Spent fuel dry storage technology development: electrically heated drywell storage test (3kW operation)
An electrically heated drywell storage cell test has been in operation since March 1978 at the Engine-Maintenance, Assembly and Disassembly (E-MAD) facility on the Nevada Test Site in support of spent fuel dry storage technology development. This document presents the test data obtained at electric heater power output of 3.0 kW and compares the data with that for heater power outputs of 1.0 kW and 2.0 kW. The simulated drywell storage cell consists of a stainless steel canister (representative of the spent fuel canisters being tested at E-MAD) containing an electrical heater assembly, a concrete-filled shield plug to which the canister is attached, and a carbon steel liner that encloses the canister and shield plug. The entire test drywell is grouted into a hole drilled in the soil adjacent to E-MAD. Temperature instrumentation is provided on the exterior of the canister and liner, in the grout around the liner, and at six radial locations in the soil surrounding the drywell. Peak measured canister and liner temperatures are 785{sup 0}F and 747{sup 0}F, respectively. Previous testing showed peak measured canister and liner temperatures of 276{sup 0}F and 232{sup 0}F for 1.0 kW and 506{sup 0}F and 458{sup 0}F for 2.0 kW, respectively. A previously developed computer model was utilized to predict the thermal response of the test configuration. Computer predictions of the transient and steady-state temperatures of the drywell components and surrounding soil are presented and are compared with the test data.
