General Information The NSSS suspension system, including supports for the lines connecting to the NSSS before code classification change, is to be installed and inspected by Babcock and Wilcox Construction Company (BWCC). All other safety-related pipe and equipment suspension is to be installed and inspected by Bechtel Power Corporation (BPC). All safety related suspensions including BWCC installed items are procured, receipt inspected, and stored prior to issuance for construction by BPC.
The NSSS pipe whip restraints installation activities have just begun. The NSSS hangers and the large snubbers for the four Reactor Coolant Pumps and Motors are scheduled to be installed in the later part of 1979. The installation of BOP hangers is an on-going activity. The installation of safety-related snubbers is scheduled for early 1979.
-
/'
The supplier of the safety-related hydraulic anubbers, including the large hydraulic snubbers to be installed on the Reactor Coolant Pumps, is ITT Grinnell Corporation. All safety-related spring and rigid hangers are manufactured by ITT Grinnell Corporation and BPC.
The mechanical snubbers will be supplied by the Pacific Scientific Company.
.
The total number of large Reactor Coolant Pump hydaulic anubbers is 48.
The estimate total number of all the safety-related hangers, snubbers, and restraints for the large bore piping is 8,000, among which 300-350 are mechanical snubbers. To date no hydraulic snubbers are planned to apply to the BOP safety-related piping.
2.
Review of QA Implementing Procedures The inspector reviewed the pipe suspension system design engi-neering and construction QA manuals. Specific review areas i.
included:
QA audit requirements including acope, frequency, criteria, reporting, and followup.
Measures to verify technical specifications, acceptance criteria, and required documentation are specified in design and procurement documents.
Controls of design changes and fie14 initiated design changes.

Review of BWCC Work and Inspection Procedures The inspector reviewed the BWCC "QC Manual", Rev. 6/CPCo, dated August 23, 1978, and also several traveler type work and inspection procedures relative to installation of safety-related suspension systems, with the following comments:
.
a.
There appeared to be lack of work procedures to reflect the requirements of:
(1) material handling and preservation.
(2) reference to manufacturer's recommendations and c.
i, instructions.
(3) final unit and system adjustments.
(4) time period limitation for initiation of corrective measures af ter installation rejected by QC inspection, b.
There appeared to be lack of inspection procedures to include:
(1) detailed inspection item checklists.
(2) timely inspection of installed components to prevent deficiencies from recurring.

.
(3) systematic documentation of installation deficiencies for effective QA trend analysis.
The BWCC and CPCo representatives concurred with the inspector and stated that procedures will be updated prior to instal-lation of snubbers and hangers.
No items of noncompliance or deviations were identified as a result of the review.

Review of BPC Work and Inspection Procedures The following BPC Procedures were reviewed by the inspector:
Project QC Instruction (PQCI) No. 7220/P-2.10, " Pipe Hanger, a.
Support, Restraint, and Shock Suppressor Installation-Initial" Rev. 3, dated August 2, 1977.
r-b.
PQCI No. 7220/P-2.00, " Pipe Hanger, Support, Restraint, and Shock Suppressor Installation - Final", Rev. 3, dated January 10, 1978.
PQCI No. 7220/P-2.20, " Pipe Hanger, Support, Restraint, and c.
Shock Suppressor Shop Fabrication and Rework", Rev. 3, dated April 17,1978.
d.
PQCI No. 7220/W-1.00, " Welding, Heat Treating, and Non-Destructive Examination of Q-Listed and ASME Section III Items", Rev. 4, dated June 30, 1978.
Subsequent to the review, the inspector discussed the work interfaces between crafts, field engineers, welding inspectors, and piping inspectors. The QC inspections of installed hangers
,
are generally conducted within two weeks after installation, and at times, QC Inspection Report (IR) are initiated during QC surveillance. The inspector stated that he found no problem in regard to the timeliness of the QC inspection activities, and that he will audit IR records to verify the consistency of such general practices.
The inspector further commented that the existing pro-cedures do not reference snubber manufacturer's instal-lation recommendations and requirements, and the present procedure checklists do not include sufficient detail to assure complete mechanical and/or hydraulic snubber-5-

- e inspections. The licensee and BPC QC engineers stated that
update of the procedure will be completed prior to snubber installations.
No items of noncompliance or deviations were identified as a result of the review.

Review of BPC Specifications The inspector partially reviewed the following BPC specifications:
a.
7220-M-209, " Technical Specification for Purchase of Pipe Hangers, Supports and Restraints", Rev. 7, dated August 17, 1977.
