Analytical study on tritium migration in NGNP and countermeasures to reduce tritium contamination

Ohashi, Hirofumi; Sherman, S. R.*

Nihon Genshiryoku Gakkai Wabun Rombunshi, 7(4), p.439 - 451, 2008/12

Tritium migration behavior in the Next Generation Nuclear Plant (NGNP) employing a high-temperature electrolysis (HTE) process to produce hydrogen is estimated by a numerical analysis. Estimated tritium concentrations in the hydrogen product and in a tertiary heat transport fluid in heat exchangers in the HTE process are higher than the limit in drinking water defined by the U.S. Environmental Protection Agency (EPA) and in effluent at the boundary of an unrestricted area defined by the U.S. Nuclear Regulatory Commission (NRC), respectively. The effect of some countermeasures to reduce tritium concentrations in the hydrogen product and the tertiary heat transport fluid are evaluated. Decreasing the tritium permeation rate between the secondary and tertiary heat transport circuits by the proposed water injection which produces HTO from HT according to an isotope exchange reaction in the heat transport fluids is an effective measure to decrease the tritium concentrations.
