Title: Description of the West Valley demonstration project reference high-level waste form and canister

Technical Report ·
OSTI ID:6602722

This document provides information on the West Valley Demonstration Project (WVDP) reference HLW form and canister. The WVDP will solidify the liquid HLW remaining at the commercial nuclear fuel reprocessing plant at West Valley, New York. The reference waste form is borosilicate glass with a zeolite loading of 10 wt % and a waste sludge loading of 23 wt %. The glass formers that will be added to the waste during vitrification include Si, Al, B, and Na. Twenty-eight day and longer term leach tests show that the glass has adequate leach resistance. The room temperature density of the glass is 2.7 g/cm/sup 3/. Glass viscosity is 100 poise at 1049/sup 0/C. Upper and lower linear expansion coefficients are 99.02 x 10/sup -6///sup 0/C and 10.76 x 10/sup -6///sup 0/C, respectively. The glass transition temperature is about 470/sup 0/C. The reference canister will be fabricated from stainless steel 304. The length will be 300 cm, and the diameter will be 61 cm. The canister wall will be sheet with a minimum thickness of 0.34 cm. The bottom will be a flanged and reverse dished head with a thickness of 0.48 cm; the top will be an ASME flanged and dished head. The lifting flange will be fabricated from square bar. Each canister will be uniquely labeled on the shoulder and side of the canister. The maximum gamma dose rate of an average canistered waste form at time of production is expected to be 8500 R/h. Canistered waste standing in 25/sup 0/C air will have a centerline temperature of less than 45/sup 0/C. The weight of a 100% full glass filled canister will be 2480 kg. 9 refs., 8 figs., 23 tabs.
