# ABTR-250

The SCALE heterogeneous full core model of the Advanced Burner Test Reactor (ABTR)

with beginning of equilibrium cycle (BOEC) fuel was developed based on the

benchmark specifications for the ABTR developed by Argonne National Laboratory.

Using the initial BOEC full core model, a TRITON depletion calculation was performed

to obtain end of equilibrium cycle (EOEC) fuel composition.

The major references used to develop the provided models are the following:

- T. K. Kim (2020), "Benchmark Specification of Advanced Burner Test Reactor," 

  [ANL/NSE-20/65](https://publications.anl.gov/anlpubs/2021/01/164846.pdf), Argonne National Laboratory, Argonne, IL.

- Y. I. Chang, P. J. Finck, and C. Grandy (2006), "Advanced Burner Test Reactor Preconceptual Design Report," [ANL-ABR-1](https://www.ne.anl.gov/eda/ABTR_1cv2_ws.pdf), Argonne National Laboratory, Argonne, IL.

Results obtained using these models are summarized in ORNL TM report ORNL/TM-2022/2758.
