Christopher Ashe contributed to the ukaea/PROCESS repository by engineering enhancements to plasma physics modeling, power calculations, and data visualization. He refactored core modules for naming consistency and maintainability, introduced new variables and methods for electric and thermal power modeling, and expanded support for detailed plasma pressure and impurity radiation profiles. Using Python, Fortran, and NumPy, Christopher improved performance by adopting efficient data structures and streamlined interpolation routines. His work included robust plotting capabilities with Matplotlib, improved documentation, and regression test stabilization. These changes deepened analytics fidelity, improved onboarding, and enabled more reliable, decision-ready outputs for scientific and engineering stakeholders.

27 Commits • 13 Features
Sep 1, 2025Month 2025-09 delivered refactors, plotting enhancements, and expanded physics capabilities in the PROCESS repository to boost readability, performance, and decision-ready metrics for impurity radiation and plasma pressure analyses. Key changes include a refactor of the impurity radiation module with variable renaming and initialization improvements, a performance upgrade to interpolation using numpy.interp, and plotting enhancements that expose core radiation reduction values and include ADAS radiation plots with documentation updates. The work also adds comprehensive plasma pressure profile support (electron, ion, fuel, total) with plotting, along with initialization of the total plasma pressure variable and a new plasma poloidal pressure contour plotting function. Documentation and notes on impurity modeling were updated to clarify assumptions and distribution considerations. Bug fixes addressed plot scaling and cleanup of obsolete variables to ensure reliable, consistent outputs. Overall, these changes improve code maintainability, analytics fidelity, and stakeholder visibility into radiation and pressure metrics.

Jun 1, 2025June 2025 — ukaea/PROCESS: Delivered substantial power-modeling enhancements, code hygiene improvements, plotting capabilities, and regression/test stabilization. This cycle focused on increasing accuracy of electric and thermal power calculations, improving maintainability through naming standardization, expanding visualization for stakeholders, and hardening tests to reduce regression risk. Delivered features include cryogenic load calculation in the Power class, expanded base load and per-unit-area power calculations, detailed power production calculations and reporting, addition of the f_p_plant_electric_recirc variable, and enhanced PROCESS plotting for central solenoid and coil structures. Major refactors standardized naming across modules (e.g., i_pf_energy_storage_source, pflux_plant_floor_electric, n_primary_heat_exchangers, eta_coolant_pump_electric, and related renames). Ramp-up outputs and burn-time logic were improved, and regression/test fixes and documentation updates were completed, including PROCESS PDF summary enhancements.
