Licensee Action on Previous Enforcement Matters
a.
(Closed) _ Violation 50-424, 425/84-26-01:
" Failure to address all
Essential- Variables in WPS"
Georgia Power Company (GPC) letter of response dated November 14, 1984
has been reviewed and determined to be acceptable by Region II.
The
inspector held discussions with cognizant engineers and examined the
corrective actions as stated in the letter of response. The inspector
concluded that GPC had determined the full extent of the subject
noncompliance, performed the necessary survey and follow-up actions to
correct the present conditions and developed the necessary corrective
actions to preclude recurrence of similar circumstances.
The
corrective actions identified in the letter of response have been
implemented,
b.
(Closed) Violation 50-424, 425/84-36-02:
" Lack of Procedure for UT
Calibration Standards"
'
GPC letter of response dated April 2,1985 has been reviewed and
determined to be acceptable by Region II.
The inspector held
discussions with cognizant engineers and examined the corrective
actions as stated in the letter of response.
The inspector concluded
that GPC had determined the full extent of the subject noncompliance,
performed the necessary survey and follow-up actions. to correct the
present conditions and developed the necessary corrective actions to
preclude recurrence of similar. circumstances.
The corrective actions
identified in the letter of response have been implemented.
The inspector noted that two calibration blocks were identified es
" steel" and two others were identified as " stainless steel" (B-35A-18,
and 19 and B-358-18 and 19).
The licensee was unable to provide any
more definitive information as to type of " steel" or " stainless steel",
but they indicated that they would take the steps necessary to identify
the calibration block material.
The violation is considered closed;
however, the above calibration block material identification question
will be identified as inspector followup item 424, 425/85-23-01:
" Calibration Block Material Identification".
'
c.
(Closed) Violation 50-424, 425/85-02-01:

Adequate Measures to Control Drawing Change Distribution"
GPC letter of response dated March 21, 1985 has been reviewed and
determined to be acceptable by Region II.
The inspector held
discussions ~ with cognizant engineers _and examined the corrective
,
actions as stated in the letter of response.
The inspector concluded
that GPC had determined the full extent of the subject noncompliance,

Independent Inspection Effort (92706B) (Units 1 and 2)
Construction Progress-
The inspector conducted a general inspection of construction block and
adjacent area to observe construction progress and construction activities
such as welding, material handling and control, housekeeping and storage.
j
Within the areas examined, no violations or deviations were identified.

Safety-Related Heating, Ventilation, and Air Conditioning (HVAC) Systems
j
(50100) (Unit 1)
The inspector reviewed the licensee's HVAC program to determine whether the
technical requirements detailed or referenced in the facility Final Safety
Analysis Report (FSAR) associated with safety-related HVAC systems had been
adequately addressed in the construction specifications, drawings, and work
'
procedures.
The applicable codes for the fabrication and installation of
,
i
HVAC systems are:

As-Installed Equipment
The inspector made a walk down of-Control Rcom Air Intake System from
Tornado Damper ' A-1531-W7-304 shown on BPC-AX4DJ2101' to Fire Damper
A-1531-S7-567 shower on BPC-AX4DJ2107 to observe the completed installation
of the following equipment for proper location, configuration, identifica-
tion, and damage.
The basis for this. determination was the FSAR system
description, piping and instrumentation diagrams (P& ids), specification, and
installation drawings.

Gauge PDI-121378 measures pressure drop across the high-efficiency
-
particulate air (HEPA) filter only.
The above is contrary to BPC P&ID
drawing AX4DB-206-3 Rev.10 and FSAR Figure 9.4.1-2 (sheet 3 of 3)
which require gauge PDI-121378 to measure the pressure drop across the HEPA
filter and the downstream cooling coil unit.
-
Gauge PDI-121370 measures pressure drop across the entire 1-1531-N7-002-000
filter unit except for the downstream cooling coil unit. The above is
contrary to BPC P&ID drawing AK4DB-206-3, Rev.10, FSAR Figure 9.4.1-2
(sheet 3 of 3) and FSAR Table 6.4.6-1 which require gauge PDI-121370
to measure pressure drop across the total filter unit including the
cooling coils unit.
-
Several pressure taps, intended to measure differential pressure across
HEPA filters, had the low pressure tap located inside the HEPA filter
rack support assembly, and not down stream of the filter assembly as
shown in BPC P&ID drawing AX408-206-3, Rev. 10 and FSAR Figure 9.4.1-2
(sheet 3 of 3).
Several Pitot Tubes were pointed down stream with the tube opening way
-
from the oncoming air flow.
The above is contrary to the design
function of Pitot tubes.
The inspector discussed the above with the licensee who documented the same in
Deviation Report Control No. PK-2392.
The above are clear examples of failure to perform activities affecting quality
in accordance with drawings, which is in violation of Title Ten Code of Federal
Regulations Part 50, Appendix B, criterion V.
This violation will be identified
as 424/85-23-02: " Failure to Install Pressure Taps in Accordance With the FSAR
and P&ID".
Within the areas examined, no violations .or deviations were identified
except as noted above.

Licensee Identified Items (92700B) (Units 1 and 2)
a.
(Closed) Item 424,425 CDR 84-55: "HVAC Duct Support Weld Discrepancies"
This item was reported to Region II by the licensee in a letter dated
March 2, 1984.
It involves weld discrepancies detected in HVAC duct
supports.
The licensee has utilized MIL STD 105D sampling in their
evaluation. The resident inspector questioned the applicability of MIL
STD 105D to the items and conditions being evaluated.
From a list of 3635 installed and inspected HVAC duct supports, BPC the
Vogtle architect-engineer, randomly selected a statistical sample of 60
supports to satisfy a 95/95. confidence level of support integrity.
This sample was used in a comprehensive visual reinspection program,
using the acceptance criteria of Appendix VC to the HVAC specification
(X4AJ01), to identify clearly and accurately all weld indications on
ecch discrete weld of each support in the sample.

The GPC Construction Department submitted the results of the
-
reinspection program to BPC on June 21, 1984.
BPC conducted an
independent determination of the equivalent available as-built weld for
each reinspected weld with indications, and a verification that
adequate. design margin exists between the required weld strength by
design and the available as-built strength.
This inspector examined the statistically unbiased sample, reviewed the
calculations performed by BPC, and had discussions with licensee and
BPC representatives.
Based on this inspection, it appears that the
sampling and reinspection adequately represent the HVAC support
population, and that the calculations support the GPC contention that
the supports are adequate for their intended service. The question of
reportability under 10 CFR 50.55(e) is discussed in NRC Report 424,
425/85-22.

IE Bulletin (IEB) (927038) (Units 1 and 2)
a.
(0 pen) IEB No. 80-08:
" Examination of Containment Liner Penetration
Welds", Units 1 and 2
The inspector has reviewed GPC's letter of. June 26, 1980, and deter-
mined that the requested actions of the Bulletin have been acceptably
addressed.
The inspector held discussions with responsible engineers,
reviewed supporting documentation and observed representative samples
of work to verify that the actions identified in the letter of response
have been completed.
The inspector selected a sample of penetrations
for radiographic film review.
The sample is indicated below.
The
inspector reviewed the radiographis of the joints welded by Pullman
Power Products (PPP) and Chicago Bridge and Iron (CB&I); however, the
vendor welded intermediate sleve butt weld radiographs were not
available at the time of this inspection.
This matter remains open
pending NRC review of the above indicated radiographs.
