Licensee Action on Previous Inspection Findings
2.1 The discrepancies identified in Inspection Report 85-15 continued
from Unresolved (354/84-10-01) Seismic II/I Program are related to
inconsistencies contained in the documents controlling the walkdown
and QC inspection of activities associated with the Seismic II/I
Program. Based on discussiens with cognizant licensee and engineer
representatives and a review of procedures, the following are satis-
factory resolutions to specific parts of this item. The parts are
listed in the same order that they were identified in report 85-15.
Unresolved Item (354/84-10-01)
part No.
Resolution and Closecut
-
3.
The spacing of supports for non-category I ductwork are required
to be controlled by QC instruction SM-1.03-1.
The support
spacing shown on drawings for Non-Q ductwork is the result of
engineering design which is a "Q" item. This precludes the
possibility of ductwork collapse during an SSE event due to
excessive support loads.
4.
The inconsistency between specification G-052 and design cri-
teria D7.9 is removed in Addendum 1 to Revision 2 of the latter
which deletes section 7.1.3.
5.
The generic exemption from QC involvement in Seismic II/I
interactions contained in Specification G-052 section 2.3.6 has
been deleted in Addendum 3 to Revision 2 as a result of
completed calculations.
7.
The clarification of Specification G-052, paragraph 3.5.2b is
provided in Revision 2 and in Addendum 2 to paragraph 2.4.2,
10. The incorporation of commitments on adequacy of non-safety con-
duit clamps / raceway supports is provided in Specification G-052,
Addendum 2 to Revision 2 and in design criteria D7.2, Revision
5.
11. Design criteria 07.2 Revision 5 now agrees with G-052 on re-
quirements for sampling inspection for generic acceptance by QC
of certain !!/I items.
12. The calculations to substantiate exemptions from seismic II/I
are now complete. They substantiate the exemption identified
in Specification G-052 paragraph 2.3.6.
13. Addendum 3 to Specification G-052 Revision 2 provides consis-
tency with design criteria 07.3 paragraph 4.4.1.f regarding
exemption of ladders and handrails from Seismic II/I concerns
and QC inspection thereafter.

14.
The inconsistency between the design criteria and the specifi-
'
cation regarding areas inside the plant not containing safety
related equipment has been resolved by Revision 2 to 07.9 which
incorporates Specification G-052 Section 2.1.3.
This revision
and the qualification of Non-Q ductwork as identified in Part 3
resolves this item.
r
15.
The adequacy of non-seismic raceway installations / support
spacing - is resolved by engineering design of non-seismic
raceway supports and QC inspection as addressed in item 3 and
14.
16.
The discrepancy regarding spacing of "Q"-tray supports in D7.9
l
and Specification J-825 is resolved by Revision 2 Addendum 1 to
07.9 which deletes reference to J-825 and adds:
Routing of
instrument impulse lines are not to be considered as a II/I
'
hazard.
17(a) The instrument drawing identification implies that QC inspection
is required.
17(b) Regarding tubing support installation Addendum 1 to Revision 2
provides consistency between 07.9 and G-052 paragraph 3.34 to
adequately resolve this item.
,
The above parts of UNR 84-10-01 together with the parts found
i
acceptable in inspection report 85-15 closes UNR 84-10-01.
2.2 (Closed) Unresolved item (85-15-01): HVAC ductwork/QC inspection for
dents and wrinkles at time of installation. Ductwork buckling of
5/8" at mid-distance was investigated by Bechtel engineering for its
effect on airflow and pressure. The inspector discussed the calcula-
,
l
tions with cognizant site engineers.
The effect of reduced duct area
'
due to the 5/8" buckling was found not in excess of the allowable
balancing latitude for achieving the required airflow. Additionally,
specification M-735 Change Request No. M-703, dated January 17, 1984,
regarding conditions for acceptance of minor dents or wrinkles on
installation, states that acceptance for installation of the duct
(minor dents or wrinkles) will be by field engineering. Also M-735,
section 7.3.2 on ductwork construction workmanship allows waviness
or bulging of rectangular duct sheet plates of up to i h-inch per
4 ft section.
.
2.3 (0 pen) Unresolved items (85-15-02) and (85-15-04) - These remain
open pending receipt at the site from San Francisco of calculations
'
and subsequent NRC review.

