MEMORANDUM FOR

FROM: R. G. Taylor, Reactor Inspector, Wolf Creek Construction

Task Force ,

{

' SUBJECT: ALLEGATION FILE 4-84-A-55

The file indicates that tN alleger made . allegations initially to the

Kansas Gas and Electric Company in late April or early May 1984. Because the

allegation not only involved the Wolf Creek Station but as

well, the licensee informed Region IV of the situation o'n, ,

Region III' was notified of the situation on May 7',1984, a' rid their

subsequent' investigation was unable to either refute or substantiate the

allegation but did find that it had little or no merit in regard to plant

l

safety.

l The allegation, as understood by Region IV, was that pipe support hangers _

and/or components within supports did not,,in many instances, have " heat

'

numbers" marked on them at the time of:  : examination of them and that these

numbers were later added or post applied. '0I:RIV interviewed the alleger on

) May16,1984,where] apparently reiterated, concern about finding

" numerous" hangers CTith'out heat numbers but also stated that believed the

missing numbers were added later but had no specific knowledge that belief

was true and could provide no specific information about the hangers involved.

The NRC inspector has reviewed the KG&E Quality First team investigation file

'

pertaining to the allegations as originally received by them. Two of the four

documented " concerns" were found to be similar in context to Region IV's ,

understanding of the allegation. The Quality First file indicates that there

was a followup on the alleger's concerns using hanger walkdown logbook

wherein the alleger acoarently recorded specific observations that led to

,

% conclusions and % concerns.

The report on each logbook reflects the observation and a date of the ,

! observati,on which range from November 1983 to March 1984. (Note: One outrider

date of, was recorded and is apparently an error on the

{ . , _

alleger's part or on the transcriber's part since the alleger was not employed

g

l at that time.) The KG&E followup was initiated not earlier than May 1984 and

was concluded in September 1984. In every instance, the followup revealed that

'

i

, the alleger's specific observations were no longer valid in many instances with

material changes or engineeri1g actions which clearly took place after the

-

original observation by the alleger and apparently prior to the Quality First

follewup. The Quality First team conclusions was that the allegation was not

substantiated because they did not confirm ' observations. The NRC

inspector, however, would conclude that the allegation was substantiated but

taken in the context of today's time frame, has little technical merit.

Following the initial walkdown performed by' craft

personnel that the alleger was involved in,'there have been at le'ast two more

major walkdowns. One was by KG&E QC and the other by Bechtel personnel for the

purposes of satisfying IEB 79-14. Each found problems with various aspects of

traceability of components that were resolved on a case basis. A similar

allegation case (4-84-A-98) was inspected as documented in Inspection

~ Report 50-482/84-58 with the same conclusion. It is thus apparent that there

were many instances of failure to follow detailed QA/QC procedures during the

fabrication and installation process. After identification of the problem it

is also apparent that KG&E instituted an effective corrective action program as

indicated by paragraph 8A of Inspection Report 50-482/84-23.

The above identified case is considered closed.
