Inspection Summary:

Inspection on May 15-18,1979 (Report No. 50-498/78-08; 50-499/79-08)

Areas Inspected: Routine, unannounced inspection of construction activities

-

including review of procedures and instructions; observation of work; and

review of records related to fabrication of reacter coolant system support

columns for Unit 2.

The inspection involved twenty-four inspector-hours by

one NRC inspecter.

Resul ts : Of the three are:s inspected, one apparent item of noncompliance

was identified in one area (infraction - failure to have a procedure for

monitoring welding operations - paragraph 3.b).

2.

Site Tour

The IE inspector toured the site to observe construction activities in progress

and to inspect housekeeping.

No items of noncompliance or deviations were identified.

3.

Reactor Coolant System Support Columns

a.

Review of Procedures and Instructions

The IE inspector reviewed the PDM shielded metal-arc Welding Procedure

Specification (WPS)77-716, Revision 0; the Postweld Heat Treatment

(PWHT) Procedure HT-2, Revision A; and supporting Procedure Qualifica-

tion Report (PQR) 77-71, dated November 2, 1977.

The documents were

reviewed for compliance with the requirements of ASME B&PV Code, Section

III, Division 1, Subsection NF,1974 Edition including Addenda through

Winter 1975 and Section IX,1974 Edition including Addenda through

Winter 1976.

These codes were soecified in STP Specification

1C11955035-G for fabrication of the eighteen Reactor Coolant System (RCS)

support columns for Unit 2 under Contract 19744.

In the areas inspected,

no discrepancies were noted between the requirenients specified above and

the PDM procedures and supporting qualification report.

.

No items of noncompliance or deviations were identified.

b.

Observation of Work

The IE inspector observed the work activities of PDM during fabrica-

tion welding of the first nine RCS support columns.

The IE inspector

observed the fitup of RCS support column beam Al-4 to base plate

Cl-12 identified as weld seams 24, 25 and 26 on Drawing l AB, Revision .

O.

Welding was observed being accomplished on RCS support columns

AA-4 and AA-7 using WPS77-71b.

The backgouged root areas of the

gusset plate welds on column AA-4 were observed being magnetic particle

examined by PDM QC personnel.

The IE inspector noted that monitoring of the welding operation was

being accomplished by PDM QA personnel as required by paragraph 5.11

of the PDM QA manual.

The IE inspector requested the monitoring

procedure for review and was informed by PDM QA personnel that the

monitoring of RCS support welding operations was being accomplished

using a monitoring program that was not documented in any instruction

or procedure.

This noted failure to have an approved procedure is an apparent item

of noncompliance, in that, activities affecting quality are not prescribed

by documented instr uctions or procedures as required by Criterion V of

Appendix E to 10 CFR 50.

c.

Review of Records

The IE inspector selectively reviewed the certification documentation

for ten pieces of plate material for the RCS support columns and two

sizes of welding el 2ctrode for compliance with ASTM A588 Grade A or

B and ASME B&PV Code,Section II, Part C, Specification SFA-5.1, Type

E7018, respectively.

In the areas inspected, no discrepancies were

noted between the material certifications and the requirements of the

specifications.

Nu items of noncompliance or deviations were identified.

4.

Exit Interview

The IE inspector met with licensee representatives (denoted in paragraph

1) at the conclusion of the inspection on May 18, 1979.

The IE inspector

sumnarized the purpose and the scope of the inspection and the findings.

A licensee representative acknowledged statements of the IE inspector

concerning the item of noncompliance.
