' APPLICABILITY: OPEPliTIONAL CONDITION 1. N ' ACTION: a.- With an ATWS-RPT system instrumentation channel trip setpoint less conservative than the value shown in the Allowable Yalues column of. Table 3.3.4-2, declare the channel inoperable until the channel is. restored,to OPERABLE status with the channel trip setpoint adjusted consistent with the Trip Setpoint value, b. With the number of OPERABLE channels.one less than required by.the-I Pinimum OPERABLE Channels per Trip System requirement for one or imth trip systen.s, place the inoperable channel (s) in the tripped condition within 1 hour. c. With the number of OPERABLE channels two or more less than required by the Minimum OPERABLE Channels per Trip Systen, requirement for one trip system and: 1. If the inoperable channels consist of one reactor vessel water i level channel and cne reactor vessel pressure channel, place both inoperable channels in the tripped condition v' thin 1 hour, cr, if this acticr, will initiate a pump trip, declare the trip system inoperable. i 2. If the. inoperable channels include two reactor vessel water level channels or two reactor vessel pressure channels, declare the trip system inoperabic. d. With one trip system inoperable, restore the inoperable trip system to OPERABLE status within 72 hours or be in at-1 cast STARTUP within the next 6 hours. e.- With both trip systems inoperable, restore at least one trip system to OPERABLE status within 1 hour or be in at least STARTUP within the next 6 hours.
