DESCRIPTION OF CONDITION:

Received Annunciator ANN -ANN - (A-4/E-6)i SW GLAND WTR SUPPLY SYS A TROUBLE, 'and ANN -ANN -(B-3/E-6), SW GLAND WTR SUPPLY SYS B TROUBLE, Bldg operator reported that the alarms were due to Low Pressure and they were both clear. The following parameters were-noted:

A/C Gland water pressure 18#

SWP A Gland water flow 5.4gpm SWP C Gland water flow- 7.8gpm B/D Gland water pressure 16.5#

SWP B Gland water flow 7.6gpm SWP D Gland water flow 6.3gpm No adjustments were made to the system, no other alarm were received.

REQUIREMENT NOT MET:

SW GLAND WATER LOW PRESSURE ALARMS

METHOD OF DISCOVERY:

02/08/.2004 23.:341:05 Rod L. Penfield (RLPENFI) Phone .402-825-5413 The following parameters were noted upon investigation:

A/C Gland water pressure 18#

SWP A Gland water flow 5.4gpm SWP C Gland water flow 7.8gpm BiD Gland water pressure 16.5#..

SWP B Gland Water flow -7.6gpm SWP D Gland Water flow 6.3gpm Sufficient :gland water to ýpumps was always maintained greater than 1.5 gpm. SW Operability not affected by the condition identified.

THIS IS THE ONLY ALARM THAT 'HAS BEEN RECEIVED ON THE SERIVE WATER GLAND WATER SYSTEM'. GLAND WATER FLOWS WERE MAINTAINED GREATER THAN 1.5 GPM AT ALL TIMES. MOST LIKELY THE CAUSE OF THIS 'ALARM WAS SYSTEM LOADING .DUE TO DEMANDS ON THE SCREEN' WASH AND SPARGER SYSTEMS. RECOMMEND SYSTEM ENGINEER TREND THIS CONDITIONI.
