Safetv-Kelated Components - Review of Quality Assurance Implementing Procedures s.
Receipt Inspections Receipt inspection of safety-related components is required in the construction specifications. This was verified by review of three specifications relating to safety-related components as follows:
Specification Number Title 2323-MS-0049 Component Cooling Water Heat Exchangers 2323-MS-0012 Containment Spray Pumps 2323-MS-00ll Component Cooling Water Pumps These specifications cell for receipt inspections to: (1) examine the packaging and seali*ag of components and spare parts; (2) check that all components under the purchase specifications have arrived; and (3)
check for shipping damage.
Implementing procedures for receipt of safety-related material and
requirements for receiving inspection are contained in CP-QAP 7.2
"QC Receiving Inspection," (Revision 3, March 19, 1979).
144LP' J34
.
Additional specific instructions for " Receiving of Westinghouse Safety Related Equipment" are contained in Brown and Root's QI-QAP-7.2-8.
These instructions require verification of proper W documentation supporting that the components are in compliance with purchase specifications including Data Records (ASME require-ments); that the components are adequately identified (W identi-ication); and that the specified components are damage free.
Items which do not conform to.the specifications are reported under CP-QAP-15.1, " Control of Nonconforming Items."
No items of noncompliance or deviations were identified.
b..
Component Handling and Lifting Safety-related components are to be handled in accordance with Brown and Root Construction Procedure 35-1195-ACP-3, Section 5.2.
Gibbs and Hill Specification 2323-MS-101, " Mechanical Erection," specifies that mechanical components are to be lifted in accordance with the manu-facturer's instructions and/or ANSI B-30 series.
Specific preplanning instructions for rigging and hoisting operations are to be provided on the " Operational Traveler" as required by QI-QAP-13.1-1, "QC Surveillance of Rigging and Hoisting," for safety-related components.
The preplanning is established and approved prior to critical lift-ing operations. Records are to be maintained on pretesting of standard manufactured lifting equipment and components.
c.
Installatmon Activities The acti"ities involved in the setting and alignment of mechanical safety-related components are governed by written engineering
-
instru aions based on vendor instructions along with QC Inspection Reports or by Operational Travelers which combine the Engirieering Instruction and QC inspection documentation into one document.
Disctc; ion with a licensee representative revealed that no procedure had been developed that defines which system is to be used with a given component and therefore, a possibility exists that neither system might be used on occasion.
The above item is considered as an unresolved item pending further review.
d.
Post Installation Cleaning Preservation and Inspection Storage requirements for safety-related components for pre and post installation conditions are specified in Brown & Root Con-struction Procedure 35-1195-MCP-10, " Storage and Storagc Main-tenance of Mechanical and Electrical Equipment," (Revision 4, June 14, 1979).

" Mechanical Equipment Storage Maintenance."
Measures for equipment and equipment storage area cleanliness and preservation and inspection of equipment are established prior to need by engineering on Maintenance Record Cards (MRC).
No items of noncompliance or deviations were identified.
3.
Electrical Components and Systems - Review of Quality Assurance Implementing Procedures The IE inspector reviewed various procedures (given below) in order to determine if appropriate and adequate procedures exist for controlling activities involving safety-related electrical components and systems.
a.
Receipt Inspection, Handling and Storage Requirements for electrical components and material receiving, are contained in Brown & Root Construction Procedure 35-1195-ACP-3, (Revision 7, September 22, 1978) " Material Receiving, Storage and Handling." Items received are to be inspected for damage and conformance to purchase specifications. Results are documented on a B&R "Receivin'g Inspection Report" (RIR).
Specific requirements for handling and storage of the material are contained in ACP-3 and in B&R Construction Procedure 35-1195-MCP-10,
" Storage and Storage Maintenance of Mechanical and Electrical Equipment." Periodic verification that material is properly stored is prescribed on a Maintenance Record Card (MRC) by quality engineering.
Special, as well as general, storage requirements are included on the HRC.
Records are maintained on these activities.
Safety-related equipment is required to be segregated, where possible, and clearly identified by purchase order numbers.
b.
Installation Installation of safety-related electrical components and systems which are " unique" are controlb d under the B&R and TUGC0
" Operational Traveler" systems (B&R CP-CPM-6.3 and TUGC0 CP-QP-2.3, respectively, see paragraph 5).
The electrical Operational Travelers are required to have specific quality requirements and " Hold Points" for QC witness or verification.
