No violations or deviations were found in this area.
b.
The inspector reviewed the licensee's equipment control procedure as outlined in G-17 and 0-20, Equipment Tagging Procedure.
Several tag out sheets were reviewed and a representative sample of tags were verified to be properly identified and hung.
The licensee does provide for independent verification of tagging under standing order 0-37, Independent Verification of Critical Systems Valve Configurations, which requires that certain safety related systems be given a double valve lineup when coming out of a refueling outage.
The procedure also provides for independent verifi-cation on other plant startups when called out on FC-84 and approved by the PRC.
Procedure 0-20 does not specify requirements for inde-pendent verifications, and it is not OPPD's practice to do so for individual maintenance and surveillance items.
This issue is being addressed by the NRC in its position outlined in NUREG 0737, item I.C.6, and by OPPD in their response that took exception to this position.
The regional inspectors have requested clarification of this matter as well as guidance in the application of section 5.1.5 of ANSI N18.7-72 as it pertains to independent verification.- Pending resolution of this question by NRR, the inspector has no further com-ments on the licensee's method of independent verification.
No violations or deviations were found in this area.
c.
The inspector reviewed the licensee's preventive maintenance program as described in procedure M-2, Preventive Maintenance Program.
The master Preventive Maintenance Schedule and one of the craft PM schedules (with the associated computerized cards) were reviewed and discussed with plant personne.
.
No violations or deviations were found in this area.
d.
The inspector reviewed the licensee's administrative controls for special processes to ensure that only qualified procedures and per-sonnel were being used.
The inspector selected two welding procedure specifications for review and evaluation.
The two welding procedure specifications contained the necessary information and approvals.
OPPD Weld Procedure Specifi-cation No. 3, revision 3, dated February 26, 1979, had been approved by the Maintenance Supervisor and QA Engineer and covered manual weld-ing to the GTAW Welding Process.
OPPD Weld Procedure Specification No. 1, revision 2, dated June 23, 1976, had been approved by the Maintenance Supervisor and the QA Engineer and covered manual welding to the SMAW Welding Process.
The inspector reviewed the following NDE Procedures: Liquid Penetrant Examination Procedure (QAP #11) dated April 25, 1977 Ultrasonic Thickness Measurement Procedure (QAP #12) dated Sept-ember 30, 1977.
Magnetic Particle Examination Procedure (QAP #13) dated April 25, 1977.
Visual Examination Procedure (QAP #22) dated February 28, 1980.
Each of the above procedures provided the necessary instructions and information for a qualified Level II or properly supervised Level I to pe: form the specified actions.
l The inspector reviewed Fort Calhoun. Station Unit No. 1 STANDING ORDER N0. G-12, Special Process Control and STANDING ORDER NO. G-26, Main-tenance Quality Control Program.
Each of these STANDING ORDERS (Procedures) provided the necessary instructions to implement the l specified actions to be performed.
A review of Standing Order No.
l G-12, Special Process Control, issued on October 16, 1979, other l related procedures and discussions with licensee personnel resulted l in a determination that qualified procedures were used for each identi-fied special process performed on Critical Quality Elements.
The l approved and qualified procedures specified prerequisite requirements
6.o be used during the process.
Procedures specified environmental conditions, equipment, instrumentation, and personnel who were to be involved in the process.
! Personnel to be used during the special processes were required to be f qualified according to applicable codes and standards required for the specified special process.
Procedures required that the licensee approve the qualifications of contractor / personnel.
The inspector l
' .
reviewed the qualification records of one of the five licensee quali-fied welders.
The welder, Symbol K, had been qualified to ASME Section V, for the TIG process on June 22, 1978, and for the 01AW process on May 9, 1978.
Licensee records indicated that each of the five welders had met qualification requirements by welding within their qualification areas at intervals of less than ninety days.
Licensee procedures require a current listing of (1) Special Processes; ! (2) approved, qualified procedures; (3) qualified personnel and the Special Processes to which these personnel are qualified; and (4) con- ' tractor personnel approved and qualified and the Special Processes which these personnel are qualified to perform, Licensee procedures
specified requirements to assure that procedures and personnel have ' been qualified to perform the functions specified by the Special Pro-cesses.
The responsibilities have been assigned by designating a
responsible individual by job title, who is required to assure that the Special Process is performed in accordance with the stated requirements.
The inspector selected three completed packages containing data and i information related to the installation of seismic restraints required by IE Bulletin No. 79-14.
Each of these seismic restraint installa-tions was documented and installation verified by the following: ' Maintenance Order No. (selected Nos, were 7968, 7973, and 8088) Maintenance Procedure and revision verification Design package checklist Original drawing or appropriate layout sketch Welding and Test Control Record Non-destructive Examination information.
A seismic restraint in the process of being installed was reviewed.
The Maintenance Order, No. 7732, was issued on November 3, 1980.
A pipe restraint (SIS-196) was being fabricated for installation on SIS piping.
The documentation package indicated the present status ' of the fai;rication of this piping restraint.
No violations or deviations were found in this area.
Weld Materials The inspector observed that weld filler material was stored in accordance with approved procedures ~, that each type of filler material was separated from other types of filler material, and that all filler material was in locked storage.
Loose filler material was segregated . -_
' .
according to rod diameter and heat and lot number.
The QC inspector had control of filler materials and custody of the keys to locks.on the cabinets and oven that contained filler materials.
The inspector reviewed selected completed Weld and Test Control Records, Form FC-145, showing the issuance of filler materials.
Applicable , sections of this Control Form had been filled out and signed and l dated as required by Standing Order No. G-12.
' The document package for a pipe restraint under fabrication in Room . 21 was determined to meet requirements specified in Standing Order No. G-12, when this document package was reviewed by the inspector during a plant. inspection tour on December 16, 1980.
Inspection of Pipe Restraints, Wali and Floor Support Structures and Review of Selected Installation in Progress On December 16, 1980, the inspector toured the following plant con-trolled areas: , Plant Area Description of Work or Installation Inspected Room 4 Observed the UT depth measurements being performed by a qualified QC inspector on four -inch diameter Hilti anchors (studs) installed in a seismically designed wall.
A support plate for an appropriately designed seismic restraint is to be installed in this area for Seismic restraint No. ACS-37.
Room 4 Visually inspected three overhead seismic restraints and three seismic supports on piping.
Two of these seismic supports included saddle welds to the attach-ment plates.
