{{#Wiki_filter:. 15.3.2 CHEMICAL AND VOLUME CONTROL SYSTEM Apolicability Applies to operational status of the chemical and volume control system. Obiective To define those conditions of the chemical and volume control system necessary to ) insure safe reactor operation. jipeci fication A. When fuel is in the reactor, there shall be at least one flow path to the core for boric acid injection. B. A reactor shall not be taken critical unless the following chemical and volume control system conditions are met: 1. A minimum of two charging pumps for that reactor shall be operable. 2.

(1) Required only during periods of power operation. (2) E determination will be started when the gross activity analysis of a filtered sample indicates ;t10yCi/cc and will be redetermined if the primary coolant gross radioactivity of a filtered sample increases by more than 10pCi/cc. (3) Drop test shall be conducted at rated reactor coolant flow. Rods shall be dropped under both cold and hot condition, but cold drop tests need not be timed. (4) Drop tests will be conducted in the hot condition for rods on which maintenance was performed. (5) As accessible without disassembly of rotor. (6) Not required during periods of refueling shutdown. (7) At least once per week during periods of refueling shutdown. (8) At least three times per week (with maximum time of 72 hours between samples) during periods of refueling shutdown. (9) Not required during periods of cold or refueling shutdown. (10) Sample to be taken after a minimum of 2 EFPD and 20 days power operation since the reactor was last suberitical for 48 hours or longer.
