.A (e) Closes only Rwcu system isolation valve (s) 1G33-F004 (SLCS Pump A) and 1G33-F001 (SLCS Pump B).

(f) Manual initiation isolates IE51-F064 and 1E51-F031 only and only following manual or automatic initiation of the RCIC system.

(g) Containment and Drywell Purge System inboard and outboard isolation valves each use a separate two out of two isolation logic.

(h) Requires RCIC system-steam supply pressure - low coincident with drywell pressure high to isolate valve 1E51-F077.

(i) For this signal, one trip system has two channels which close valves 1E51-F063.and-1E51-F076 while the other trip system has two channels which clcse valve 1E51-F064.

(j) Isolates both RHR and RCIC.

_( k) There is only one (1) RCIC n.anual initiation channel for valve group 9.

_s - -

This Trip Function no longer isolates the Main Steam Lines. The only isolation is of the mechanical vacuum pump lines (valves IN62-F130A and t B), using a single trip system consisting of two channels configured-a one-out-of-two logic.

LIMITING SAFETY SYSTEM SETTINGS BASES REACTOR PROTECTION SYSTEM INSTRUMENTATION SETPOINTS (Continued)

4. Reactor Vessel Water Level-Low The reactor vessel water level trip setpoint has beer used in transient analyses dealing with r.oolant inventory decrease. The scram setting was chosen far enough below the normal operating level to avoid spurious trips but high enough above the fuel to assure that there is adequate protection for the fuct and pressure limits.

5. Reactor Vessel Water Level-High A reactor scram from high reactor water level, approximately two feet above normal operating level, is intended to of fset the addition of reactivity ef fect associated with the introduction of a significant amount of relatively cold feedwater. An excess of feedwater entering the vessel would be. detected by the level increase in a timely manner. This scram feature is only effective when the reactor mode switch is in the Run position because at THERMAL POWER levels below 10% to 15% of RATED THERMAL POWER, the approximate range of power i

level for changing to the Run position, the safety margins are more than adequate without a reactor scram.

6. Main Steam Line Isolation Valve-Closure The main steam line isolation valve closure trip was provided to limit the amount of fission product release for certain postulated cusnts. The MSI 's a closed automatically from measured parameters such as high steam flow, 'i;h te;r 'ine ragioLm;Q31ow reactor water level, high steam tunnel temperature an ow steam line pressure. The MSIV's closure scram anticipates the pretsure-and flux transients which'could follow MSIV closure and-thereby protects reactor-vessel pressure and fuel thermal / hydraulic Safety Limits.
