Radwaste Building Shear Wall Design l
l S&W review of seismic calculations of the Millstone 3 auxiliary building i
had identified a problem in the analyses for transfer of horizontal loads to the base mat.
Problem Report PR-S-20 nad been issued and identified this problem as applicable to the Shoreham project.
Further review by S&W determined that only the Radwaste Building might be affectea and that the horizontal load carrying capability of this building should be re-analyzed.
The inspector discussed this problem with the licensee and examined IOM dated March 25, 1981 from S&W to LILCO which states that the reanalyses had been completed and establishes the structural adequacy for horizontal loads The inspector had no further questions concerning this item.

This item was reviewed during inspection 322/80-19 but remained unresolved pending a spot check of additional inspection reports.
The inspector examined additional inspection reports of installation of conduit, pipe and instruments.
These reports showed inspection of anchor bolts in accordance with the revised QC Instructions FSI-F10.4-01, F12.2-04 and F12.1-08 for anchor bolts, raceway and instrument supports.
The. inspector had no further questions concerning this item.

Tube Turn Fittings (79-88-01)
On April 4, 1079, Tube Turns Division of Chemetron Corporation had
-
reported in accordance with 10 CFR 21 that certain 4-inch fittings had been manufactured of material having a carbon content higher than the allowable range.
This item was reviewed during inspection 322/80-19 but remained unresolved since there was no evidence available to confirm the disposal of three of the elbows. This information was also furnished to licensees in IE Circular 79-10.
The inspector discussed efforts to trace the three elbows with licensee representstives and reviewed the documentation shown below.
Since the three Gbows could not be located, Courter examined piping isometrics and change notices to identify and list all ASME 4-inch 45 and 90 elbs FQC verified the Traceability Control Nos.
.
(TCNs) of the installed elbows and determined that TCN-8093 were not installed onsite.
TCN-8093 had been assigned to Lot 6709 elbows.
The inspector confirmed this information by review of the following.

ITT North Power Supplies for Bailey Controls (80-00-02)
By letter dated July 24, 1980, the licensee reported, as a significant deficiency in accordance with 10 CFR 50.55(e), potential failure of power supplies used in Bailey Controls for HVAC equipment. The power supplies had been furnished by ITT North Electric and failure resulted from contamination of the AC stability capacitor which caused swelling and leakage or rupturing of the case.
The capacitors were replaced and tested under the direction of a Bailey representative. The inspector discussed the tests and qualifica-tion of the power supplies with the licensee and reviewed the records shown below.
E&DCR P-3180A which requires tests of the power supplies in
.
accordance with a customer Bulletin issued by Bailey Controls with repair or replacement of any which do not meet the test and certification by Bailey of suitability for use of any repaired or replaced units.
N&D No. 3274 showing replacement of all capacitors after failure
.
of three under test.
Tests of the replaced capacitors were acceptable.

Square D Motor Control Center Starters (80-00-03)
By letter dated November 20, 1980, the licensee reported, as a significant deficiency in accordance with 10 CFR 50.55(e), a defect in the Nema Size 3 contactors of Square D 480V Motor Control Centers (MCCs). The defect was caused by application of a lubricant to rubber bumpers which are attached to the movable starter armature and which caused the bumpers to stick to the starter case.
In some cases the coritactors would not close when required. This item was also reported by S&W in accordance with 10 CFR 21 (81-88-01).
The inspector reviewed documentation onsite which identified 9 starters onsite containing a total of 15 contactors which had been manufactured within the time frame identified by Square D and showing that corrective action had been completed.

Weld Defects in Square Tubing (81-00-02)
,
The licensee reported on February 27, 1981, in accordance with 10 CFR 50.55(e) a potential deficiency in welding of square tubing. On March 9,1981, the licensee reported that further investigation of a sample of tubing had identified no additional unsatisfactory welds and therefore the prob 1cm was not a reportable deficiency in accordance with 10 CFR 50.55(e).
The inspector reviewed the following records:
N&D No. 3880 datad February 27, 1981 which showed that lack of
.
fussion had been identified in seam welds of 3" x 3" and 4" x 4" steel tubing. A total of 45,000 lineal feet of tubing had been purchased. A sample (MIL-STD-1050) of 500 lineal feet was examined and showed no additional weld defects.
The N&D was closed based on results of sample inspection.
10C to FQC instructed FQC to inspect 500 feet of 3-inch and
.
4-inch tube steel; 200 feet in reactor building; 150 feet in Minifab Shop and 150 feet in storage areas.
FQC Inspection Report dated March 2, 1981 showed 549 feet of
.
3-inch and 4-inch pipe inspected and found to be satisfactory.
The inspector had no further questions concerning this item.
f.
Bergen-Paterson Snubber Deficiencies (80-88-02)
By letter dated June 20, 1980, Bergen-Paterson Corporation (B-P)
reported, in accordance with 10 CFR 21, certain deficiencies in a limited number of strut assemblies with mechanical shock arrestors (snubbers) furnished by Pacific Scientific Company (80-88-02).
These potential problems were also identified in IE Circular 79-25.
An additional problem concerning the load capacity of assemblies using Part 2540-120 was later identified by B-P and was identified to licensees in IE Circular 79-25, Supplement A.
This item was reviewed during NRC Inspection 80-05 and 80-19 but remained unresolved.
The inspector again reviewed the status of inspection and rework of the hangers identified by Bergen-Paterson as potentially deficient. The records show 13 units not received onsite; 7 units received but not inspected; 4 units rejected and returned for corrections; and 5 units to be orovided with new brackets to upgrade their capacity.
This item remains unresolved pending completion of corrective action.

Licensee Action on Previous Inspection Findings (Closed) Noncompliance (80-10-02):
Failure to meet separation requirements of specifications for conduit installation.
N&D No. 3398 was written to document this nonconformance and to require documentation prior to sign-off by construction.
The disposition requires that such exceptions be documented on an E&DCR and identifies E&DCR F29154 as documenting nonconforming conditions in question.
The inspector confirmed this action by examinat!ons of E&DCR F29154 and QC Instruction QC1-FSI-F12.1-08G, " Inspection of Raceway / Conduit Installations." Paragraph 5.3.6 of this QC1 establishes the same requirements.
(Closed) Unresolved Item (80-10-0):
Clarification of painting inspection reports.
The inspector examined the following documents:
N&D Report No. 2882 which nad been dispositoned, reworked and closed
.
on January 5, 1981.
The disposition required inspection and test of the entire surface a.1d rework of the defective areas.
FQC inspection report dated January 2,1981 confirmed that the rework was in accordance with the disposition and was acceptable.
E&DCR F29203 and F29203A concerning surface preparation and coating
.
of areas behind clip attachments.
KTA-Tator Associates Daily Painting Inspection Reports No. 732, 735,
.
736, 737, 738 and 739 of surface preparation and coating of down comers and areas behing clip attachments.
The inspector had no further questions concerning this item.
(0 pen) Unresolved Item (00-19-01):
Review for reportability in accordance with 10 CFR 50.55(e) of deficiency in Velan Swing check valves.
The inspector was informed that this problem had been reviewed by S&W and was not considered reportable. However, there was no documentation onsite to substantiate this review.
The inspector requested that such documentation be provided and also that the licensee independently review this problem for reportability.
In addition, the inspector requested that the licensee examine their procedures to determine whether items which are not identifed on N&D reports might escape review for reportability.

at the conclusion of the inspection on March 26, 1981.
In addition, the NRC Senior Resident Inspector, Mr. J. C. Higgins attended the meeting.
