-Page.1 of 2 RE0 VEST FOR ADDITIONAL INFORMATION NOTICE OF VIOLATION ITEM A (445/8607-V-24)
...(W)ith respect to NOV Item A, the corrective steps taken'-
appear inadequate in light of the reason given for not performing a technical evaluation of_ all 48 closed Corrective Action Reports (CARS) to. assure that they have been properly-dispositioned.
Additionally, please inform us of actions taken to ascertain whether this problem exists -in CAR systems used by other groups,.
j such as Brown and Root."
RESPONSE TO ITEM A (445/8607-V-24)
In our original response to this Notice of Violation, we indicated that a review of 10 of the previously closed CARS had identified no additional inadequate justifications for closure. We believe:that this result is indicative of the-quality of actions.taken to address previously cicsed CARS, I
and properly addresses the concerns raised.in the violation.
To further demonstrate this, the 38 remaining CARS closed prior to the; action taken to prevent further violations will also be examined. The review has J
been initiated, and'will verify the adequacy of each CAR's' disposition.
I A similar review of the adequacy of the disposition of closed CARS which were issued by other organizations, such as Brown and Root, will also be performed.
The reviews are scheduled to be completed by October 30,.1987..
RE0 VEST FOR ADDITIONAL INFORMATION ITEM E NOTICE OF DEVIATION (445/8607-D-01) l With respect to N0D Item E, please provide the basis for the. statement in your i
February 18, 1987, response (TXX-6222) indicating that the welding on the seismic arrestor brackets has been determined to be acceptable.
Additionally,.
your response identified that your letter TXX-3657 would be supplemented to document why lack of, welding documentation does not constitute a significant q
condition: adverse to quality. TXX-3657 was supplemented by TXX-6526.
Please clarify the statements in supplement, TXX-6526, relative to control' of bracket materials and welding by the valve manufacturer.

Fisher Control's Certificates of Conformance and will inspect the bracket attachment welds in accordance with the visual weld acceptance criteria (VWAC), and the weld sizes as depicted on the vendor's design drawings.
