J Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (373/80-40-01; 374/80-26-01): RII7 request for a 100% re-evaluation of previously designed and installed hangers and restraints based on the recently revised program provisions. The inspector reviewed the S&L Project Instruction PI-LS-22, "S&L Divisional Interfaces to Complete the Design of 2-Inch and Smaller Seismic Process and Seismic Instrumentation Piping", Revision 3, dated September 3, 1980, and considered it to be acceptable.
(Closed) Unresolved Item (373/80-40-02; 374/80-26-02): The NSC design flowchart and inter and intra organizational interfaces had not been established.
During inspection at S&L, the inspector reviewed NSC QUAD-7-80-039, " Work Instruction for NSC - Field Activities", Revision 7, dated December 17, 1980, where Exhibit 5 contained "NSC - Field ECN Flowchart", and Exhibit 6 contained "Small Bore Work Flowchart". The inspector has no further questions.
Functional or Program Areas Inspected In conjunction with RIII Reports No. 50-373/80-48; 50-374/80-30 and the li-censee's stop work order of RCI CRD system design and installation activities, the inspector performed followup inspections at RCA, EES, the site, and S&L to observe corrective actions and the progress being made towards lifting the stop work order.

Inspection at RCI on January 12-14, 1981 The inspector reviewed the RCI QA manual and some of the implementing procedures including:
WP-100, " Welding Procedure for Mild Steel to Mild Steel for CRDHS Fabrication and Installation", Revision 2, dated November 12, 1980.
WP-200, " Welding Procedure for Stainless Steel to Mild Steel for CRDHS Fabrication and Installation", Revision 3, dated November 11, 1980.
WP300, " Welding Procedure for Stainless Steel to Stainless Steel for CRDHS Fabrication and Installation", Revision 2, dated November 12, 1980.
WP-600, " Weld Repair Procedure for CRDHS Fabrication and Installation",
Revision 1, dated November 12, 1980.
QAI-8-2, " Installation Procedure for Component Support", Revision 0, dated December 4, 1980.
QAI-10-1, " Instruction for QC Inspection", Revision 0, dated December 4, 1980.
VE-10, " Visual Examination Procedure for Structural Steel Welds - Component Supports (ASME III - NF)", Revision 1, dated April 14, 1980.

QAI-6-3, " Instruction for Document Transmittal for Approval", Revision 0, dated December 4, 1980.
QAI-3-2, " Instruction for Drawing Changes", Revision 0, dated December 4, 1980.
QAI-3-1, " Instruction for Interfaces Between Engineering and Stress Analysis", Revision 0, dated December 19, 1980.
QAI-3-11, " Instruction for the Recommended Format of the Stress Analysis Report", Revision 0, dated January 9, 1981.
RDSA-1, " Procedure for Review of Design or Stress Analysis Reports Submitted by Vendors or Subcontractors", Revision 0, dated December 4, 1980.
As a result of the review, the inspector commented that, prior to the lifting of the CECO stop work orders, the following areas should be clarified by RCI:
a.
Personnel authorities, duties, and qualification requirements.
b.
Training program implementation prior to safety related work activities.
c.
Formal training program to maintain personnel proficiencies, d.
Design manuals to contain design bases and methods.
e.
Acceptable tolerance for suspension system installation and Quality Control inspection.
f.
Hanger inspection detailed checklists.
g.
Walkdown procedure to document existing installed CRD system conditions.
h.
Verification of effectiveness of document control systems.
'
i.
WPS and PQS for P-1000 Unistrut material.
j.
VT procedure to include specific QA inspection checklists and acceptance criteria.
2.
Inspection at EES on January 15, 1981 The inspector reviewed the following manuals and procedures:

.*
EES80010, " Criteria and Instruction - La Salle County Nuclear Station, Units I and 2 for RCI, Inc., San Jose", Revision 1, dated October 22, 1980.
EES Nuclear QA Manual,Section II, Nuclear QA Program, Revision 1, dated August 11, 1980.
After the review, the inspector stated:
a.
The personnel qualification and performance evaluation program appeared acceptable.
.
b.
The design basis for Unistrut structures should be based on actual tests. The RCI representative indicated that destructive tests for Unistrut P-1000 material were unde rway.
3.
Inspection at the Site on January 19, 1981 The inspector reviewed licensee correspondence, including:
RCI QA Manager letter RKC-01, dated January 8, 1981, to CECO Director of QA, subject: Approval of LS-1, Revision for La Salle County Nuclear Station. The document transmitted was Addendum LS-1 QA Manual for LACS Specification J-2922, dated December 1, 1980.
RCI Engineering and Construction Manager letter, dated January 8, 1981, to CECO Station Construction Department, subject: Document Transmittal in Response to RCI Action Item List. The documents transmitted included 14 Nondestructive Examination Personnel Qualification Manual procedures (NDEPs), QA Instructions (QAIs), Review of Design or Stress Analysis
'
procedures (RDSAs), QC Inspection Personnel procedures (QCIPs), and WPs.
The licensee representatives stated that they had not reviewed and accepted the RCI procedures.
In discussion, the licensee stated their intention to allow partial lifting of the RCI stop work at the site for performing walkdown inspection and documentation of the existing system configuration and conditions. This activity will be carried out after procedures approval and the completion of required personnel training.
The inspector was in concurrence with the licensee approach in resolving the problems.
4.
Inspection at S&L on January 22-23, 1981 The inspector reviewed the S&L PI-LS-15, " Processing of CECO NCRs a.
and S&L ECNs", and had no adverse comments. The inspector also reviewed all ECNs applicable to S&L Specification J-2922, " Reactor Internals Installation and CRD System Erection, LSCS, Units 1 and 2", Revision CA, dated September 13, 1976 and considered the docu-ment control to be acceptable.

The inspector reviewed S&L calculation and design of the CRD hydraulic coa rol unit support frames including:
(1) S&L Calculation 38A, "CRD Hydraulic Unit Support Framing",
dated November 13, 1980. The calculation consisted of statis analysis based on peak acceleration at the floor elevation.
(2) S&L Drawing S-1333, " Reactor Building CRDHCU Frame Support at Elevation 761'
0", Revision B.
No problem area was identified as a result of the review.
Exit Interview The inspector met with the licensee representatives at the conclusion of each inspection. The inspector summarized the purpose and findings of the inspection.
