Action on Previous Inspection Findings (Closed) Deviation (Rcport No. 78-02): Penetrant testing was not in accordance with ASTM E-165. The procedure, P69044, formerly 7.48, has been revised to comply with ASTM E-165-75.
(Closed) Deviation (Report No. 78-02): Records of past performance of NDE inspectors were not maintained. The records have been updated to include evidence of past performance.
(Closed) Deviation (Report No. 78-02):
Balances were not calibrated.
The analytical balances in question have been added to the calibration program and a complete review of the entire shop has been done and some twenty-three (23) new items were added to the calibration program.
(Closed) Deviation (Report No. 78-02):
Implementing records procedures did not address all requirements of ANSI 45.2.9 and the QA Procedure.
The procedure XN-NF-365 has been revised to address the requirements of a vault description and method of verifying records received.
). n\\4 o,n C, o
3 (Closed) Deviation (Report No. 78-02): Required preventative action was not established. The required preventative action has been established and implemented. The DMR log and an open items list have been modified to identify preventive action and the status of the preventative action.
~
(Closed) Unresolved Item (Report No. 78-02): Radiographic qualifiestion data was not available. The qualification records we:e made available and reviewed.
(Closed) Unresolved Item (Report No. 78-02):
An inconsistency in the handling of radiographs as rec.ords. The inconsistency in the procedures was resolved by revision of one procedure and clearly establishing radiographs as not records.
C.
Document Control 1.
Objectives The objectives of this area of the inspection were to verify that:
a.
The fuel manufacturer's document control system for design, manufacturing, and quality assurance documents is consistent with Regulatory requirements.
b.
The documeat control system includes all drawings, specifi-cations, procedures, instructions, etc. which affect quality.
/
2.
Method of Accomplishment The preceding objectives were accomplished by:
a.
Review of the Exxon Topical Report, XN-NF-1A, Revision 2A, Section 6.0, Titled " Document Control", which establishes the general requirement for document control.
b.
Review of the Parts List, QC Standards List and Process Specifications Index, for a recent project which established a sample of 24 drawings, specifications, and procedures.
c.
Review of the distribution records for the above documents, which establ:'.shed a sample of the work locations where the above documents were in use by 3xxon personnel.
