20555 July 6, 1979 IE Information Notice No. 79-18 SKYLAB REENTRY Description of Circumstances:
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 plant would be highly unlikely by Skylab debris, the NRC believes it would be prudent for licensees to review their contingency plans in case such an event should actually occur.
The NRC is in ccmmunication with the Department of "lergy (DOE), and will receive notification from them as soon as the reentry corridor can be established. This notification aay 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 determined that there are any licensed nuclear power plants in the reentry corridor, the plants will receive notification from their respective Regional Office via the dedicated phone line.
This Information Notice is provided as an early notification of a possibly significant ratter.
It is expected that recipients will review the informa-tion for possible anplicability to their facilities. No specific action or response is requested at this time.
If f urther 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 Offica.
