This procedure contains instructions for the operation of the Dernincralizer Booster Pumps and the Chemistry Control Parnmeters for the Dernineralized Watcr Storage Tank (DST) and the I10NICS Water Treatment Plant Effluent.

2.0 APPLICABILITY This procedure applies to the operation of the Demineralizer Booster Pumps and the operation of the DST.

3.0 PRECAUTIONS AND LIMITATIONS 3.1 When handling the regeneration chemicals (acid and caustic soda) follow chemical safety rules per VEGP 30030-C.

3.2 The Plant Make-up Water Treatmen: Svs.tzrn has a maximum capacity of 400 gpnm with both trains operating or a capacity of 200 gpm with either train operating.

3.3 The Plant Make-up Water Trcatment System will not operate when the Make-up Well Water Storage Tank is below 5 feet.

3.4 Westronic Conductivity/Silica recorder ACRS-17575/AR-7520 controls the automatic on/off of demineralizer transfer pumps A- 141 8-P4-001, A-141 8-P4-002, and A- 141 8-P4-003. If the Westronic recorder is to be turned off, notify operations to switch demincralizer transfer pumps from the "auto" to "on" position.

Carter- Vogtle Electric Generating Plant 35510-C 57 Date Approved OPERATION OF TilE DE MINERALIZED WATER MAKEUP Page Nuirncr 11/14/2003 L T 3 of 5 4.0 SYSTEM DESCRIPTION The IONICS Water Treatment Plant wvill consist of two trains each capable of prod c~ing 200 GPM. Well water is supplied to the system from the well water storage tank by three Demineralizer Water Booster Pumps, each with a capacity of 220 GPM. The wvell water is filtered through multi-media filters prior to passing through a cartridge filter. After filtration the water is passed through a Reverse Osmosis (RO) system. Following the Reverse Osmosis system the water is passed through an Electo-deionization system (EI).

Following the EDI system the water passes through a series of Primary Polishing Mixed Bed Demineralizers. From the Primarv Mixed Beds the water is degassed in a Catalytic Hydrogen Oxygen Removal System (CORS). After the Oxygen removal the water is passed through a final set of'virgin resin Polishing Mixed Beds Prior to entering the DST.

IONICS personnel are responsible for the operation of the system and the production of high quality demineralized water required for the operation of the plant.

CONTINUOUS USE i 5.0 SYSTEM OPERATION NOTE

a. These valves and switches may be operated by Ionic personnel. These valves and hand switches will be included in ION'ICS operating procedure.

b. The use of these pumps and valves may be used during flushing and testing of permanent water treatrnent system.

5.5 When the Demineralizer Booster Pumps are no longer needed to provide water to the Ionics Water treatment facility:

(1) STOP Demin booster pump #1 - A-1408-P4-006 -by placing Hand Switch HS- 17407 in the OFF position.

(2) STOP D[emin booster pump #2 - A- I408-P4-007 - Switch by placing Hand HS- 17408 in the OFF position.

(3) STOP Demin booster pump #3 - A-1408-P4-008 -by placing Hand Switch HS-17409 in the OFF position.
