Cold trap requirements for PHTS and IHTS sodium purification
Cold trap requirements for the Primary Heat Transfer System (PHTS) and the Intermediate Heat Transfer System (IHTS) are defined. The bases for these requirements are (1) maintaining concentrations of oxygen and hydrogen within given limits, (2) controlling the transport of tritium by coprecipitating it in cold traps together with hydrogen, and (3) providing the necessary volume capacity for collecting impurities. It is concluded that the 60 gpm, FFTF Type I, NaK cooled, cold trap will satisfy the PHTS requirements. For each of the IHTS loops a single, 60 gpm, cold trap is required; and an aircooled trap similar to the FFTF Type I design except for a 3-foot longer crystallizer section has been chosen for this service.

Leaching of radioactive nuclides from cement grouts. [Method for measuring rate of leaching of Cs-137 from cement grouts]
A method for measuring the rate of leaching of /sup 137/Cs from cement grouts was investigated as an alternate to the International Atomic Energy Agency (IAEA) method which requires long experimental times. The effects of curing time (10, 20, and 30 days) and the type of leachant (tap and saline water) on the amount of /sup 137/Cs leached were studied. Mathematical models for mass transport phenomena for both finite cylindrical geometry and a semi-infinite medium were developed to analyze the data. It was found that the models for diffusion of /sup 137/Cs with depletion of the species due to curing provided the best correlation of the data. The proposed method was found to give values of the mass transport coefficients within a factor of 2 to 10 of the IAEA test results. Diffusion coefficients were found to be in the range of 10/sup -9/ to 10/sup -11/ cm/sup 2//sec and depletion rate constants in the range of 10/sup -6/ to 10/sup -8/ sec/sup -1/.
