<p class="MsoNormal">Recently I was challenged with allowing access into our U1 Containment Building to perform polar crane PM’s to gain time for mobilizing equipment into containment. The entry would be made around 50% power and then lowering power ~ 5 % every
hour until we trip the reactor at 20% power. I know Farley has in their procedure that entries into containment is not allowed while maneuvering power up or down at 3% or greater. I was wondering if any other utility had procedural restrictions on entering
containment at power and if so can you share that with me? I was able to present to the ALARA committee details I had from Salem and Diablo Canyon as well as the information I got for those who attended the Winter RP ALARA meeting. The committee voted no on
going in to do this activity. I need to put a bow on it so I am not challenged on this again. Thanks in advance!<o:p></o:p></p>
