Enclosed is IE Bulletin No. 79-06-A, which requires action by you with regard to your Westinghouse designed pressurized water reactor facility(ies) with an operating license.

Based on our current understanding of the Three Mile Island accident sequence, and discussion with the designer of your pressurized water reactor, we have reason to believe that pressurizer level indication in your facility may not provide reliable information regarding level in the reactor coolant system under certain transient or accident conditions. You should immediately instruct your operating personnel accordingly. In addition you should consider this possibility in responding to the enclosed bulletin.

Should you have any questions regarding this Bulletin or the actions required by you, please contact this office.

Sincerely,

<VJ mes P. 'Reilly Director
