TECHNICAL SPECIFICATIONS

!* 3.3 Reactor Primarv Pool Water Applicability. This specification applies to the primary water of the reactor pooi.

Objective. The objective is to ensure that there is an adequate amount of water in the reactor pool for fuel cooling and shielding purposes, that the bulk temperature of the reactor pool water remains sufficiently low to guarantee demineralizer resin integrity, and that pooi chemistry will limit corrosion.

Specifications.

a. The pooi water level shall be greater than 5 meters above the upper core plate. The pool water level shall initiate an alarm signal if the pool level falls 10 cm below normal. The alarm indication shall be visible in the control room and outside the reactor facility.

b. The bulk pool water temperature shall be less than 40°C. The pool water temperature shall initiate an alarm if the pool temperature exceeds 40°C.

c. The conductivity of the pool water shall be less than 5.0 microsiemens/cm averaged over 1 month.

d. The pH of the pool water shall be between 5.0 and 7.5 averaged over 1 month.

e. The radioactivity of the pool water shall be less than the limits in 10 CFR 20 Appendix B, Table 3 for radioisotopes with half-lives greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

Pool Water Level: The, minimum height of 5 meters of .water above the upper core plate guarantees that there is sufficient water for effective cooling of the fuel and that the radiation levels at the top of the reactor are within acceptable levels. The pooi level is limited to a decrease of no more than 10 cm below normal to allow early detection of pool leakage. (RAI Response, May 20, 2011)

Pool Water Temperature: The bulk water temperature limit is necessary, according to the resin manufacturer, to ensure that the resin does not break down. The temperature limit also ensures the core inlet temperature is acceptable for the accident analysis. (RAI Response, December 12, 2011)

Pool Water Conductivity and pH: Experience at many research reactor facilities has shown that maintaining the conductivity and pH within the specified limit provides acceptable control of corrosion (NUREG-1537 Appendix 14, Section 3.3.(9)).

Pool Water Radioactivity: Pool activity is limited to ensure dose rates are maintained below 10 CFR 20 limits.
