Functional or Program Areas Inspected 1.
Review of Pipe Support and Restraint Specifications The inspector reviewed the following specifications:
The Detroit Edison Company (DECO)
Spec. 3071-42
" Hanger Material," issued December 17, 1970.
Spec. 3071-528 " Design Specification for Mechanical Seis=ic Shock Suppressors," issued February 20, 1976.
Spec. 3071-151 " Pipe Whip Restraints," issued April 16, 1973.
Spec. 3071-31
" Pipe Erection," Revision A, issued April 30, 1975.
-2-
-
.
,
General Electric Company (CE)
Spec. 21A9345
" Pipe Suspension," Revision 1, issued September 16, 1970.
In regard to DECO Spec. 3071-528, the inspector commented that the mechanical snubber lockup acceleration or velocity and load relief characteristics had not been specified. The licensee stated that there will be a contract document change to address these items, and the revisf an will be reflected in the Bill of Materials. This is an unresolved item.
(341/78-14-01)
Within the areas reviewed, no items of noncompliance or deviations were identified.
2.
Review Piping Suspension Installation Procedures The following Wismer and Becker Contracting Engineers (W&B)
'
procedures were reviewed by the inspector:
'
WB-C-ll4, " Field Fabrication and Erection of Pipe Supports",
.
Rev. 4, dated April 26, 1978.
WB-C-105, " Concrete Anchor Installation and Testing", Rev. 4,
.
dated April 5, 1978.
Welding Process Specification, WPS-7002, " Welding Procedure
.
for Structural Attachments", Rev. 6, dated August 26, 1978.
Other W&B procedures scheduled for issue in the later part of 1979 will be reviewed during future inspections.
Within the areas reviewed, no items of noncompliance or deviations were identified.
3.
Followup on Previously Identified Hanger Inspection Findings During the inspection on March 28-29, 1978, Rev. 1 of Procedure WB-C-114, " Field Fabrication and Erection of Pipe Hangers and Restraints" was reviewed by the inspector, and the deficiencies identified were documented as an infraction in RIII Report No.
50-341/78-03. During this visit, the inspector reviewed the following:
a.
W&B inspection plans for the approximately 375 (previously reported 50) safety related hangers installed by the Ralph M. Parsons Company. To the date of inspection,152 had been completed.

.
b.
Rev. 4 of Procedure WB-C-ll4, relative to the timely QC inspection requirements, was considered adequate.
c.
Detailed inspection checklists including qualitative and quantitative acceptance criteria have been included in Rev. 4 of procedure WB-C-ll4.
This item is considered closed.
4.
Review of Measures to Correct Identified Hanger Installation Deficiencies During May 1 to August 28, 1978, the W&B QC inspected 152 Parsons installed, and 104 W&B installed safety related (QA Level I)
hangers, and rejected all of them. The problem as documented involved:
(1) rejectable weldments, (2) deviation from design requirements, (3) damage of materials (4) fasteners not properly tighten, (5) lack of permanent hanger identifications, and (6) clearance not in accordance with requirements. The inspector concluded that there is a lack of corrective actions for these identified hanger deficiencies based on the folinwing findings:
a.
Neither the 152 rejected safety related hangers installed by the former contractor, nor dhe 104 rejected safety related hangers installed by the present contractor had been repaired to the date of this RIII inspection. (Twenty nine Parsons and 37 W&B hangers were rejected in June,1978; 120 Parsons and 35 W&B hangers were rejected in July,1978; and 3 Parsons and 32 W&B hangers were rejected in August, 1978 by the W&B QC inspectors). The inspector observed that there was no apparent plan to correct problems on hand and prevent future recurrence and installation activities had not been curtailed.
b.
There appeared to be a lack of procedural requirements specifying a limitation on the time for corrective measures to be initiated.
c.
The present system of reporting QC hanger inspection findings to the construction group had seemingly bypassed the site nonconformance control and resulted in QA not being able to perform an effective trend analysis, d.
Although the licensee plans to audit the hanger installation and inspection program, no schedule for audits was available.
A draf t audit plan had been prepared.

This is considered an item of noncompliance with 10 CFR 50,
~
Appendix B, Criterion XVI, and Enrico Fermi 2 FSAR, Section A 17.5.16.
(341/78-03-02)
Prior to the conclusion of the inspection, on September 8,1978, the following corrective action had been initiated by the licensee:
a.
The W&B Project Quality Manager issued Halt Work Directive No. 7 stopping all work on installation of QA Level I hangers.
b.
Plans were established for DI engineers to verify all safety
-
related hanger installations prior to release for QC inspection.
c.
A trend analysis on installed W&B safety related hanger deficiencies had been carried out by the licensee QA department.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance, or deviations. An unresolved item disclosed during the inspection is discussed in Paragraph 1.
Exit Interview The inspector met with site staff representatives (denoted under Persons Contacted) at dhe conclusion of the inspection on September 8,1978.
The inspector summarized the purpose and findings of the inspection.
The licensee acknowledged the findings reported herein.
