AUDIT HT-G-80-12, DEFICIENCY NO. 1 On July 31, 1980, TVA notified NRC-0IE Region II, Inspector R. W.
Wright, of a potentially reportable condition under 10CFR50.55(e) regarding inadequate drawing control at the Hartsville Nuclear Plant.
This is the first interim report on the subject reportable deficiency.
The final report will be forwarded to you by November 19, 1c80.
Description of Deficiency The TVA CONST OA Unit at Hartsville performed an' audit of drawings, being used on the site. The auditor surveycd 155 drawings maintained by Engineering and Crafts. The audit revealed 30 drawings which were out of date and/or were superceded by later revisions. A similar nonsignificant audit finding earlier this year had uncovered only 5 of 70 drawings to be similarly deficient.
All of the 5 deficient drawings at that time were maintained by Crafts. The 30 deficient drawings identified in the subject audit were found in both engineering and craft disciplines.
Safety Inclications This condition represents a significant breakdown of the OA program regarding drawing control and, if remained uncorrected, design changes important to safety may not have been implemented (pipe hanger location changes, etc.).
Corrective Actions TVA's Hartsville Document Control Unit (DCU) is generating a list, by computer, of all drawings currently in use and the current revision.
This list will be updated on a daily basis by using the TVA drawing receipt forms processed each day.
The above list will be used by DCU to survey all drawings files onsite to identify and replace any out-of-date drawin6s. The files containing the 30 drawings identified in the audit deficiency have been updated to include the current revisio.ts as of August 22, 1930.
The remainder of the drawing files onsite are presently being surveyed now beginning with OC drawing files.
All files onsite will be surveyed and corrected as necessary by November 7, 1980.
In order to prevent recurrence of this condition, DCU will use the list discussed above to conduct a monthly survey of drawing files including all OC files and 1/3 of all other site drawing files on a rotating basis.
This method will ensure that all site drawing files are reviewed on a quarterly basis. Also, memoranda have been sent from the Construction Project Manager to the Construction Superintendent and from the Construction Engineer to site engineering and QC units stressing the necessity of using up-to-date drawings and requesting that all drawing holders be informed accordingly.
