Asdiscussed intheGL,licensees'were encouraged toproposeT/Schangesthatareconsistent withtheguidancegivenintheenclosures totheGL.Thelimitingconditions foroperation (LCOs)forthereactortripandengineered safetyfeaturesactuation system(ESFAS)instruments requirethatthesesystemsbeoperablewithresponsetimesasspecified intheT/Stables.Thesurveillance requirements specifythatthelicenseetestthesesystemsandverifythattheresponse ATTACHMENT 1TOAEP'NRC'1210 Page2timeofeachfunctioniswithinitslimits.Relocating thetablesofthereactortripandESFASinstrument responsetimelimitsfromtheT/SstotheUFSARwillnotalterthesesurveillance requirements.
