In our review of the pr'oposed Valve Availability Improvement Program which we

' conducted on September 7, a number of different approaches were proposed for dealing with the valve availability problem on a more global rather than specific cause and effect basis.

l In order to get a handle cn this problem, I believe that we should proceed as 1

! follows:

i

1. Initiate action at the interdepartmental level to improve our knowledge of the l - failures which are occurring in the field through improved reporting and NO l

followup methods.

Daft, Exh. For ID N heve asked Frank Fahland to work with Dick Kosiba in attacking Pff;-Exh:-hhEri this problem at the Department level. However, your engineen, who are responsible for valve problems should develop and use their own OM MOE N OM avenues for acquiring detailed knowledge of what's happening to their equipment in the field (establish appropriate on. site contacts. Doyle Reporting fac.

travel to the site when it appears that a trip will provide useful information, etc.). ._,. S3

2. Establish a valve categorization and failure matrix similar to that which we /

discussed on September 7, 1978.

Usicg the matrix developed in item 2 above, detennine the essential characteristics

3. .

of the valve failure problem (type, applicatiort, site, etc.) and what action is appropriate for us to take to help us meet our valve LCD goal.

' It may be that an FOAK valve design project. such as that recomended

.]

" in our September 7 meeting, will be appropriate; however, I have not - - -

reached that conclusion at this time. I a:2 convinced that we tieed l

l to do a little harder digging to determine the nature of our valveThis problems and use this infonnation as a spring board for action.

8 needs to be done without delay as it is clear that our valve LCD

~

! problem is not.a negligible one.

l  !

Your personal attention will be required to come up with a program that materially

(:,

aids resolution of this problem.

f

. please let Frank Fahland and I kncw by Thursday, September 14. when you will be in -

a position to discuss a revised approach to the valve proble:n.
