragraph 2 of IE Inspection Report
No. 81-37. Revision 4 to ECP-1 had been issued, and the backlog of
ECNs had been essentially eliminated.
Procedures had been revised to
provide for issuance of revised (" yellow") plant drawings prior to
placing a modified system into service. These commitments were
considered by the inspector to have been resolved.
Although yellow (temporary) plant drawings were being-issued prior to
placing modified systems into service, a backlog was apparent in getting
these drafted into permanent drawing revisions.
The licensee stated
that drafting personnel were heavily involved in TMI modifications
for the forthcoming refueling outage, and expected that they would catch
up on the drafting backlog after that time.
The inspector also made the following observations:
-
Criteria used by the Engineering and Quality Control Supervisor
in determining whether an ECN requires a 50.59 review should be
defined in pertinent procedures.
(82-40-01)
~ Incomplete closed ~50.59 review files (maintained in the QA vault)
'
-
. ere found in some' instances (copies of ECNs not included, although
w
they were available in the Site Document Control Center).
-
A sumary of the. safety evaluation was not provided for 50.59
,
changes reported in the April and May 1982 monthly reports. The
l
licensee comitted to. provide additional information by
December M,1982, as required by 10 CFR 50.59(b). (82-40-02)
A review of the ECN' log showed the backlog of design changes in progress
to be relatively small. Only a few ECNs had been under review for more
than a year.
l
No violations or deviations were identified.

IE' Bulletins and Circulars
'
The inspector verified the licensee had= received'all of'the applicable
<
.IE Bulletins and Circulars. An examination of records and discussions
with, licensee representatives verified appropriate action as follows:
'
.
..
,
,
.
.
-IE Bulletin 81-03, Flow Blockage of Cooling' Water to Safety System .
. Components by Asiatic Clam and Mussel (Closed). The inspector detennined .
that the licensee had revised surveillance Procedure SP 212.01A, Revision 7,
to require a yearly check of plant water intake-screens for evidence of
clams and muscles. This completes the' licensee's comittments described
.;
.in' inspection reports 50-312/82-22 and 82-27.
-
_
IE Circular 79-05, Moisture Leakage in Stranded Wire Connectors '(Closed).
t
'
-The inspector observed that the licensee had-detennined that this issue
was.not a problem at Rancho Seco as documented in a SMUD memo, Dieterich-
to Colombo, dated July.7, 1980. The. inspector was also informed by
-
licensee representatives that environmental qualification of cables and
-
terminations would be looked at as part of the continuing work to address
,
j
IE Circular'80-10e Failure to Maintain Environmenta1' Qualification of
5
Equipment (Closed?. .The inspector examined SMUD Memos (Raasch to
Rodriguez and Rodriguez to Raasch, both dated May 5, 1980).as well as
,
SMUD Meeting Minutes on'"79-01B Preventative Maintenance and Qualified
s
'
Life" held on October 29,1982.' Based on these meeting minutes and the
~/*
,
<
-
aforementioned memos the inspector verified that the licensee was
'
"
'
developing a list of safety related components and associated requirements.
.
, ,
'
Licensee representatives stated that this list should be' finished by .
-
,
-
Mid-1983 and would subsequently be used by the plant staff to incorporate-- . .
_
specific requirements for maintenance of environmental qualification into "
-
,

appropriate maintenance procedures.

NUREG-0588 " Interim Staff Position on Environmenal Qualification of '
'
'

Safety-Related Electrical Equipment" by June 30, 1982. Licensee personnel
also referenced 10 CFR 50.49 (47FR28363) which suspends.this requirement -

until the final rule on qualification of electrical, equipment. is published.

,
'
(Closed).
The inspector examined-the licensee's file related to thist
circular and discussed items 4.and 5 of the circular with licensee
'
!-
L
management. The licensee representatives _ stated that they recognize
'
the problem of lack of redundancy in the component cooling water system
L
and explained their plans to improve the reliability of the component
cooling water system. The licensee representatives also discussed the-
means available to monitor reactor vessel head temperature with the
inspector. The inspector concluded that the licensee's personnel were
i
aware of the concerns stated in the circular and were taking appropriate
actions.

circular. 'The inspector observed that the SMUD memo dated April l6,1981,.

This was followed on' April 9,1981~ with a SMUD memo, Rodriguez' to Raasch, . ; , 4

~

'
which; requested SMUD Generation Engineeing to get Bechtel to make the:
>
e
,,'s
above determination. On April 20,~ 1981 a SMUD Memo, Raasch to. Rodriguez,;s
,
+
requested a check to see if any relevant, reportable occurances had taken ',,
-
,
place and if so, what action was comitted to the NRC. The ~1nspector
.,
- '
discussed'this item with licensee representatives at the site who stated
>
that no'related reportable occurance had occurred and that surveillance
procedure SP201.10A requires snubbers and shock absorbers to be visually
inspected. The inspector verified the licensee's staff's statements by
<
examining procedure SP201.10A (Revision 8) and visually inspecting a
'
,
.*
sample of fifteen sway and/or support truts to verify the construction
of the bushings of these devices at Rancho Seco.
Based on these'examina-
<tions the i_nspector concluded that the licensee was adequately. aware of
the concern addressed in Circular 81-05 and because of the absence of
a discernable prcblem, the licensee's actions were appropriate.
IE Circular 81-12. Inadequate' Periodic' Test Procedure of PWR Protection
- System (Closed). The inspector examined.a SMUD Memo, Linkhart to Columbo,
dated July 30, 1981 which documented the SMUD closure of this concern.~.
The inspector verif.ied the. memo's assertions by examining the licensee's
'
surveillance test procedures for " Reactor Protection System Trips,"-
'
I-108A through D,.and Maintenance Procedure EM175. The inspector
concluded that the licensee's existing procedures adequately test each
trip function.
No violations or. deviations were identified.

on November 5 and 19,1982. The inspection findings were discussed, as set
forth in paragraphs 2-through 4.
In response to inspector comments, a
management representative stated that additional information regarding
certain completed plant modifications would be provided by December 15,
1982 (paragraph 3).
