Description

Follow on from some work partially done in #3386

Namespace changes

Functions

Variables

• pcoreradpv -> pden_plasma_core_rad_mw
• pedgeradpv -> pden_plasma_outer_rad_mw
• maxradwallload -> pflux_fw_rad_max
• coreradius -> radius_plasma_core_norm
• palpfwmw -> p_fw_alpha_mw
• wallmw -> pflux_fw_neutron_mw

---

✨ New additions

• p_plasma_sync_mw: Represents the total synchrotron power from the plasma.

🐛 Bugs

There was never a variable representing the total synchrotron power from the plasma, instead it was always outputted as (pden_plasma_sync_mw*vol). This would cause parsing issues due to *. A new variable p_plasma_sync_mw has been created in physics_variables.f90 to fix this.
