Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (IE Reports No. 456/78-03-02; 457/78-03-02):
CECO Electrical Construction Test Procedure manual not clearly assuring compliante with ANSI N45.2.6 (for test personnel) and measures assuring that power cables are insulation resistance tested prior to their final termination. No installations nor testing of Class IE cables has occurred at Braidwood site; also no Class IE work is expected to be conducted in the near future (construction / installation activities of Class IE equipment has stopped). This item is closed, further evaluation of electrical in-stallations will be performed once construction at the Braidwood site has resumed.
(Open) Item of Noncompliance (IE Reports No. 456/79-12-01; 457/79-12-01):
Failure to have plans and procedures to control safety related activities during an extended construction delay. The inspector observed that CECO has written a special QA plan for the Braidwood Station during the extended construction delay. Also, several maintenance procedures have been written and are in the process of being approved. This item remains open pending NRC's receipt and evaluation of CECO's response to the item of noncompliance identified in IE Reports No. 456/79-12 and 457/79-12.
Functional or Program Areas Inspected 1.
Status of the Site Staff - Units 1 and 2 The CECO Project Superintendent informed the inspector that current site staff consists of approximately 140; this includes craft and supportive personnel. The Superintendent further indicated that this number may drop to 110; 50 of these would be craft personnel.
The inspector toured the various site work spaces and observed that most of the craftsmen were working on clean-up and maintenance assignments; most of the supportive personnel were working on assem-1756 005-2-

bly of quality records.
inspector observed that CECO currently
has only two Quality Assua
- e/ inspection personnel assigned at the site. The inspector waa informed, by these personnel, that as the need arises (for additional QA/ inspection personnel) the Braidwood project will request aid from the Byron project, the La Salle pro-ject or from the CECO downtown offices.
No items of noncompliance were identified.
2.
CECO Site QA Audit of Station Construction - Units 1 and 2 The inspector reviewed CECO site QA Audit repor? QA-20-79-48 and observed:
.
a.
CECO site QA personnel conducted an audit of the site main-tenance activities during the last week of October, 1979.
b.
The audit covered such points as; documentation, inspection and frequencies of the maintenance.
c.
The audit revealed at least thirteen instances where the pre-scribed frequencies for maintenance of safety-related equipment was not being adhered to.
d.
The audit report has not yet been responded to by Station Construction.
The inspector discussed the audit report with Station Construction personnel and was informed that many of the manufacturers, of sup-plied equipment, has required unrealistic maintenance frequencies for their equipment.
Station Construction personnel indicated that they are currently discussing, with the applicable manufacturers, this issue to try and preclude loss of manufacturers " warranties".
No items of noncompliance were identified.
3.
CECO Vendor Surveillance - Units 1 and 2 Since the shutdown of canstruction activities for the Braidwood project:
a.
Station Construction has been requested on four occasions, by off site vendors, to observe inspection eitness points which were previously selected by CECO. CECA provided inspection personnel to witness vendor work activities for only one of the requested occasions.
b.
The inspector was informed by the licensee that for the other three requested occasions; the work activities to i756 006-3-
,
be witnessed were generic type oberservations not highly
.
critical to the product manufacturing process. The in-spector observed CECO telephone communication records which indicated that the manufacturer in these three instances was Westinghouse, Tampa division. The inspector reviewed a
" draft" list of off site vendors from whom CECO anticipates receipt of safety-related equipment, systems and or components during the extended shutdown period.
Approximately 23 of these vendors will be supplying mechsaical equipments and 22 of them will be supplying Class IE equipments. The licensee stated that many of the listed vendors will require shop in-spections by CECO personnel, as their contracts contain witness points requiring CECO notification for in process ob-servations. During subsequent inspections NRC personnel will evaluate the coverage by CECO personnel of the 55 off site vendors (456/79-14-01; 457/79-14-01).
No items of noncompliance were identified.
4.
Other Areas Inspected - Units 1 and 2 The inspector toured the-laydown areas, warehouses, reactor contain-ment buildings, auxillary building and the turbine building and ob-served:
Most of the site craftsmen were either performing equipment a.
storage maintenance or cleaning the various work areas which were not adequately cleaned prior to the shutdown. With the current site staff (140 personnel) the inspector noted that the clean up effort should take at least two months. The in-spector observed that CECO is requiring that many of the valves and pipe hangers, which are currently stored outdoors, be moved to a more protective environment.
b.
The inspector observed that CECO is making maximum utilization of heating equipment (i.e. auxillary boiler and electric heaters)
to maintain the site building temperatures above freezing. Main-taining temperatures above freezing should assure that the fire protection systems will function in the event that they are needed and provide a more suitable environment for safety-related equipment located threughout the various buildings.
No items of noncompliance were identified.
5.
Exit Interview The inspector met with the staff representatives (denoted in the Persons Contacted paragraph) at the conclusion of the inspection on November 16, 1979. The inspector summarized the scope and findings of the inspection. The licensee acknowledged the findings.
