The Department of Energy's (DOE's) Office of Science (SC) and National Nuclear Security Administration (NNSA) are collaborating to acquire non-recurring engineering (NRE) and up to three exascale High Performance Computing (exascale HPC) systems. This collaboration, known as CORAL, involves Argonne National Laboratory (ANL), Lawrence Livermore National Laboratory (LLNL), and Oak Ridge National Laboratory (ORNL), which are collectively referred to as the Laboratories herein.

The exascale HPC systems described in the RFP are as follows:
* ORNL System delivered in 2021 and accepted in 2022 (ORNL system)
* LLNL System delivered in 2022 and accepted in 2023 (LLNL system)
* ANL Potential System delivered in 2022 and accepted in 2023 (ANL system)

The anticipated budget range for each system, including any associated NRE, is $400 million to $600 Million. The budget range for NRE alone is expected to be $75M to $150M. However, the actual NRE or system award amount may be more or less than the anticipated budget, depending on the Laboratories' perceived value of the proposal(s), resulting negotiations, and annual appropriated funding from Congress.
