SUBJECT:

Calvert Cliffs Nuclear Power Picat Unit Nos.1 & 2; Docket Nos. 50-317 & 50-318 Revision to Commitment Made for NUR EG-0612

REFERENCE:

(a) Phase Two Report to NUREG 0612, dated March 1,1982 Gentlemere in Reference (a), we submitted our phase two report providing information requested by NUREG-0612,

" hot" spent fuel as fuel which was removed from the reactor during a refueling (fuel shuffle) and for 45 days after the completion of that shuffle, was considered to be "ho t."

Additionally, we stated that mechanical stops would be installed to prohibit the spent fuel cask handling crane trolley from approaching closer than 25 feet to

" hot" spent fuel.

Our definition of " hot" spent fuel was conservative based on Figure 2.1 - 1 in NUREG-0612. It limited offsite dose to less than one-fourth of the 10 CFR 100 limits.

The definition of " hot" spent fuel should be ht.,ed on time after the shutdown of the plant and not time after removal of the last assembly from the reactor vessel. We feel the use of this definition will lircit the offsite dose to less than one-fourth of the 10 CFR 100 ilmits.

We intend to clarify our commitment to the NUREG more extensively in the future, but as an immediate action, are clarifying our definition of " hot" spent fuel to mean fuel which has resided in the core of a plant, shutdown within the last 45 days. We would appreciate notification of your concurrence with this clarification so that work which is being delayed due to the existing definition may proceed.
