Three Mile Island Nuclear Station, Unit 1 (TMI-1)
Operating License No. DPR-50 Docket No. 50-289 Emergency Plan Implementation On February 27, 1981, you and your staff met with Company representatives to discuss the status of the TMI-l Emergency Plan. At that meeting we delivered to you a map designating where we currently plan to locate sirens within the plume exposure pathway in order to demonstrate compliance with the guidance on early warning and notification systems included in NUREG-0654, Appendix 3.
My staff also explained to you the basis on which the siren locations were chosen. An implementation schedule was discussed; a ccpy of that schedule is attached to this letter. We plan to submit to you my mid-April, 1981, a written report describing the siren system, explaining the methodology used in locating the sirens, and demonstrating, by theoretical calculation, compliance with the applicable design criteria.
The TMI-l Emergency Plan will be modified following installation and initial testing of the system to contain relevant infor=ation on the system, including the means to be used to activate the system.
At this meeting the public education and infomation program was also discussed.
Brochures containing such information were given to the Staff for their review.
Information describing an approximate schedule and the means to be used by the ' Company for <';stributing this material will be provided to you in March, 1981. Appendix B of the Emergency Plan will be modified accordingly.
Another item of discussion at the meeting related to the use of thyroid blocking drugs for onsite workers. TMI already has a stockpile of KI on site. One of our consultants, RMC, has developed guidance on the use of this drug, and a procedure incorporating this guidance will be developed.
Sincerely, OYf 5
