Feasibility Study of Reactor-Based-Deep-Burn Concepts

A systematic assessment of the General Atomics (GA) proposed Deep-Burn concept based on the Modular Helium-Cooled Reactor design (DB-MHR) has been performed. Preliminary benchmarking of deterministic physics codes was doneby comparing code results to those from MONTEBURNS (MCNP-ORIGEN) calculations. Detailed fuel cycle analyses wereperformed in order to provide an independent evaluation of the physics and transmutation performance of the one-pass andtwo-pass concepts. Key performance parameters such as transuranic consumption, reactor performance, and spent fuelcharacteristics were analyzed. This effort has been undertaken in close collaborations with the General Atomics design teamand Brookhaven National Laboratory evaluation team. The study was performed primarily for a 600 MWt reference DB-MHRdesign having a power density of 4.7 MW/m(sup 3). Based on parametric and sensitivity study, it was determined that themaximum burnup (TRU consumption) can be obtained using optimum values of 200 (micro)m and 20% for the fuel kerneldiameter and fuel packing fraction, respectively. These values were retained for most of the one-pass and two-pass designcalculations; variation to the packing fraction was necessary for the second stage of the two-pass concept. Using a four-batchfuel management scheme for the one-pass DB-MHR core, it was possible to obtain a TRU consumption of 58% and a cyclelength of 286 EFPD.NTIS
