SUBJECT:
ENVIRONMENTAL QUALIFICATION AUDIT OF THE EQUIPMENT
SUALIFICATION FILES FOR RIVER BEND STATION
,
,
Plant Name: River Bend Station
Docket No.: 50-458
Licensing Stage: OL Applicant
Responsible Branch: Licensing Branch No. 2
Project Manager:
E. Weinkam
Review Status: Review Continuing
r
~
During the week of January 28 thru February 1,1985, the NRC staff and its
.
consultants from EG&G Idaho Audited the equipment qualification files of River
'
Bend Station. The staff and its consultants audited a total of 12 files that
contained qualification information for equipment located in a potentially
,
harsh environment. As a result of the audit, the;.following are observations
and connents made by the staff and its consultants at an exit interview held
at River Bend Station on January 31,1985 (list of attendees attached).
1. A description of the River Bend Station (RBS) maintenance and surveillance -
program for all equipment within the scope of 10 CFR 50.49 must be included in
the equipment qualification (EQ) submittal.
.
2. Some parameters of concern were reviewed but were not documented by the
reviewer (e.g. leakage current on conax penetrations). The applicant must
review RBS entire EQ program to assure that all parameters of concern are
,.
adequately tested, meets the requirements of RBS, and are properly documented
<
i
in accordance with the requirements of 10 CFR 50.49.
'3. Qualification by similarity is unacceptable if the similarity analyses
does not meet the requirements of paragraph (f) of 10 CFR 50.49. The
applicant must review the RBS EQ program to identify all equipment qualified
by similart$y, and assure that qualification of the identified equipment is in
compliance with the requirements of 10 CFR 50.49(f).

4. The test reports did not always identify the tested equipment adequately,
so the applicability of the test report to plant equipment could not be
established in all files audited. The applicant must review the RBS EQ
program to assure that an auditable link has been established between plant
i
equipment and tested equipment.
The following comments are specific to individual Summary Reference Numbers
(SRN) as indicated. However, the applicants must update all files to
incorporate these comments where applicable.
(SRff-241211-1) Conax Electrical Penetration
There is no evidence in the file to indicate that a review of leakage current
has been conducted. The applicant committed to acquire leakage current data,
review it for acceptability and include it in EQ files.
(SRN-228212-1) Limitorque Valve Actuator (inside containment)
Aging calculations did not include abnormal temperature transients due to a
,
loss of off site power. The applicant committed to establish a generic
-
procedure for qualified life determination in this event. This procedure must
be included in the updated Environmental Qualification Document (EDQ)
scheduled for submittal to the NRC in February 1985. Applicant must also
notify the staff that the greese relief valves on these valve actuators are
installed correctly.
(SRN-228212-2) Limitorque Valve Actuator (outside containment with paramount
motors)
The applicant attempted qualification by two methods. The first method
-
,
attempted to establish similarity between the installed paramount motor and a
'
tested motor by another manufacturer. This approach is inadequate to
demonstrate similarity. The second method relied on a test report that had
,
,
insufficient data to show that a paramount motor was actually tested. This
was also considered inadequate. The applicant committed to demonstrate proper
qualification or replace the actuators.
^
(SRN-228218-3) Asco Solenoid Valve
During the plant walkdown it was found that the Asco valve inspected may not
be installed in accordance with the manufactureres recommendations. Applicant
must obtain installation instructions applicable to explosion proof valves and
verify proper installation.

(SRN-247481-1) Rosemount Transmitters
_
'
l
System component evaluation work (SCEW) sheets must be updated to reflect
pressure and temperature indicated in test report. Accuracy requirements on
SCEW sheet must be updated to include the actual specified and demonstrated
accuracies calculated for station requirements and demonstrated by analyses.
(SRN-247411-2) Mercury / Buchanan Terminal Boards
An auditable link between the test report and terminal boards must be
established.
In addition to the six files noted above, the following were also audited.
SRN-247529-2 Endevco Primary Position Element
SRN-241240-1 Okonite 600V Control Cable
SRN-237160-1 Westinghouse Pump Motor
SRN-211161-1 Power Systems Division, Hydrogen Igniter Assembly
SRN-SO5B
Namco Limit Switch
SRN-505A
Shaffer MSIV. Actuator

Our evaluation of the applicant's EQ program, including the results of the
audit, will be provided as input to a future SER Supplement.
