Push Button at Control Consolo (1) Flow orifice or heat exchanger AP (psi)in each operating heat exchanger leg corresponding to the flow value in the table.
(2) Not required below 50 KW operation if natural convection flange and pressure vessel cover are removed or in operation with the reactor suberitical by a margin of at least 0.015 AK.
(3) Trip pressure is that which corresponds to the pressurizer pressure indicated l.
in the table with normal primary coolant flow.
(4) Flow orifice AP (psi) corresponding to the flow value in the table.
(5) Core AP (psi) corresponding to the core flow value in the table.
Bases The specifications on high power, primary coolant flow, primary coolant pressure, a.
and reactor inlet temperature provide for the safety system settings outlined in specifications 2.2.a,2.2.b, and 2.2.c. In Mode I and II operation the core differential temperature is approximately 17 F d

SUBJECT:
Annlicability f
This specification shall apply to the reactor coolant systems.
Obiective It is the objective of this specification to assure proper coolant for safe operation.
Specification a.
The reactor coolant system shall consist of not less than a reactor pressure vessel, two primary system pumps, primary pressurizer, two primary heat exchangers, two pool system pumps, one 100% capacity or two 50% capacity.
pool system heat exchanger (s), and one pool system hold-up tank plus all associated piping and valves.
b.
The reactor coolant system shall have one secondary coolant system capable of-continuous discharge of heat generated at the operating power of the reactor, c.
The pumps and heat exchangers in the primary system shall constitute two parallel systems separately instrumented to permit safe operation at five megawatts on either system or ten megawatts with both systems operating
?
simultaneously.