2.4 (Closed)Unresolveditem(85-15-03) Control of scaffolding erected in

contact with HVAC ductwork and hangers. Bechtel field construction

tendents to prevent erection of scaffolding or rigging in contact
with HVAC ductwork without approval of field engineering. The
instruction provides for disciplinary action up to termination for
personnel violating the directive.
No violations were identified.

Document Review and Walkdown Inspection of Seismic II/I Program
A walkdown inspection was performed of a completed seismic II/I evaluated,
safety-related structure.
The purpose of this inspection was to verify
II/I documentation.
The intent was to see that safety related structures
outlined in Regulatory Guide 1.29 will not be prevented from carrying out
their functions by physical interactions with non-seismically qualified
elements as a result of an SSE event.
One of four cells of the Diesel
Generator Building (DGB) structure was selected for detailed review and
inspection of 17 items required to be evaluated for the following actions:
Rework by construction
-
Inspection by QC
-
Verification by the II/I team
-
The inspector observed and discussed with the cognizant II/I group leader
four non-seismically qualified items contained in Cell 8 of the DGB, which
required inspection by QC.
No additional items were identified as a
result of the evaluation of these items to ensure that no adverse inter-
action could result from a seismic event. Also no additional items were
identified as a result of the final II/I walkdown.
The inspector's record
review of the other three diesel generator cells and their item of II/I
significance disclosed no discrepancies.
No violations were identified.

4.
Licensee Surveillance / Audit Activities
Documentation of licensee surveillance activities pertaining to
insulation work by Owens-Corning Fiberglas Corporation for the reactor
pressure vessel and drywell piping was reviewed by the inspector.
First
line inspection of this work is the responsibility of BpC.
The PSEG
records provide evidence that the licensee has maintained continuous
surveillance of the work from its inception in May 1984 to the present.
Documentation of licensee audit activities pertaining to the seismic II/I
evaluation program were also reviewed.
The annual audits initiated in
February 1983 use check lists, address unresolved items and are responded
to by BPC. The resolution /closcout of UNRs is contained in the documents
reviewed.
No violations were identified.

Heave / Settlement Measurement Program - Review of Annual Report
The inspector reviewed BPC's settlement plots and plots of differential
settlement (at the powerblock) measured at six month frequency up to
October 18, 1984. This report identifies measurements taken after the
start of dewatering in March 1983 and its termination October, 1983. A
review of the plots by the NRC inspector confirmed that settlements
continue to be uniform, have leveled-off and differential settlements
within the power block are acceptable.
The inspector discussed the above
in telephone conversations on July 2 and 5 with licensee's geotechnical
site engineer. The licensee committed to provide an evaluation of
settlement monitoring up to the present and to provide information on
continued monitoring. Additionally, the inspector requested documentation
to justify:
(1) termination of monitoring between power block markers and
the service water pipeline and, (2) termination of monitoring of safety
related yard lines.
This item is unresolved pending review of the afore-
mentioned licensee information (UNR 85-31-01).

Unresolved Items
Unresolved items are matters about which more information is required in
order to ascertain whether they are acceptable items, violations or
deviations. An Unresolved item is discussed in paragraph 5,
7.
Exit Interview
An exit interview was held June 28, 1985 at the Hope Creek plant with
members of licensee's staff and contractor personnel identified in
paragraph 1.
The inspector summarized the scope and findings of this
inspection.
The licensee acknowledged the inspector's comments.
Additional information resulting from the inspector's evaluation was
communicated to the licensee in telephone conversations of July 2 and 5
as identified in paragraph 5.
No written information was given to the
licensee during the course of the inspection.
