FMCRD Scram Times
Dear Chet:
Enclosed are the FMCRD scram times that George Thomas (NRC) and Dick Ose (GE) discussed on April 26,1994. These scram times are for the nominal charge pressure of 2134 psig and for the minimum allowable charge pressure of 1850 psig. This is the same information that was provided at an earlier date.
Please provide a copy of this transmittal to George Thomas.
Sincerely, L
