.J REACTIVITY CONTROL SYSTEMS FLOW PATHS - OPERATING LIMITING CONDITION FOR OPERATION 3.1.2.2.1 Two flow paths from the boric acid storage tanks via either a boric acid pump or gravity feed connection, and a charging pump to the Reactor Coolant System and one associated heat tracing circuit shall be OPERABLE.
APPLICABILITY: Modes 1, 2 and 3*
ACTION:
With only one of the above required boron injection flow paths to the Reactor Coolant System OPERABLE, restore at least two boron injection flow paths to the Xeactor Coolant System to OPERABLE status within 48 i

3.1.2.2.2 At least two of the following three boron injection flow paths and one associated heat tracing circuit shall be OPERABLE:
Two flow paths from the boric acid storage tanks via either a a.

',, 4 SURVEILLAtiCE REQUIREMENTS 4.1.2.2 The two required flow paths shall be demonstrated OPERABLE:
a.
At least once per 7 days by:
1.
Exercising all testable power operated valves in each flow path through at least one complete cycle, 2.
Verifying that the temperature of the heat traced portion of the flow path from the concentrated boric acid tanks is above the temperature limit line shown on Figure 3.1-1, b.
At least once per 31 days by verifying the correct position of all manually operated valves in the boron injection flow path locked, sealed or otherwise secured in position and not c.
At least once per 18 months, during shutdown, by exercising all power operated valves in each flow path through at least one complete cycle.
