WASHINGTON, D. C. 20555

May 9, 1983

TO ALL OPERATING REACTOR LICENSEES AND HOLDERS OF CONSTRUCTION PERMITS

Gentlemen:

SUBJECT: INTEGRATED SCHEDULING FOR IMPLEMENTATION OF PLANT MODIFICATIONS (GENERIC LETTER 83-20)

On May 3, 1983 the Commission issued Amendment No. 91 (Enclosure 1) to the Duane Arnold Energy Center (DAEC) operating license. This amendment incorporates a license condition which approves Iowa Electric Light and Power Company's "Plan for the Integrated Scheduling of Plant Modifications for the Duane Arnold Energy Center."

The Nuclear Regulatory Commission's statement of policy and planning guidance for 1983 endorses the concept of establishing implementation schedules for new and existing requirements which reflect the importance of the safety requirement to the public health and safety and the licensee's ability to complete the necessary engineering, evaluation and design. Enclosure 1 represents the first step towards development of an industry wide program to establish realistic schedules for implementation of safety improvements, both utility initiated and NRC-required, at operating reactors.

Enclosure 1 is provided for your information and possible use. Although this enclosure represents an approach which is acceptable at present to the NRC, other approaches may be acceptable and will be considered if you elect to adopt such a plan.

Please contact your Project Manager if you have any questions on this matter.

Sincerely,

Darrell G. Eisenhut, Director Division of Licensing Office of Nuclear Reactor Regulation

As Stated
