MARVEL PDSA approval could serve as blueprint
MARVEL, the Microreactor Applications Research Validation and Evaluation project at Idaho National Laboratory, has had its preliminary documented safety analysis approved by the Department of Energy, marking a milestone in its development and serving as a potential outline for other microreactors in development.

The transport equation is considered in toroidal geometry using an expansion of Ψ(r, Ω) in unnormalized spherical harmonics, i.e., with being associated Legendre polynomials. The variable r is the position vector and Ω the direction with axial and azimuthal angles θ and , respectively. Equations for ψlm(r) and γlm(r) are obtained and a method of solution that has worked in other geometries is outlined.
