'a.,

[]

F Following our decision of July 10 to require Jersey Central 4 (

to complete nondestructive testing of the piping within the g/

primary coolant boundary and of the safety valves, you instructed.ma to coordinate regulatory inspection and review d

of this work and to assume responsibility for decisions in i

[

regard to adequacy of the equipment in question.

(

l

. g' '-

By letter of July 29 from Dr. Morris, Jersey Central was officially advised of the additional work necessary.

On July 17, I visited the Oyster, creek site in company with Messrs. Gustafson, DRS and Collins, Compliance.

Custafson and Collins remained at the site until July 18, at which

p:

time ultrasonic and dye penetrant testing of the remaining pipe in the containmerit_ was completed.

Results of the tests f

were favorable and on July 19 I advised G.E. that the work on the piping had been satisfactorily completed.

7 i

Meanwhile, I had proceeded to San Jose, California to observe the tests being made on safety valves.

Reinmuth of Compliance

~

accompanied me on this trip.

General Electric had on hand

[VM" *Q^,a in San Jose some 55 valves of the type then installed at-6 3

Oyster Creek and had initiated on July 15 a program f6r p> a:

jO

... radiographyof the valve body castings.

I reviewed the W,

7p; :,&p ~ ' progress of the work at San Jose on July 18 and at X-Ray

.y j'<

Engineering Company, San Mateo, California where the This review continued gl yp radiography was perfomed, on July 19.

fomulate, in wtiting, a set of acceptance standards, and Q;p bases therefor, for the castings.

1 returned to San Jose on July 28, accompanied by Colline.

0.

ph T1 By that date approxbsstely 29 castings had been radio-(N, f..

graphed and evaluated by CE.

The valves associated with

. "^

, py,

a these castings had been reassabled at San Jose and about i7 V*

20 valve assemblies had been shipped to Dresser Industrias C

in Imuisiana for valve ca11bration.

By this date General t.

Electric had fomulated acceptance standards and had

b

- selected 16 valves for service at Oyster Creek.

Mr. Collins reviewed a number of the radioEraphs and confined GE's

/.

evaluation.

By CE's standards they had rejected 11 of the 1,

4 first 29 castings ew=ninad.

GE's proposed acceptance K

. standards were satisfactory and on the afternoon of July 28, y

i I apprwed the 16 valves GE had selected for installation v,.,

at Oyster Creek.

GE infomed us that they plan to radio-g graph the remainder of theesstings on hand at San Jose and 1

to call in all safety valves then at the Dresden, Quad Cities, Monticello and Millstone sites and to radiograph those i.

castings.

For the turnkey plants at the sites just mentioned, GE proposes to select valve castings by the same standard r

as used for Oyster Creek.

I feel that this is a satisfactory proposal and recommend that GE be so advised.

With regard to the other items mentioned in Dr. Morris' letter p

of July 29, I determined on July 25, from information obtained by the Division of Compliance, that the steam line isolation

?

valves had been satisfactority tested and so infomed the licensee on that date.

On July 29, I ascertained from f

doctamentation produced by GE in San Jose that the two 18" k.!

feed water valves and carbon steel fittings in the reactor i

coolant pressure boundary had been satisfactority esamined.
