Gen3CSP sCO2 Loop Scope of Supply (V0.0.3)

Alvarez, Francisco; Carlson, Matthew D.

The Generation 3 Concentrating Solar Power (Gen3CSP) supercritical carbon dioxide (sCO₂) coolant loop, typically referred to here as the `sCO₂loop,' is designed to continuously remove heat from a primary heat exchanger (PHX) subsystem through a flow of sCO₂ as a substitute for a sCO₂ Brayton power cycle as shown in Figure 1-1. This system is designed to function as a pumped coolant loop operating at a high baseline pressure with a high degree of flexibility, stability, and autonomy to simplify operation of a Gen3CSP Topic 1 team Phase 3 pilot plant. The complete system includes a dedicated inventory management module to fill the main flow loop with CO2 and recovery CO2 during heating and venting operations to minimize the delivery of CO2 to the site.
