unsu capou s. win N e sota es4oi February 6, 1981 Director of Nuclear Reactor Regulation U S Nuclear Regulatory Commission Washington, DC 20555 PRAIRIE ISLAND NUCLEAR GENERATING PLANT Docket Nos. 50-282 License Nos. DPR-42 50-306 60 Emergency Response Plan In response to the new Part 50 regulations on Emergency Planning, on August 15, 1980 we submitted copies of an upgraded plan. Your review of this plan resulted in the comments forwarded with your letter of November 14, 1980.
As outlined in our November 26, 1980 letter we have proceeded to develop revisions to the plan t,esponsive to your comments.
With this letter we are furnishing 10 copies of the appropriate revised plan that will be implemented by April 1, 1981. This revised plan is identified as "Rev 0" to distinguish it f rem the prior vers ion. As indicated in our January 30, 1981 letter relating to NUREG-0737 items, this revised plan includes a description of a meteorological system intended to meet the first phase requirements of Appendix 2 to NUREG-0654 Rev 1.
Regarding the alert and notification requirements of Appendix 3 to NUREG-0654 Rev 1, we are providing the attached status report.
Although the warning system evaluation program is proceeding on schedule, it is certain, at th is t ime, that the fully expanded system needed to meet the requirements of Appendix 3 cannot be functioning by the prescribed date of July 1, 1981. Following completion of the evaluation program we will be in a position to establish a realistic date for having the alert and notification capability.
The attachment includes a brief description of the existing system capability which constitutes an interim solution to the regulatory requirements.
Copies of the required emergency response plans of the State and local governmental entities were furnished with our letter of December 18, 1980.
These are vital companion documents to our emergency response plans and we have taken steps to insure that both sets of plans are available to the personnel involved in emergency response.

s At tachment to February 6,1981 Letter to NRR Alert & Notification Status Report Within the Plume Exposure EPX there exists provisions for alerting and providing notification to the public. The States and local governments with responsibility for activating alert and notification systems have a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day capability. The present system capability as outlined in the state plan includes:
e Within 15 minutes
- plant notifies state (s)
- state (s) notify local government
- state (s) notify EBS & NOAA
- EBS & NOAA broadcasting Within 30 minutes local government will:
e
- Notify 100% of the population with 3 miles of the plant
- Notify 75% of bhe population within 3-10 miles of the plant To determine the present level of coverage, relative to design objectives of NOREG-0654, Northern States Power Company has retained WYLE Laboratories i
to survey the plume exposure EPZ.
in addition to assessing the present coverage, WYLE recommendations will provide the basis for farther addition to the alert and notification system.
Three basic warning systems are currently being evaluated rf Wyle Laboratories as a basis for the design recommendations for the 10-sile EPZ surrounding Prairie Island and Monticello Nuclear Generating Stations; these are:
Outdoor Warning Siren - pneumatic / electrical acoustic source designed o
to produce sufficient sound power for providing an adequate warning signal to distances as great as a mile away from the source.
Sirens will be recommended for alerting population centers, recreational areas, and major industrial sites, e Indoer Tone Alert Receiver - radio receivers designed to provide an alerting signal as well as receive and broadcast emergency instructions.
Tone alert receivers would be located in all key commercial and institutional structures within the EPZ acd in every structure within 10 miles of the plant but outside of siren covered areas.
e Mobile Siren System - automobile, boat, or aircraft-based mobile systems employing sirens / loudspeakers to warn people in localized areas, transient populations in remote areas, handicapped people, etc.
Mobile systems would be predominantly backup and would be i
used on an as-available basis,
