Gentlemen:

SubJect: Nuclear Power Plant Staff Working Hours (Generic Letter No. 82-02)

The Commission has issued the attached policy statement on factors causing fatigue of operating personnel at nuclear reactors. It is being sent to you at this time for your information.

As part of the implementation of this policy statement, we are revising Regulatory Guide 1.33 and NUREG-0737 (Item I.A.1.3) to reflect the policy. In addition, we will be requesting all licensees to revise the administrative section of their technical specifications to require that administrative procedures follow the policy statement guidelines and that authorized deviations to the working hours guidelines be documented and available for NRC review. We will be contacting each licensee by separate letter once the Regulatory Guide and NUREG 0737 revisions have been completed (presently estimated for March 1982).
