Report on the working group on 'Critique of Source Concepts'

The working group on ''Critique of Source Concepts'' examined and evaluated the proposed reactor- and accelerator-based steady state neutron source concepts with regard to: performance and fit to user needs, technical feasibility and R and D requirements, capital and operating costs, and unique safety or siting issues. A more or less conventional, D2O cooled and moderated research reactor, utilizing evolutionary advances in aluminum plate-fuel technology, can produce the desired 1016 n/cm2s flux levels in a large, accessible, user-friendly environment, with a relatively modest and low-risk R and D program, and at the lowest cost.
