10 CFR Part 50, Section 50.55(e) Reportable Deficiencies The inspector reviewed activities that have teken place regarding the
,
following reported deficiencies:
'
Gould, Inc. Defective Nema 3 Starters A work request (WR 00228) signed on November 26, 1979 was issued to check all motor control centers for defective contactors.
This work I
was completed on November 28, 1979 with a total of 22 size three
,
Gould starters of six different motor control centers checked for
'
date stamp numbers identified by Gould as being among the defective type and for carrier clearance (.015").
Only one contactor carrier l
was found that had a clearance problem.
(Breaker AB 1A-4E, standby liquid control pump 1A).
It was established that this carrier assembly was replaced with a new carrier supplied by Gould Inc.
The inspector concluded that this reported deficicency has been i
adequately corrected.
I&E Bulletin 79-02 I&E Bulletin 79-02 response was discussed with the licensee during i
this inspection. The RIII concerns are addressed in paragraph 2 of the Functional or Program Areas Inspected section of this report.
Functional or Program Areas Inspected 1.
Review of Containment Structural Integrity (SIT) Procedure The inspector performed a review of the Zimmer plant Containment Structural Integrity Test procedure to verify that the procedure includes the requirements of Regulatory Guide 1.18, ASME Section
III, Division 2, Article CC-6000, 1977 Edition and the licensee i
FSAR commitments.
l This item was previously reviewed in Report No. 358/78-03-02 dated January 30-31, 1979 and was considered an unresolved matter. This followup was to verify the corrective action taken to the subject
'
unresolved matter.
It was determined that the procedure PRP-05 had been fully approved by engineering and quality assurance as of April 5, 1979. The procedure did not incorporate the applicable design requirements set forth in the CG&E FSAR and ASME Section
,
III, Division 2 code.
This matter is considered an item of noncompliance with 10 CFR 50, Appendix B, Criterion XI (Test Control) as described in detail in the Notice of Violation attached to the letter of this report (358/80-03-01).

Evaluation of Licensee Response to IE Bulletin 79-02 An evaluation and inspection was performed of the licensee's response to IE Bulletin 79-02, pipe support base plates using concrete expan-sion anchor bolts. Previous inspection of this item is documented in NRC inspection reports 358/78-18, 358/7822 and 358/79-03 performed prior to issuance of the subject bulletin.
Item 1 regarding the developing of anchor bolt loads including a.
base plate flexibility has been reviewed by the NRC staff (NRR).
Their review indicates that the bolt stiffness used in the flexibility analysis is not acceptable in that the stiffness used is too low.
In addition the staff intended the flexibility analysis to use the maximum design load rather than four times that load as indicated in Section 3.3.1 of the July 6, 1979 submittal. This item is considered unresolved (358/80-03-02).
b.
Item 2 required the licensee to verify that a minimum factor of safety of four for wedge type anchors and five for shell type anchors exist between bolt design load versus bolt ultimate loads. The licensee's response is considered unacceptable in that a minimum factor of safety of two was used for emergency and faulted conditions. This item was brought to the attention of the licensee and is considered unresolved pending submittal of a revised response (358/80-03-03).
Item 3 required the design requirements for anchor bolts to c.
withstand cyclic loads. The licensee's response indicated that the base plate design used Operating Basis Earthquake event. The bulletin intended the licensee to use Safe Shutdown Earthquake (SSE) event. The licensee's response is considered unacceptable pending submittal of a revised response to include the effects of SSE loading. The item is considered unresolved (358/80-03-04).
d.
Item 4 required the licensee to perform a field verification of base plate installations using concrete expansion anchors. The licensee did establish a field inspection program to verify in-sta11ation of the expansion anchors. The program has identi-fied a significant number of nonconformances and deficiencies.
The S&L procedure DDC-328 Section 2.2.2 requires "one bolt per hanger shall be inspected for torque and minimum embedment.
If this selected bolt is unacceptable, all bolts of the hanger shall be inspected." This inspector questioned the validity of the one bolt per hanger sample in view of the significant number of nonconformances identified on the first bolt inspection.
The inspector requested the licensee to develop a summary identi-fying the nonconformance number, the hanger support effected, a description of the nonconformance, and the status of the noncon-formance in order to evaluate whether a 100% inspection is re-quired. This item is considered unresolved pending the above review (358/80-03-05).

e.
Item 5 required the licensee to determine the extent that con-crete expansion anchors were used to attach piping systems to masonry block walls.
In addition, this item required a list of systems, the number of supports, line size and accessability of supports attached to block walls.
The licensee's response indicates the use of block walls to support piping systems; however, is incomplete in that the information requested was not included in the response.
The inspector determined by S&L letter (SLC-11991) dated January 9, 1979 that the Zimmer plant has 311 masonry block walls that are used to support pipe supports.
This item is considered unresolved pending submittal of the required information requested by Item 5 of the subject bulletin (358/80-03-06).
The subject of concrete expansion anchors used in block walls to support cyclic loads is under review by the NRC staff.
Unresolved Items Unresolved matters are items about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance or deviations. Unresolved matters disclosed during this inspection are discussed in paragraph 2 of the Functional or Program Areas Inspected section of this report.
Exit Interview The inspectors met with site staff representatives (denoted in the Persons Contacted paragraph) at the conclusion of the inspection on January 24, 1980. The inspectors summarized the scope and findings of the inspection and emphasized the concern regarding the inadequate Containment Integrity Test procedure that had been reviewed and approved by licensee personnel.
