This assessment builds on previous PRPP evaluations commissioned by the Client for land‑based Generation IV reactor systems; specifically, PWR, HTGR, LFR, SFR and MSR designs and will consider how PRPP outcomes may differ when such reactor types are adapted for deployment onboard maritime vessels. The Study will include the following: - Technology and Design Review - Review of the global marine reactor development landscape to identify which previously assessed land‑based reactor types have credible or emerging marine‑based variants. - Identification and description of design changes associated with marine deployment, including but not limited to: Core size and configuration ### Core materials Fuel enrichment levels ### Fuel form ### Spent fuel volumes and properties ### Refuelling approach and operational cycles - PRPP Scenario Review - Re‑examination of the three threat scenarios used in the previous PRPP assessments (one proliferation scenario and two physical protection scenarios). - Qualitative commentary on how scenario assessments and scoring ‘would change’ because of: ### Siting reactors onboard maritime vessels Design modifications identified in the technology and design review - High‑Level Assessment Output - Development of a high‑level, qualitative description of how PRPP measure scores might be adjusted should an expert workshop be reconvened. - The Study will ‘not’ re‑score the original PRPP measures in detail, as the intent is to inform future expert assessment rather than replace it.
