ARDP Natrium Neutronic Methodology: Argonne Neutronic Assessment of ABR-1000

“…The negative worth reduces between Case 2 and Case 1 because as the sodium density is increased in the upper structures, the leakage from the reactor is reduced (thus a positive feedback). The combined effect from the sodium density change in Case 1 and 2 is still negative and is consistent with the positive sodium density coefficient reported in [2] and in Section 4.2.2. Moving to Case 3, There is a subtle point for the sodium inside the plenum above the fuel.…”

“…The total primary control system worth is $19.9 while the single stuck assembly worth is $17.4. These are ~50% less than that reported in Reference [2] which was traced to a difference in the absorber composition used in the current and the original [2] model. The OpenMC results for the primary and secondary control systems are presented in Figure 5-5 and Figure 5-6.…”

“…The traditional approach applied at ANL considers a uniform expansion of the homogeneously defined fuel assembly and movement with respect to grid plate changes, leading to increased volume fractions for the fuel, structure and coolant by 0.980296. In this approach, the densities of all solid materials present in the core are multiplied by a factor of 0.980296, corresponding to (1/1.01) 2 , or the inverse of the volumetric change in each assembly position. The density of sodium is not changed as the system is assumed to backfill the extra volume with flowing sodium.…”

Ducted Assembly Steady-State Heat Transfer Software (DASSH)

“…As a default, these are set to be calculated based on pin geometry parameters, as shown below. This assembly is the metallic driver fuel assembly designed for the ABR-1000 reactor [42]. The input takes on the default correlations and Nusselt number correlation parameters and omits the pressure drop calculation in the low-fidelity model region.…”

Requirements and Conceptual Design of Off-gas Systems for the Reprocessing of Metallic Fuels

“…The Advanced Fuel Cycle Facility was envisioned as a multipurpose R&D facility and was explicitly intended to include electrochemical reprocessing demonstration capabilities on the scale of 1 MTIHM/y. It was designed to process a fraction of the fuel discharged from the conceptual Advanced Burner Reactor (with a reference design of plutonium-based metallic fuel), with the remainder processed using aqueous-based technology (Cahalan et al 2007). The design effort was discontinued upon Global Nuclear Energy Partnership cancellation by the US DOE in 2009.…”
