CASE Questions About Reports j

Dear Mr. Grimes:

CASE reviewed a portion of the NRC. reports processed 11n-1989-and icaued prior to fuel load authorization. -As a result of the review, CASE has;the following questions for the NRC' I i

-_j j

LIn: regards to Inspection ' Report 19_M5]AM-19/_83_-QR)' Dated 1/1Q/11Q CASE has the fol1owing questions:

~

a. Did TU Electric's evaluation determine whether a breakdown.

occurred in.the vendors-QA Program, thus, fallowing. deficient-tube steeix to be shipped-to site? ,

b. CP-89-01 Contamination problems were found inside NAMCO switches.in 1989.  ;

Contaminants-were also'found and reported in'1979.'in NRC-Bulletin '

79-28. Were such deficiencies.in the manufacturing-process-and QA  :

controls ~ investigated at~NAMCO?

k

c. CP-89-20 I Why were unauthorized _ mounting bolts installed in'Limitorque l actuators? 'I

d. Were the above deficiencies caused'by a deficient TU Electric ,

vendor surveillance program?- .!^

e. Allegation OSP-89-A-0080 1 Does the NRC statement about the SAFETEAM findings, (" destroying ,

, old records " and " the bulk of the documentation has been reviewed and corrected") mean that some records may have beeir .!

inappropriately destroyed but the bulk were accounted for in some  !

way'(reconstructed)?

In regards,to Inspection Report 50-445fAAS-AS/S4-04_ Dated.J2/21/89

• CASE has the following questions:

This NRC report documents a deficiency and a violation concerning cable grips and the potential for damage to Kapton. NRC letter to CPUR dated-January 30, 1990 addresses the use of Kapton, under normal and-transient conditions and included a statement about the flashover incident at Comanche Peak (9/29/89) which " destroyed" several wires,

a. Did the NRC close these issues without assuring that all possible mechanical interactions between Kapton and other items were eliminated.

b. Did the NRC close this issue without addressing the mishandling  !

of Kapton during installations?

c.

Accordingly, can the NRC be sure that TU Electric adequately addressed all Kapton issues?1 In regards to Inspection Report 50-(_45/446-89]l3-13 Dated 2/?L9Q. CASE has the following questions: i On page 3, 4, and 5, the NRC closed the open item on AIRCOM fasteners.

CASE questions to the close are as follows: i

a. Were all samples randomly selected?

b. Was the sample size statistically valid?

c. Did the random sample cover all timeframes when counterfeit boltu could have been supplies?

i

d. Were all bolts accessible and included the random sample?

e. The NRC acknowledged that minor deviation from-specifications occurred. What is the technical basis that they were minor?

i

f. Because of the peculiar circumstances surrounding AIRCOM fasteners, justified?

how can anything less than 100% inspection / testing be  ;!

We look forward to your reply. If you have any question please contact me at ( 414 ) 7 31-1917 o r Mrs . Juanita Ellis, The President of CASE, at (214) 946-9446. .

CASE Attorney km ICASE understands that TU Electric originally contended that there were no problems with Kapton. Also the NRC had to exert pressure on Tu Electric to address the issue.
