2.
Licensee Action on Previous Inspection Findings (0 pen)UnresolvedItem(79-21-01): Support of Control Rod Drive (CRD) insert /
withdrawal lines. The inspector was informed that re-analysis of the supports had been completed and rework was in progress. The inspector observed that additional supports had been installed for the previously observed lines which now appeared to be adequately supported.
This item remains unresolved pending completion of rework and final inspec-tion of the CRD system.
3.
Review of Non-Routine Events Reported (0 pen)10CFR50.55(e) Deficiency (81-00-01): Deficiency in lubrication of turbocharger thrust bearing for Diesel Generator. The inspector reviewed E8DCR's F-36401 and F-34540 including revisions A through F, and was informed by the licensee that the required changes had not been completed.
This item remains unresolved pending completion of the work, inspection by FQC, and review by an NRC inspector.

(0 pen)10CFR50.55(e) Deficiency (81-00-08): Failure of high-density fire stops to be retained in floor penetration sleeves. The inspector discussed the design of supports for these fire stops with the licensee and questioned the effect of a fire on these supports. The inspector also examined BISCO (Brand Industrial Services, Inc.) Test Report No. 748-18, which provided the results of a three-hour fire barrier test conducted at the Construction Tech-nology Laboratories of the Portland Cement Association. The supports were not included in the tests. The licensee expressed the opinion that supports would not be required in case of fire since expansion of the fire stop would be sufficient to retain it within the sleeve.
This item remains unresolved pending engineering justification for accepta-bility of the proposed design.
(0 pen) 10 CFR 50.55(e) Deficiency (81-00-09): Effect of hydrodynamic loads on CRD systems. The inspector was informed by the licensee that a series of tests had been performed starting at various rod positions. The results of these tests are still under evaluation.
This item remains unresolved pending completion of evaluation of test results by the licensee and rework of the system if required.
(Closed) 10 CFR 50.55(e) Deficiency (81-00-10): Defect in spherical washer subassembly for emergency diesel generators. This item had also been re-ported by the manufacturer, Transamerica DeLaval, in accordance with 10 CFR 21. The inspector was informed that the spherical washers had been replaced by belville washers and that the piston assemblies had been returned to the manufacturers plant for this rework. The inspector examined the following documents:
--
Repair / Rework Requests R-43-215, R-43-216, and R-43-217 for removal and replacement of pistons.
--
LILCO QA Inspection Reports for installation of pistons and connecting rods of DG's No. IR43*DG-101, 102, and 103.
--
Vendors certificates of conformance.
--
Stone & Webster Quality Assurance Certifications.
E&DCR No. F-3F313, which provides manufacturers instructions for pis-
--
ton modifications.
(Closed) 10 CFR 50.55(e) Deficiency (81-00-11): Electrical bus supports and bracing for GE 4160 volt switchgear may not withstand momentary short circuit loading. The inspector discussed this question with the licensee's engineers and reviewed the following documents:

.
.
GE letter dated November 9, 1981, which identifies the problem and
--
states that additional bracing is required for momentary current in excess of 66,000 amperes.
S&W 1etter, LIL-19225 dated January 18, 1982, which states that sup-
--
ports for two of the switchgear buses (IR22-SWG1A&B) should be reworked.
The remaining switchgear require no modification.
The licensee stated tha SWGIA&B are category II equipment and, therefore, this item is not reportable under 10 CFR 50.55(e). However, the supports for these items will be modified.
(Closed)10CFR50.55(e) Deficiency (82-00-02): Cracks in fusion welded square steel tubing. This item had been reported as a potential deficiency when cracks were found in two of five 20-ft. sections from the same heat of A-500 tubing.
This item was determined to be not reportable since no additional cracks wer6 found by inspection of all accessible tubing from the same heat of material and a failure analysis by S&W postulated that the crack was present in the plate used for fabrication of the tubing and propogated during fabrication.
(Closed)10CFR21 Deficiency (81-88-03):
Potential interference on cer-tain Bergen-Paterson strut assemblies with mechanical shock arrestors.
This item had been reviewed during inspections 50-322/81-08 and 50-322/82-01.
The inspector discussed this problem with the licensee and FQC representa-tives and reviewed records of inspection of these assemblies. The identi-fied supports had been inspected and either found to be acceptable or modi-fied except for three assemblies which had not been received for inspection by FQC. These assemblies have been identified for inspection by FQC in ac-cordance with ESDCR F-34786.
(Closed) 10 CFR 21 Deficiency (81-88-05): Defect in spherical Wather sub-assembly for emergency DG. Thisitemwasalsoreportedunder10CFR50.55(e)
(ItemNo. 81-00-10) and was closed as discussed above.

Licensee Action in Response to Bulletins and CircularsBulletin 79-14 (Closed): Seismic Analysis of Safety Related As-Built Piping.
The inspector discussed this item with licensee and with S&W Field QC (FQC)
and Site Engineering Office (SEO) personnel and reviewed a sampling of SEO and FQC records and the following procedures:
Project Procedure No. 42, Rev. 1, " Seismic Category I As-Built Piping
--
Review and Reconciliations."
Construction Site Instruction CSI-9.14, " Stone & Webster Task-Large
--
Bore As building Procedure."

.
CSI-9.15, " Stone & Webster Task - Small Bore As-Building Procedure."
--
Quality Control Instruction QCI No. FSI-F11.5-001, "As-Built Piping
--
Systems Inspection."
These procedures provide a system for reconciliation of seismic Category I as-built piping systems with their as-analyzed conditions and for inspection by FQC for verification of the as-built conditions.
In sumary, the system provides for the following steps after completion of installation by the pip-ing contractor:
4.
The "As-Built Group" performs a line walk (including measurements) to verify the as-built condition of the system.
b.
SE0 reviews as-built isometrics against stress sumaries of the system.
c.
After review of SEO, a copy of the isometric is sent to FQC for inspec-tion.
SE0 review may result in acceptance, requirement for field changes or submit-tal to S&W Boston for further review or re-analysis. Any requirement for field changes by either SEO, Boston, or FQC will result in repetition of the entire process.
5.
Exit Interview The inspector met with licensee and contractor personnel (denoted in Details 1) at the conclusion of the inspection on May 21, 1982. The inspector sum-marized the scope and findings of the inspection.
