l.d(3), and 1.d(7). Noncompliance 77-10-06 identified deficient installation records, (Form 19 - Weld Inspection Checklist), for switchgear buses No. 65E and 72 Also, as identified in IE Report No. 78-08, L. K. Comstock Field Surveillance Correction Reports, FSCR, No. 272 and 281 indicated an installation drawing which referenced an inaccurate standard for grounding. The corrective action taken with regard to noncompliance No. 77-10-06 subsection 1.d(2), 1.d(3), and 1.d(7) has been verified and closed in IE Report No. 78-10. During this inspection, the inspector reviewed additional installation records, Form 19, which had been completed indicating reinspection of the plug welds. Training relevant to Form 19 has been documented as being ecepleted on the Training Attendance Log dated July 24, 1978. New FSCRs (No. 600-606 and 608-612) have replaced FSCR No. 272 and 231 to identify the proper drawings and grounding standard. Design Change Notice No. 1001 har-2-

However, the RIII inspector expressed concern about using a lower pressure than the original test pressure of 63 psi. The inspector reviewed nonconformance DDR(E)2023 which supersedes DDR(E)1707 to determine if the revised d1sposition was adequate. The Detroit Edison Field Engineering disposition for DDR(E)2023 states in part: "a pneumatic test using Conax leak test procedure (IPS-84.1 paragraph 4.1.7) will be performed on penetration 104E. If the penetration meets this test criteria the penetration will be acceptable."

show cause letter dated May 24, 1978. DIC issued an extension of the interface program plan and evaluation period on September 1, 197 This extension was granted due to the recent arrival of the new L. K. Comstock QC Manager. The extension letter states in part:

"the Interface Program Plan and evaluation period shall be extended until October 1, 1978. If during this evaluation period it is determined that the nev QC manager has established the necessary discipline and control over the QA Program and corrective action status is adequate, the number of Daniel QA/QC personnel directly involved can be reduced." The RIII inspector reviewed a summary of L. K. Comstock's action plan progress and determined that answers to thirty-four out of thirty-seven Daniel Audit Finding Reports (AFR) have been submitted to Daniel's QA department for close-out; eighteen have been closed by Danic 's QA. L. K. Cemstock has made twelve revisions to their QA Manual to correct deficiencies that were identified in Daniel's QA audits. The inspector reviewed Daniel's QC evaluation reports on L. K. Comstock's training-3-

program; the reports indicate the program is adequate. Additionally, the RIII inspector interviewed DECO's site QA Manager and Daniel's Project QA Manager relative to their assessment of LKC's progress during the past two months. The consensus is that L. K. Constock has turned their program around and that with the addition of a new QC Manager full implementation of their program should be evidenced by October 1, 197 .

i 1. Observation of Recent Electrical Work Activities a. The RIII inspector observed and discussed with the pertinent QA and craf t personnel the following installed raceway sections for the Control Rod Drive System:

. Wirevay #41-014 per Deco drawing #61721-2866-2 Rev. A

. Wireway d41-006 per DECO drawings #6I721-2866-8 Rev. B and 6E721-2801-9 Rev. B (

. Wirevays #11-006,11-007,11-010 and 11-011 per DECO drawings #6I721-2866-8 Rev. E and #6E721-2801-9 Rev..B The QC and craft personnel were knowledgeable of the installation requirements. The wirevays were tack welded, grounded, and identified in accordance Sargent & Lundy Standard #EB-117.57, Design Change Request #E-0865 Rev. B, and Design Change Notice #393 dated December 15, 1977, respectively. The routing, separation (except as noted),

segregation, absence of sharp edges, hanger spacing, and cleanliness were in accordance with the drawings and L. K. Comstock Work Instruction #000-03-021 dated February 10, 1978. Wireway #11-006, as installed, violated the cable tray separation criteria. The violation was properly documented

,

and controlled on Deviation Disposition Request #295 dated August 14, 197 The RIII inspector observed the following two installed Class IE panels:

dated January 14, 1972, did not specify the type of lugs to be used. The inspector inquired as to whether the spade lugs used in these panels meet the seismic criteria of the Fermi 2 site. The documentation supplied with these panels included only Product Quality Certifications from General Electric which did not indicate whether the

,

spade lugs were seismically qualified or not. The licensee stated that there is a scheduled audit of General Electric by Detroit Edison within the next two months, which would verify the validity of the Product Quality Certifications. The licensee stated that the seismic qualification of the spade lugs would be pursued during that audit. This matter is unresolved. (341/78-13-01) The RIII inspector observed the following four installed Class IE cables in Control Rod Drive wireway: #251102-22, 232015-22, 2000289-2C and 200598A-2C.

I The cables were properly routed in accordance with the pull cards. The raceway was free of sharp edges and grounded. The separation criteria, identification, bend radius, and sealed cable ends were in accordance with L. K. Comstock Work Instruction #000-03-008 dated July 21, 1978 and related document The RIII inspector observed the following completed cable terminations:

Cable #200028B-2C from end Cable #200598A-2C from and (partial)

Cable #200597C-2C to and from ends Cable #2000213-2C to and from ends The following termination chsracteristics were in accordance with the pull cards, L. K. Comstock Work Instruction #000-03-019 dated August 15, 1978, and Detroit Edison Specification

  1. 3071-128 Standard #EA-3-1:

Cable supports, color / numeric code, crimped lugs, conductors identified, separation criteria maintained, properly dressed conductors, and tight connection No itecs of noncompliance were identifie . Record Review of Recent Electrical Work Activities The RIII inspector reviewed the following records concerning the aformentioned observed installations: Cable Tray Installation Inspection Check List (L. K. Comstock Form 17) for wireways #41-014,41-006, and 11-00 _ ._

observed, were knowledgeable of the installation requirement During inspection of the 4160V switchgear room, the inspector expressed concern relative to the installation of rigid conduit mounted to seismic Class I equipment. Prior to the completion of the inspection, the licensee's engineering department issued Design Change Notice 1199 to specification 3071-128, STD-ED which states in part: "1il existing conduit terminating at Class I equipment that does not conform with item 8.8.1 of the specification (as of August 30, 1978)

will be analyzed for acceptability." This matter is unresolve (341/78-13-02)

7 Two limitorque valve operations (motors), that were stored in the auxiliary and reactor buildings, were inspected to determine if the stem nuts were secured by locking nuts and that the top thread of lock nuts were crimped or staked in 2 places in accordance with Limitorque Instruction and Maintenance Manual, SMBI-170. The aforementioned' valve operators were staked, as required. However, the inspector expressed concern to the licensee, relative to all QA Level I Limitorque operators which are installed and/or being installed that existing receipt inspection and/or installation procedures do not require a similar inspection. The licensee indicated that, in their view, this inspection was the responsibility of the vendo Prior to the completion of the inspection, twenty limitorque valve operators were inspected at random by Daniel QC personnel and two operators were found that did not have their lock nut staked, as required. As a result, Daniel International Corporation and Wismar-Becker QC personnel issued nonconfornance report DDR(M)2043 which requires in part that this inspection i

be included as a specific check item for each Limitorque

'

operator, that inspection records be available for QC audit, and thzs the vendor be contacted abcut this problem. This matter is unresolved. (341/78-13-03)

Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, item of noncompliance, or deviations. Unlesolved items disclosed during the inspection are discussed in Section I, paragraph 1.b. and Section II, paragraphs 2.b. and .
