Licensee Action on Previous Inspection Findings
(0 pen) Noncompliance (358/79-13-16):
Specification of Env._ nmental
Requirements for Gaskets, Sealants, etc. in HVAC systems.
Sargent &
Lundy issued Supplement 3 dated August 3, 1979 to Specification H-2298
for HVAC ductwork with the radiation dose requirements. However, the
temperature and humidity requirements, which these material will be
subjected to in addition to the radiation, specified in pages 3-11-12
through 3-11-14 of the,Zimmer FSAR are not reflected in Revisison 3.
The additional information provided consisted of the following documents:
1.
Literature from DuPont elastomers stating the thermal resistince of
Neoprene.
2.
A letter from Goodyear Tire and Rubber Company to S & L st. ting the
cht.racteristics of style E diaphram, on which irradiation tests were
not performed. The lettey indicates the results of a sir.ilar EDPM
compound tested at 5 x 10 trads.

The licensee stated Gat the specification will be revised to reflect
the temperature au m idity requirements and would obtain from the
manufacturer the maionship between EPDM compound and 'E'
style
diaphram.
(CloseO Noncompliance (358/79-13-02): The inspector reviewed Weld
Procedure Specification (WPS) PQW-33 approved by S & L on June 1, 1979
which qualifies welding A527 type material to A-240 using AWS#RCuSi-A
type electrode. Tests performed by Patzig Testing Laboratories indicate
that the WPS meets the requirements of 1974 edition of the ASME Section
IX.
Inspection of these welds is not complete as work is being
accomplished in other areas.
(Closed) Item of Noncompliance (358/79-13-03): Failure to perform audits.
The inspector reviewed a corporate audit perfo 1ned by the Waldinger
Corporation, Des Moines, on their site office during June 13, 14 and 15,
1979 to verify the implementation verification of the Quality Procedures.
Four audit findings were identified relative to approved vendor's list,
controlability of the Construction Manual, alignment inspection of installed
rotating equipment and inspection requirements for equipment placing
(hanging) and setting.
Corrective action taken was verified and signed
off as complete on all four findings prior to July 18, 1979.
(Open) Unresolved Item (358/79-14-01): Additional information from the
manufacturers of HVAC equipment was being collected to prepare checklists
to verify the adequacy of the installation. The contractor requested the
licensee to provide acceptance criteria. Pending receipt of the infor-
mation and development of an acceptable checklist, this item remains
open.
(Closed) Unresolved Item (358/79-16-02): The floor above the switchgear
room adjacent to the control room was observed to have dust paricles and
Zonalite. Corrective action taken is considered inadequate, and this
unresolved item is escalated to an item of noncompliance, a deficiency,
housekeeping conditions adverse to quality contrary to the requirements
of 10 CFR 50 Appendix B Criterion XIII.
(358/79-28-01)
(Closed) Unresolved (358/79-14-03): The certificate of conformance
supplied by ACS Industries, the supplier of the moisture separators for
the Essential Filter Packages did not address the requirements of
paragraph 203.2.C.
S & L Design Document change #SLM-498 dated May 30,
1979 deleting this requireme .t; justification was tha: 203.2.C far exceeds
the actual design requiresents that essential moisture separators will be
subjected to during abnarmal operating conditions.

.
(Closed) Unresolved (358/79-16-05): A program was to be developed and
implemented by Powers Regulator to inspect the compressed-air lanes
installed by them which are attached to safety related systems to preclude
damage to the safety related systems during installation. The licensee
in a letter dated June 15, 1979 requested MCC Powers (Powers) to submit
as-built drawings to S & L for approval. Discussion with Powers' Site
Manager indicates that Tubing / Tray Installation procedure #QAP526 is
under preparation and a system walkdown will be performed to confirm that
their installation is in accordance with their as-built drawings and
p'rocedure .
(Closed) Unresolved (358/79-16-06): The details on mounting of the
Radiation Sensors - RelD13N009B and RE1D1BN019B to meet Seismic Category
I requirements has been finalized in Design Drawing Change (DDC) #SLS-349
and drawing M559 Revision 6, respectively. The sensors are in storage
since they contain radioactive elements.
Functional or Program Areas Inspeciqd
1.
Observation of HVAC Hanger Repairs
The inspector reviewed the pregress of the corrective action being
taken bv Walding, Young & Bertke (WYB), the HVAC contractor, to
repair the nonconformances identified on the hanger supports. This
work is being accomplished by working in designated areas.
The
inspector reviewed selected Nonconformance Reports on which correct.ve
action was completed and verified that the completed work was satis-
factory. The inspector also observed the work in progress and
det rmined that applicable procedures were being followed.
The following hangers at elevation 546' in the proximity of the
a.
control room as indicated in drawing 514-5 required additional
Everdur and reinforcement on welds.
Corrective action taken
was verified to be complete and satisfactory.
(1) Hanger #2020 - Inspection Report (IR) I#21
(2) Hanger #2011 - IR#22
b.
During the inspection, corrective action vas being taken on the
hanger #2022, IR#I-73, at elevation 546' in the control room
vicinity. Clips which had not been installed on the hanger
legs as shown in drawing M514-5 were being corrected. Weld
Procedure Specification (WPS) JW1-28 Revision 2 was specified;
as specified, Shield Metal Arc Welding process was being used
with 1/8" diameter E-6011 type weldrod.
Subsequently, documenta-
tion on the qualification of the weldor who was performing the
weld and the weldrod withdrawal wa. verified and determined to
be acceptable.

c.
The inspector observed installation of hangers #2190 and 2195
in progress; the hangers are identified in drawing #M513-6.
Design Drawing Change (DDC) WYB-600 which identifies the
modifications to the hangers was being implemented. Welding
was being performed to the requirements of WPS W1-28 Revision
2; SMAW process with 1/8" and 3/32" diameter E6010 type elec-
trodes were being used. Subsequently, the inspector reviewed
.
documentation on the weldor qualifications and weldrod withdrawal
..
and determined it to be acceptable.
d.
The inspector reviewed NCR#FI-1A dated May 22, 1979 which
identifies that one nut was tissing on the support structure
for secondary containment iso ation damper IVG03YB identified
on drawing M513-6. The inspector independently verified that
the bolt has since been replaced. The NRC remains open pending
reinspection.
2.
Unacceptable Housekeeping Conditions
Unresolved Item 378/79-14-02 identified during an inspection in
May 22-24, 1979 identified unacceptable housekeeping conditions on
the false cei'ing of the switchgear room adjacent to the control
room. The inspector was assured that these conditions would be
corrected. On September 10, 1979, the inspector observed the following
conditions.
Considerable sandlike dust disintegrated from Zonolite flooring
a.
was on the floor.
b.
Miscellaneous construction debris mainly consisting of insulation
removed from installations were scattered on the floor.
c.
Welding activities were being performed by HVAC and electrical
contractors without' adequately protecting the installed safety
related cables.
The licensee and contractor personnel acknowledged the adverse
housek2eping conditions. The inspector expressed concern that the
above unacceptable sonditions could adversely affect the operability
of the equipment installed in the control room due to a construction
opening joining the false ceiling to the control room. The inspector
informed the licensee that this previously identified unresolved
item is being escalated to an item of noncompliaace, contrary to the
requirements of 10 CFR 50 Appendix B, Criterion XIII.
(35S/79-28-01)
The licensee acknowledged the findings and initiated corrective
action to clean the area, to block the construction opening and
review the cleanliness of the installed panels in the control room.
