consumers Power company General Offices: 212 West Michigan Avenue, Jackson, Michigan April 2, 1981 Director, Nuclear Reactor Regulation Att Mr Dennis M Crutchfield, Chief Operating Reactors Branch No 5 US Nuclear Regulatory Commission Washington, DC 20555 DOCKET 50-255 - LICENSE DPR NUREG-0137 -
UPDATE -
PALISADES PLANT NRC letter dated October 31, 1980 incorporated into one document all TMI-related items approved for implementation by the Commission.
That total package, known as NUREG-0737, provided items to be addressed by licensees to improve safety at power reactors in view of the Three Mile Island incident.
Consumers Power Company's letter dated December 19, l980 provided our response to the items of NUREG-0737 for the Palisades Plant.
Since that submittal, it has become necessary to update our response as follows:
Item III.A.2 - Improving Licensee Emergency Preparedness.
Consumers Power Company has made arrangements to provide meteorological infor-mation by accessing National Weather Service (NWS) data through an automated computer system maintained by Weather Services International (WSI).
This in-formation will be used to determine the appropriate protective actions for the public in the event of any postulated accident.
Access to this system is accom-plished by use of a dial-up remote terminal at the plant site.
The reliability of the system is assured through the use of redundant computers and multiple telephone access ports.
Procedures have been established which allow the calcu-lation of Pasquill stability categories from the NWS data.
In addition to providing most recent and historic weather data, WSI will provide a display of the NWS recent forecast for the Palisades Plant area.
The forecast will be printed on the remote terminal upon request.
WSI forecasters also are available for providing meteorological data interpretation and evaluation on a 24-hour basis.
In the event this system becomes inoperable, plant emergency procedures provide an alternate source of meteorological information by calling the National Weather Service.
These information sources are available on a 24-hour basis and provide current meteorological information as well as long range detailed forecasts.

231 III.A.2 IMPROVING LICENSEE EMERGENCY PREPAREDNESS - LONG TERM NRG POSITION NRC POSITION Each nuclear facility shall upgrade its emergency plans to provide reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency.
Specific criteria to meet this requirement are delineated in NUREG-0654 (FEMA-REP-1), "Criteria for Preparation and Evalu-ation of Radiological Emergency Response Plans and Preparation in Support of Nuclear Power Plants."
LICENSEE ACTION Consumers Power Company will upgrade our emergency plans for the Palisades Plant to provide reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency.
Recommendations and schedules of NUREG-0737 are expected to be completed (C, I, D).
Require-ments under I(l), I(2) and I(3) have now been addressed.
Meteorological Data Meteorological data which is available for emergency use at the Palisades Plant includes 15-minute averages of wind speed, wind direction, temperatures at 10 and 60 me£ers and sigma-theta.
These data are available both in the control room and by remote interrogation from off-site locations.
Implementation procedures provide methods for rapid assessment of off-site dose based on concentration predictions which use X/Q values precalculated for Pasquill Categories A through G and presented on isopleth map overlays.
Capability for Glass A diffusion assessment modeling, backup data recovery and implementation of Class B diffusion modeling is expected to be provided in accordance with the milestones outlined in NUREG-0654.
As these future systems become available, remote interrogation capability will be expanded to assure ready access to off-site support facilities.
