Ueldine Material Con * ol The inspector reviewed Specification MCP-2-2.
The inspector exanined two velding material issue locations for confernance with requirements of applicable codes and procedures, including the following:
Storage of caterials - identification, segregation, cleanliness.
a.
b.
Tc=perature control.
_
Issue records - approval, amount withdrawn, identity of with-c.
drawer, dates, identification with weld location.
d.
Handling of returned =atc.ial.
Criterion V of 10 CFR 50, Appendix B, requires, in part, " Activities af f ecting quality shall be prescribed by...precedures...and shall be accomplished in accordance with these... procedures...."
United Engineers and Constructors procedure MCP-2-2, Paragraph 3.3.1, requires that the time of weld rod issue be entered onto requisition form THI-WD-3 to effect a mechanism for control of moisture absorp-tion of low-hydroger electrodes which could adversely aff ect the welding process.
The inspector found that the tLae of electrode issuance was not being recorded on the WD-3 forms at either of the
-
two welding material issuing locations.
' This item is considered to be a deficiency with respect to the above requirements of Criterion V of 10 CFR 50, Appendix B.
3.
Defects in Cast Stainless Steel Valves The licensee has reported finding a number of defective cast stain-less steel socket veld valves, r.ost of which were check valves, 2-inch or smaller.
A total of 34 valves had been rej ected, most of which were in the radwaste systems.
The vendor's (Crane Company)
-
.
representative had examined the def ective valves at the site, but had not yet reported his findings to the licensee. The defects (
found were casting voids, linear indications, and gouges.

4.. Containnent Tendons - Interval Betueen Shineine and Groutine
_
The containment tendon prestretsing procedure, "Stressteel Corpora-tion Installation and Field Quality Assurance Procedure," " arch 11, 1975, Section 4.2, specifies a maximum of 7 calendar days between renoval of the tendons f rom storage at Wilkes-Barre (or Olmstead)
and the grouting of the tendons.
The inspector questioned this 7-day interval maximum in view of the difficulties experienced at other locations in staying within specified intervals of 90 days.
The Stressteel representative stated that he was certain that the 7-day maximum interval vould be maintained consistently and, if l
exceeded, test wires would be withdrawn and examined for corrosion.

.
This item is unresolved.

5.
Corrosion Protection of Tendons in Shiement The Stressteel Tendon Installation Manual, Paragraph 3.4.3.1, Tendons Material, states, in part, " Prior to shipping, the material shall be treated with an approved vapor nhase inhibitor in a proce-dure denonstrated by experience or test to be ef f ective, or with other appreved corrosion inhibitor compatible with the use of grout as final protection, placed on reels or in packs."
The inspector asked for specifics on the corrosion inhibiting system to be used, and already used in wire ship =ents from Florida Wire and Cable to Wilkes-Barre.
The licensee agreed to secure this information, and to insure its incorporation into the procedure.
This item is unresolved.

Revisions in Containnent Tendons and L'edce Desien 13.
Resolution:
The inspector had qucstioned the changes in the design of containnent prestressing tendons and wedges. The proposed changes were revieued
'
by the Division of Reactor Licensing, whose response to the licensee, in a letter dated February 25, 1975, stated in part, "Your... analysis is that the codified syst em...can perform its function without inpair-ing the public safety. The staff concurs with this conclusion." This
-
resolves the item in Details, Paragraph 3, of IE Inspection Report No. 50-320/74-07.
14.
Resolution: Cocoosition of Containnent Tendon Grout During a previous inspection the inspector had ouestioned the cor-
'
rosiveness of the proprietary grout used in the containment prestres -
The licensee made available to the inspector a letter sing program.
from the architect-engineer's consultant, dated April 13, 1972, which stated in part, "I can see no need for concern, for your application, in the use of the chemica,1s in the grout."

This resolves the item in Current Findings, Paragraph 2, of IE
