- (3 ., ,[ /, j 0 6 MAR 1980 MEMORANDUM FOR: C. E. Murphy, Chief, RC&ES Branch, RII FROM: Uldis Potapovs, Chief, VIB, RIV SUBJE.CT: CDR FOR CATAWBA AND BELLEFONTE (AITS F02500065 and F26050F4)
An inspection of Thermxchanger, Inc., was conducred on December 17-18, 1980 and items 1 through 5 of your memo to Thornburg dated February 8, 1979 were included in the inspection plan. The final paragraph of the above memo sug-gested that VIB inspect the implementation of Delaval's QA program. This was accomplished and the results reported under Docket No. 99900334 on a routine basis by the assigned VIB inspector.
The results of the inspection of Thermxchanger's QA program are covered in Report No. 99900700/79-01, copy attached. The response to your concerns identi-fied in the above mentioned memo are as follows:
Item 1 It was verified that vendor was applying the authorized ASME stamp prior to hydro and a citation was issued. However, review of the QA/QC documents and the ANI daily log book, established that the ANI had witnessed the hydro and found it acceptable prior to signing the data reports. The hydros were repeated at a later date for the TVA inspector.
Item 2 This item could not be confirmcd. lecause of the inconsistencies which are noted in TVA inspection report number 9, dated 4-25-77, and inspection report number 10, dated 4-29-77, it cannot be determine: shether or not a problem exists. On page 1 of report number 9, the inspector stated that he had inspected the weld seam and weep holes and no leaks were noted. However, on page 2 of report number 10, he apparently reverses himself by stating that no gaps or weef holes were pro-vided in the unit reported in report number 9 dated 4-25-77.
In the absence of QC/QA documents concerning this issue, you may wish to verify whether weep holes were or were not provided, and if not why did TVA accept the unit at receiving inspection.
It appears that TVA may lack adequate procedures to require its source inspectors to resolve or close questionable items identified by them. If such items are not closed, justification should be provided for accepting these items at the plant site.

Item 3 This appears to be unique with the TVA inspector, since Subsection ND at para-graph ND 6116, permits a specified amount of machining to be performed after hydro.
Item 4 Both ites (3) and (6) are contract violations rather than deviations from the code or 10 CFR 50 requirements. If TVA wishes to resolve these items they will do so through legal action.
Item 5 During the inspection, the radiograph, View 9-10, girth 1, was reviewed, to-gather with the shooting sketch and reader sheet. The reader sheet had been marked " crack or lack. of penetration" and subsequently erased. The area was re-readiographed as requested by the TVA inspector. The " crack or lack of penetration" was identified by the level II interpreter as a film artifact.
The NRC inspector verified that the initial interpretation was indeed an arti-fact by reviewing both the original film, and the film of the re-radiograph of the questionable area.
This is another example of where the TVA's source inspector is doing a good job in everything except properly closing the items or questions he opens in his reports. You may wish to follow this matter as appropriate.
In our view, this memo, together with the above referenced reports will close the subject action items. If you have further questions, please call.
