Dear Mr. Martin:

During the recent inspection (Reference 1) of the Duane Arnold Energy Center's (DAEC's) program developed in response to Generic Letter (GL) 89-10, " Safety-Related Motor Operated Valve (MOV)

Testing and Surveillance," the NRC inspection team identified several issues affecting the implementation of our MOV program.

Specifically, Region III's assessment identified that " effective MOV program implementation has been hampered by limited management attention, and a lack of focus, team work and attention to detail."

The purpose of this letter is to provide our response and describe our corrective actions.

Additionally, we are submitting our revised GL 89-10 Program Plan and a description of our dynamic test scope in accordance with the commitment made in Reference 2.

Subsequent to the MOV Inspection, IES Utilities Inc. (IESUI) management reviewed the MOV Program in detail.

Our review included an in-depth evaluation of resources, manpower, program i

structure, barriers to success and applicable procedures.

As a result of this review, significant enhancements have been made to 9403300182 9403'14"'

These enhancements.

include more extensive and focused management oversight, a dedicated staff of 22 engineers, specialists, technicians, procedure writers and administrators and additional hardware resources.

The new MOV team has completed a thorough and detailed assessment of the DAEC MOV Program.

This assessment has led to many improvements including but not limited to:

Planning for a more detailed review of MOV susceptibility to pressure locking and thermal binding under operating and accident conditions.

Stating expectations for the evaluation of test data feedback for parallel train (sibling) valves.

Revising the methodology used to assess operator capability under degraded voltage conditions to be consistent with industry guidance.

Broadoning the scope of dynamic testing.

Incorporating use of Probablistic Risk Assessment (PRA).

The new MOV team has also participated in team-building training to improve its attention to detail and focus.

The new team continues to review its progress, goals and expectations and provide detailed briefings to management so as to ensure successful completion of the program.

As. discussed with members of your staff at a recent NRC-DAEC-meeting on our MOV program, we believe that the changes described above will result in an effective MOV program with substantial improvements in management attention, teamwork and att'ntion to e

detail. ~ An outline of that presentation is included ~as.

We understand that NRC Region III management concurs with:our assessment of the MOV program and the improvements we have implemented.

Additionally, we plan to pursue frequent communications with your staff regarding our MOV program progress.and issues.

This letter also addressos the commitment made in Reference 2, i

" Submit the revised GL 89-10 Program Plan including a revised dynamic test scope".

This. letter transmits the revised GL 89 '

' Program Plan as Attachment 2.

The MOV team is currently revising the scope of valves to be

-dynamically tested.

If dynamic tests are practicable, the new

. scope will be considerably broader in order to further

-substantiate program' assumptions.

After this effort has been completed, the" revised scope of dynamic testing will be-clearly communicated to your staff.

This letter contains no new commitments.

If you have any questions regarding this matter, please fee fi ne to contact my office.
