By performing a flow balance test, during shutdown, following com-pletion of modifications to the ECCS subsystems that alter.the subsystem flow characteristics and verifying that:

1)

For centrifugal charging pump lines, with a single pump running: ,

a) The sum of the injection line flow rates, excluding the '

highest flow rate, is greater than or equal to 284 gps, and ,

b)

The total unit 575 sem pump 2 flow rate is less than or equal to 550 gpe(vnit

2) For Safety Inje(ction p) ump lines, with a single pump runn a) The sum of the injection line flow rates excluding the highest flow rate, is greater than or equ,al to 406 gpe, and b) The total pump flow rate is less than or equal to 660 gpe.

3) For RHR pump lines, with a single pump running, the sum of the i

injection line flow rates is greater than or equal to 3788 gpe.
