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: 1. 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 2. 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 3. 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. ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** complete - **CPV codes:** 71356000 - **Delivery regions:** UK - **Delivery countries in notice:** GB ## Awards & Winning Suppliers (1) - **Award:** 1 (active) - Supplier(s): **United Kingdom National Nuclear Laboratory Limited (UKNNL)** - Supplier identifiers: `GB-FTS-109827` - Value: £20,000 † (exc.
