REQUEST FOR ADDITIONAL INFORMATION UNIVERSITY OF FLORIDA TRAINING REACTOR DOCKET NO. 50-83 By letter dated April 7, 2008, you provided a response to the NRCs request for additional information (RAI) dated April 6, 2005. The NRC staff has reviewed your response and has determined that further information is required. The following additional information is requested related to your response to question 5-2 related to Section 5.3, Secondary Coolant System.
- 1. Your letter dated April 7, 2008, states that the normal operating pressure for the secondary side is not monitored, but that secondary flow rate is about 4 times higher than the primary flow rate so the dynamic pressure of the secondary system is expected to be higher than the primary system pressure. Therefore, if a significant leak is developed on the primary/secondary boundary, the resistivity of the primary water is expected to change, which is constantly monitored and controlled. The technical specifications (TSs) limits on primary flow rate are greater than 36 gpm or 41 gpm depending on fuel coolant channel spacing tolerance, and the TSs limits on secondary flow rate are greater than 60 gpm when using a well system and 8 gpm when using city water.
Is the assumption that a significant leak would be detected in the primary water resistivity valid if the reactor is operating at the TS limit of 36 gpm or 41 gpm primary flow rate (or normal primary flow rate if it is in excess of the allowed TS limit) and 60 gpm or 8 gpm secondary flow rate? In your response, address how the primary and secondary pressures are affected by the flow characteristics in the heat exchanger.
- 2. Your letter dated April 7, 2008, states that with conservative assumptions on sodium in the primary coolant system, irradiation time, neutron flux level, cross section, primary-to-secondary leakage and secondary diluting flow, the following values are determined for a 1 liter/hr undetected leak rate continuing for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> with 1 ppm sodium assumed in the primary coolant system. Activation for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> yields ~54 mCi Na-24 in the primary coolant tank at a concentration of ~0.0895 Ci/mi before dilution by the secondary flow. For a 1 liter/hour leak rate undetected for an hour, the concentration assuming 140 gpm well water flow (minimum based on well water flow without flow warning light), the concentration becomes ~2.8E-06 Ci/ml. Public release is allowed at 5E-3 Ci/ml so we conclude that this unlikely event would not be a problem in this regard.
- a. What is the basis for the assumptions of 1 ppm sodium in the primary coolant, activation for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />, and 1 liter/hour leak rate for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />?
- b. How is the public release limit (5E-3 Ci/ml) derived? Appendix B to 10 CFR Part 20, Table 2, Column 2, lists an average yearly concentration release limit of 5E-5 Ci/ml for water effluents, and Table 3 list a monthly average concentration release limit to sewers as 5E-4 Ci/ml.
ENCLOSURE
- c. As discussed previously, the TS limit on secondary flow rate is 60 gpm when using well water and 8 gpm using city water. Therefore, provide an estimated effluent concentration assuming the allowed TS limits for secondary flow.
- d. What is the basis for your conclusion that a primary to secondary leak is unlikely?
