i o ,: # IWhile in Mode 3, periodic testing of two steam supply valves determined that l l (TTT1 1 they would not cycle within the required time limit. The turbine driven I lo846Inuxiliarv feedwater pump (AFP) was declared inoperable nursuant to Technical f io,sil Specification 3.7.1.2 which is reportable per Technical Specification 6.9.1.13(b).

I a is i IFven thoueh there were no incidents reoutrine the use of the AFP's, in additiott io,7gIto both motor driven AFP's availability, the valves did eventually open makingg the turbine driven AFP available also. Thus, the health and safety of the public t o t e i Iwere unaf fected. I svgreis CAuBE cauBS CQh88 vaLvt cces caos sueccce couscaent:cos suecces susc=o.
