SUBJECT:
Scaling of the Alert and Notification System Requirements for the Lacrosse Boiling Water Reactor This memorandum is in response to your February 3,1987, memorandum and our subsequent meeting on February 19, 1987, concerning the Lacrosse Boiling Water Reactor alert and notification systs. The issue under review involves the Nuclear Regulatory Comtission (NRC) position relative to scaling ~ the design objectives for the Lacrosse alert and notification system. As a basis for your position you cited the power level of the reactor (less than 250 MWt);
the Final Dnergency Planning Rule Suppleentary Information.which concluded that reduced emergency plannirg zones could be established for small reactors based on the lower potential hazard posed by these facilities; and the footnote in NUREG-0654/ FEMA-REP-1, Revision 1, page 11, which suggests some site-specific scaling.
The IaCrosse alert and notification systs as now designed consists of a fixed siren, tone alert radios, and marine and aerial alerting components dispatched to notify the transient population. The permanent population can be alerted within 15 minutes throughout the entire EPZ based on the alerting mechanisms employed, namely, siren and tone alert radios. However, the single siren located at the plant site is designed to produce 60 dBC to less than two miles, and therefore that siren must be augmnted to provide an alert signal within 15 minutes for the transients outside the 60 dBC area. As stated previously, the design report identifies marine and aerial alerting components as the primary mans to notify transients outside the effective siren range.
It is FDIA's position that since the Dairyland Power Cooperative must couply with the 15 minute alert anc notification requirement within 3 miles for the transient population under the scaling provisions of your mmorandum, they should be able to extend this sama coverage out to 5 miles with minimal ad-ditional expenditure. Stated another way, whatever mthod is used to supple-ment the single siren, the difference in cost to notify transients frm 3 to 5 miles within 15 minutes versus 45 minutes would be relatively small, particularly when compared to the increased benefit to the public. For this reason, FEMA does not support scaling the alert and notification requirments for Lacrosse.
