Tours of Unit 5 were limited to. verification of inert atmosphere for heavy equipment.in the storage area near the Unit 3 cooling tower and a two-hour-toursof the Unit 5 RAB on June 2 No items of' noncompliance were identifie . Project Construction Status - Un'it 3 At the end of the report period, project site construction had reached 56 percent completio The Supply System submitted their application for an operating license to USNRC-NRR (Office of Nuclear Reactor Regulation) on June 2, 1982. On June 28, 1982 the site was visited by the Licensing Project Manager from USNRC-NRR for tours of site and environs and meetings with Supply System personne . Licensee Organization Change On June 16, 1982 the Licensee informed the NRC that the site QA organization would report to the Corporate Quality Assurance Director rather than the WNP-3/5 Program Directo . Licensee Action on 10 CFR 50.55(e) Construction Deficiencies Radiograph Indications on Unit 3 Safety Injection Tanks During the report period, numerous contacts were made with the Licensee, Ebasco and CE personnel on this subject.

-3-Licensee's final 50.55(e) report was examined and the original radiographs were read for the nozzle to safe end wel Also, the overlays for the indicated repairs were examine As a result of this examination, the licensee was requested (by letter from RV) to provide additional information regarding the disposition of the radiograph indications prior to closing the ite Concerns regarding information provided by the vendor were directed to the Vendor Inspection Branch of Region IV. This item will remain open for further follow-u Pipe Hanger Stiff Clamps The resident inspector identified two items which the licensee agreed to address in addition to the thirteen questions of NRR following their review of stiff clamp design on June 18, 198 (1) For clamps which were tightened prior to the identification of the original design concern reported as a 50.55(e)

item, will the straps be treated as overstressed and re-placed?

(2) Is there a contact distance requirement for the fit of any yoke to the pipe? In other words, does a field inspector have a means of identifying inadequate or improper fit of the yoke to any pipe? For ease of con-trol, these questions will be addressed separately from the 50.55(e) and the thirteen NRR question This item will be identified as " Stiff. Clamp Installation Concerns" (50-508/82-13-01) and considered a follow-up ite . Other Construction Deficiencies The following construction deficiency was examined in detail by the resident inspector to an extent of meetings and direct field inspection of the proble It was not addressed as a 50.55(e) ite Reversal of Cold Leg Elbows in Primary Loop The cold leg elbows of the primary loop piping at the exit from the steam generator on CE System-80-NSS systems are provided with a 3/4-inch straight section so that the ASME code provisions are applied tota straight section weld. The contractor installing the iipe.was unaware of this feature of the elbows and thus the' elbows' assumed a random orientation since they were unmarked by the vendor. Disposition of the nonconformance was simply to insure that elbow-to-pipe weld section met the code requirements for- a. curved junction rather J

(1) that the construction planning of the Joint Venture did not include sufficient drawing review to recognize the possi-bility of misorientation of the elbows, and (2) that this has reportedly occurred at other plants but the vendor has not taken precautions to warn their clients or otherwise mark the elbows. No items of noncompliance were identifie . Action on Previously Unresolved Follow-up and Enforcement Items (Closed) Follow-up Item (50-508/509/81-08-30) Ebasco - Procedures and Maintenance of Calibration Records In inspection report 50-508/82-06 item of noncompliance 50-508/81-08/05 was closed. The closure of the item of noncompliance also addressed the concern expressed in this follow-up~ item. The matter is close . Installation of Instrumentation for Control Room During the month observations of control room panel installation were mad The NRC inspector found that the control room environ-ment was being degraded by a shop area and the leakage of rain water through the uncompleted south walls of the adjoining south relay roo These concerns were immediately addressed by the contractor (F & M).

The inspector also observed that fibre optics cables were not identified so that craftsmen could exercise appropriate car Ebasco initiated appropriate correction No items of noncompliance were identifie . Primary Loop and Other Safety Related Pipe Welding During the month the inspector examined records for primary loop weld No. 3 FW 11 The inspector questioned the absence of Condition Evaluation Reports (CER's) in the assembly of the data packages since such reports were necessary to complete the information supplied by the Inspection Reports (IR's). The contractor will address this concern and, prior to final assembly of the data pack-ages, will assure that pertinent CER's are included in the data package The records for weld rod issued for this weld were exam-ined to specifically determine that ER 309 and ER 308 were issued in the proper sequence. Primary Loop Weld 3 FW 113 was also included in this examinatio _

Field observations of actual welding were continued for all primary loop weld Delta ferrite measurements were made on all field welds in the stainless steel piping for both core spray lines in the annulus between 400-foot level and the 374-foot level. Ferrite numbers between 5 and 12 were found for the field weld (Ferrite numbers of shop welds were generally lower.) Although no specific require-ment exists for the measurement of delta ferrite in completed welds, the data does provide an indication that delta ferrite is being adequately controlled by the Joint Ventur No items of noncompliance were foun . Surveillance of Safety Related Welding by Ebasco A sample of surveillance reports by Ebasco on this activity were examined. Report No. 224-229 was questioned since it reflected a repetition of previous concerns regarding welder qualificatio The response to the Quality Finding Report did not appear'to directly address one concern of this surveillance report dealing with the possible use of welders unqualified for open root weld The possibility of ineffective corrective action was reflected in the reports and in the repetition of the surveillance engineer's concer Further follow-up will be performed to assure resolution of this concern. Follow-up item 50-508/82-13-02, "Ebasco Surveil-lance of Welding".

1 Reinforced Concrete Block Walls Rough calculations of walls 41 and 42 in the North Diesel Generator room raised questions regarding the seismic design margin. The resident inspector has referred his concern to Region V for review and the question is also being addressed by the licensee. Follow-up item number will be 50-508/82-13-03 titled " Block Wall Design Adequacy".

1 Exit Interview On July 1, 1982, the NRC inspector met with the WNP-3/5 Project Manager and other Supply System personnel. The highlights of this report were discussed. Weekly meetings were also conducted with the Supply System QA Manager as necessary to properly apprise the licensee of NRC inspection activity.
