Dear Mr. Kirsch:

Forwarded herewith is copy of Report No. PAR (DCNP)-NDE-2, November 22, 1983, prepared by Kenneth Ristau pursuant to inspection work at Diablo Canyon last week.

Also attached is a copy of the Project Quality Plan we pre-pared for this acsignment. We routinely prepare these plans for NDE assignments for NRC in accordance with our contractual commitment. Due to the urgency of.this task, the plan was available cnly in draft form to Mr. Ristau and Mr. Hunt before the inspection.

Please let us know if there is anything else required. We look forward to working with you again.

Very truly yours, a

Contract Personnel Assigned Daniel J. Hunt, Wisconsin Industrial Testing, Inc.,

Level II, MT, PT, UT Introduction The NRC outline of work (Exhibit 1) designates 3 welds to be liquid penetrant tested and visually examined.

The 25 stainless pipe welds.to be tested for delta-ferrite measurements were designated by Mr. Dennis Kirsch, NRC Section Chief. For a list of the welds and results of the inspection, see WIT report (Exhibit 3). Also see WIT report for results of visual and penetrant inspection (Exhibit 4).

Mr. Kirsch also indicated the 102 wolds of which radiographs were to be viewed (Exhibit 2).

i e ra me e le r, a c. Report No. PAR (DCNP)-NDE-2 co n sattino ' s uoi n e en s Page 2 atm aeova, wisconsin November 22, 1983 Record of Activities November 15 and 16 inspections were made by Dan ilunt and films were viewed by Ken Ristau. ,

In a short meeting with Dennis Kirsch, day end November 16, the results of our findings were conveyed verbally, as follpws:

1. The delta-ferrite measurements met the NRC requirements.
2. The LPT of all three welds were approved but FWill had one LP indication running transverse to the weld in the base material of the pipe. It was approximately 1/2" away from the weld and about 1" long.

~

3. The radiographs of the welds were viewed and approved as adequately meeting Code. Comments were also made by the writer concerning film quality, detail of reader sheet documentation and the excellent condition of the radiographs, nearly 10 years af ter x-ray date.

Conclusions

1. Having reviewed the radiographs and reader sheets of all 102 selected piping welds identified in Exhibit 2, the
writer found reader sheet documentation detailed and clear.

Radiographs were readily available, in good order and of ,

,very good quality. Radiographs are approved as meeting the requirements of applicable Codes.

2. All 25 welds selected for delta-ferrite measurements met the requirements of Code and Regulatory Guide 1.31 (See Exhibit 3).
3. Visual and liquid penetrant examination of FW110 and 112 were acceptable. FWill weld was also acceptable but an liquid penetrant indication was noted in the pipe base material (See WIT Penetrant Report, Exhibit 4).
