20555 July 6, 1979 IE Inforration Notice fio. 79-18 SKYLAB REEtlTRY Description of Circunstances:
The most recent dates for reentry of Skylab are July 10 to 14,1979, with July 12, as the most probable date.
Recognizing that a hit on a nuclear power olant would be highly unlikely by Skylab debris, the NRC believer it would be prudent for licensees to review their contingency plans ln case
';uch an event should actually occur.
The NRC is in communication with the Department of Energy (DOE), and will receive notificaticr. from them as soon as the reentry corridor can be established.
This noti', cation may occur within 1 to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> before reentry actually occurs.
If it is deternined that there are any licensed nuclear power plarts in the rcentry corridor, the plants will receive notification frcm their respective Regional Office via the dedicated phone line.
This Infornation Notice is provided as an early notification of a possibly significant ratter.
It is expected that recipients will review the informa-tion for possible applicability to their facilities, fio specific action or response is requested at this time.
If further NRC evaluations so indicate, an IE Circular or Bulletin will be issued to recommend or request specific licnesee actions.
If you have questions regarding the matter, please contact the Director of the appropriate NRC Regional Office.
No written response to this information notice is required.
