Dear Ed:
This -letter its.in response to ourl past conversations concerning the minimum gland water flow injection 'for your
'Byron Jackson service water pumps at, the Cooper.Nuclear
'Station.
'The ideal.operating range for 'the gland.ater injection
.is 3 to 4 gallons per minute at 25 ýPSI as dclearly delineated on our Outline Drawing,.2!-47471 Thisi* flow rate can be increased.to 6 gallons per minute without any adverse effect to hepu p operation.
BW/IP recommends
- an absolute minimum gland water flow injection :of 1.5 ý'gallons per minute..
The pump should be immediately tripped off-line If the injection flow'rate is at. this 15 gallons,,per miueor less.
rf you chould hae nyifrthcr q;,eiztins. in' regared 'tc 'the minimum gland wate-flow injection,, pleas, feel free.to contact me at your convenience.
