Dear Mr. Broughton and Dr. Long:
SUBJECT: NRC INSPECTION REPORT NOS. 50-289/93-13 AND 50-320/93-06
This letter transmits the findings of the resident safety inspection conducted by
Ms. M. Evans and Mr. D. Beaulieu from May 11,1993 - June 21,1993, at the Three Mile
Island Nuclear Station. The inspectors based these findings on observation of activities,
interviews, and document reviews and discussed them with Mr. T. G. Broughton and other
members of your staff at the conclusion of the inspection period. Inspector observations
indicated safe and conservative operation.
During the inspection period, a valve mispositioning event involving a building spray system
flow instrument was discovered. The mispositioning did not affect the operability of the
building spray system. However, we are concerned that there have been several recent
instances where Instrumentation and Controls technicians have not properly returned
equipment to service following maintenance or surveillance activities. We understand that
you are performing a formal root cause analysis to determine if the incidents have a common
root cause so that appropriate corrective actions can be taken. If this understanding is not
correct, please contact me promptly.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and
its enclosures will be placed in the NRC Public Document Room. We appreciate your
cooperation.
Sincerely,
g ;,u e ., -
A. Randolph Blough, Chief
Projects Branch No. 4
