Areas Inspected:
Implementation of 10 CFR 50, Appendix B Criteria and applic-able codes and standards, including action on previous findings, inspection and tests, in process inspection and internal audits.
The inspection involved twenty-nine (29) inspector hor.rs on site.
Results:
In the four (4) areas inspected there were no apparent deviations or unresolved items identified in three (3) areas.
One (1) apparent deviation was identified in the remaining area as follows:
Deviation: Audits - Follow-up corrective actions not taken within the specified timeframe.

DETAILS SECTION A.
Principal Persons Contacted i
R. W. Swayne, Quality Assurance Manager D. P. Gilbert, Plant Manager G. M. Rose, Manufacturing Manager J. J. Chappell, Senior Projects Engineer D. A. Solyan, Contracts Supervisor J. T. Rose, Materials Manager J. Carroll, Authorized Nuclear Inspector All principal persons contacted, attended the exit interview meeting.
B.
Action on Previous Inspection Findings 1.
(Resolved) Unresolved Item (Paragraph F.3.6, Inspection Report No. 99900048/79-01):
Reported allegations.
This item is now listed as an unresolved item in Inspection Report No. 99900053/80-01.
2.
(Resolved) Unresolved Item (Paragraph D.4.b, of Inspection Report No. 99900048/79-01):
Suspected design deficiency of disc tee-heads for 52 line items (136' valves).
The inspector verified that Anchor / Darling Valve Hayward (ADVH) had completed their design review of 136 valves suspected of inadequate design of the disc Tee-head area, except for two (2) valves.
This encompasses all suspected valves that have been shipped.
The material yield strength used in the review of these items was the minimum yield strength given in Section III, Appendix I, of the ASME Code.
Using an allowable stress equal to 90% of the disc material yield strength and calculating both shear and combined stresses in the tee-head area, ADVH has determined that the design for all but 2 valves shipped is adequate.
The maximum differential pressure and coincident temperature against which these valves must operate, has been requested from the customer.
Upon receipt of this information, the stresses in these two valves can be rechecked.
How-ever based on the mechanical properties recorded on the CMTR for the SA 216 grade WCB material from which these two valves were manufactured, it is noted that the actual yield strength of 51 ksi is approximately 140% greater than the code specified ninimum of 36 ksi.
Based on Article III 3210, of Appendix III, of Section III, in ADVH judge-ment, the design of these two valves will also be found to be adequate.

Review of current work loads.
2.
Method of Accomplishment The preceding objectives were accomplished by observing the manu-facturing/ fabrication processes implemented by the vendor, and discussions with the vendor's cognizant personnel.
3.
Findings All previously reported vendor nuclear work load remains the same.
ADVH successfully passed a re-survey by the ASME during the week of March 17, 1980.
ADVH tas been notified that their Certificate of Authorization will be re-newed for three (3) years.
D.
Audit Control 1.
Objectives 4
The objectives of this area of the inspection were to verify that procedures had been prepared and approved by the vendor that pre-scribed a system for auditing which is consistent with the commitments of the ASME accepted Quality Assurance Manual.
Also, verify that these audit procedures were being properly and effectively implemented by the vendor.
2.
Method of Accomplishment The objectives of this area of the inspection were accocplished by:
Review of the ASME accepted Quality Assurance Manual, Section a.
4.4.1 to verify that procedures had been established to prescribe a system for auditing.
b.
Review of the following documents:
(1) Current audit check list; (2) Current audit schedule; and (3) Audit personnel qualifications; to verify that they had been prepared by the designated authority, approved by management and reviewed by quality assurance.
3 Review of audit procedure NQA-011 to verify that it identified c.
the organizations responsible for auditing and their responsibility; established audit personnel qualifications and training and that the audits are performed by these personnel; and established the essential elements of the audit system.
d.
Review of selective audit reports to verify that they identify the written plan, team selection, team orientation, audit notification, pre-audit conference, audit performance, and post-audit conference.
Review of randomly selected audit reports to verify that the e.
distribution to management, and the audited organizatiou, and follow-up regarding corrective action had been accomplished.
f.
Review of internal and external audit reports to verify that the applicable procedures were available to the audit team personnel, and that the audit procedures were properly and effectively implemented.
3.
Findings a.
Deviation Refer to Notice of Deviation b.
Unresolved Items i
None were identified E.
Inspection and Tests 1.
Objectives The objective of this area of the inspection was to verify that the inspection procedures being used by the vendor conform to the requirements of 10 CFR 50, Appendix B and applicable Codes and Standards.
