Dear Mr. Parris:
BROWNS FERRY PLANTS, UNITS 1, 2. AND 3
% Fi NUREG-0737 ACTICP ITEM II.K.3.27 (C0fNON REFERENCE LE RE:
Reference:
(a) Letter from L. M. Mills to H. R. Denton dated April 9,1981 We have performed our post-implementation review of your modification (reference (a)) for the subject Action Item. The criteria used in our review were:
1.
All level instruments should be referenced to the same point.
2.
Licensees should comit to modify docununtation, including operating procedures and technical specifications, as required, to reflect the new reference level.
3.
Licensees should comi t to provide appropriate training for plant operators.
Our review did not encompass a human factors evaluation of your water level instrumentation (e.g. placement, legibility, etc.). That evaluation will be perfomed as part of the detailed control r som review (Action Item I.D.1) that you will be expected to conduct per NUREG-0737 and NUREG-0700.
We find that, while your modification is an acceptable interim measure with respect to the July 1, 1981 implementation date, it does not completely resolve the concern upon which this Action Item is based. The rationale of Action Item II.K.3.27 is that the operator should not have to perfom mental interpolations to understand what a reading on one water level indicator means relative to a reading on another water level indicator.
Your modification makes infomation readily available that the operator needs to perfom a mental interpolation, but it does not eliminate the need for perfoming the interpolation.
