3. 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".

-

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.

7. 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.

8. 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.
