l LIMITED TEST PROGRAM - ZIMMER 8/24/81 to 9/4/81 Packground The Zimmer investigation has shown that a breakdown in Quality Assurance (QA) occurred in multiple areas during construction.

It has also identified hardward deficiencies in several areas.

In other areas the breakdown of the QA Program indicates that hardware deficiencies may exist, but specific deficiencies have not been identified. The licensee is performing an extensive Quality Confirmation Program to determine the quality of plant construction.

This program is expected to take about eleven months.

In the period of 8/24/81 to 9/4/81, the NRC will undertake a limited program to determine if hardware deficiencies exist in areas where the QA records are missing or are questionable.

The licensee has agreed to provide services under NRC direction and observation to accomplish this program. NRC will select all samples and have them analyzed at Franklin Research in Philadelphia.

It must be pointed out that the failure to identify hardware problems in this limited test program does not mean hardware problems do not exist.

The NRC limited program is presented below.

Material Traceability - Diesel Generator Room 1.

For pipe with no heat number a.

Select three pipes at random b.

Take two sections from each piece (six sections total)

I l

c.

Have six sections analyzed for; (1) Haterial type (2) Material composition (3) Hardness I

(4) Tensile or burst strength (to be determined after discussion with Franklin Research l

L n.

(f

(

l 2.

For pipe with incorrect heat nu=bers; a.

Select 12 pipes at random b.

Trace heat numbers back to manufacturer and determine suitability for this application.

Welding Problems 1.

In an area in which Resident Inspector has identified lack of weld rod control as evidenced by uncontrolled weld rod lying,around, identify six welds whose records do not establish weld quality.

2.

Radiograph these six welds.

Radiography to be witnessed by NRC and radiographs to be read by NRC.

3.

Obtain boat sample from each weld and analyze for material c'omposition.

4.

Determine six socket welds whose records do no identify weld quality.

5.

Radiograph these six socket welds.

Radiography to be witnessed by NRC and radiographs to be read by NRC.

Nonconformance Report (NR) Voiding 1.

Select the NRs discussed in Section 4.1 of the investigation report.

2.

Make a field examination to determine if each nonconforming condition still exists.

a.

If it does not, determine if corrected condition is satisfactory.

l b.

If it does, make a qualitative engineering evaluation of the nonconforming condition and determine its effect on plant quality.
