> **RESTART.** Funded in FY2025 ($83.8M), zeroed in FY2026, $96.6M requested again in FY2027.

## Summary

This activity requests $96.6M in FY2027, 3.7% of project 250 — a restart, funded in FY2025 and zeroed in FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Pele will complete assembly and testing of the individual Reactor, Power Conversion, and Intermediate Heat Exchanger Modules, and deliver all to the Prime contractor facility for integrated Factory Acceptance Testing. At the completion of Factor Acceptance Testing, all elements will be prepared for shipment to INL. Pele will complete all site preparation at INL, to be ready to install modules and hardware upon arrival in early FY 2028

**FY2026 to FY2027 change.** The decrease supports phasing required for the Pele development cycle with remaining materials and components placed on contract in FY 2026, and final assembly planned for FY 2027.

## Before the request year

**FY2026 plans — current year.** Pele will complete detailed designs and drawings of all reactor and plant systems as well as the site at Idaho National Laboratory, and initiate procurements for all materials and components required to assemble the plant. Pele will complete the Preliminary Safety Analysis Report (PSAR) and submit to the safety authority, Department of Energy, for approval. The Pele core cartridge assembly will be completed and the reactor assembly will begin. Pele will complete development of the Control Module, and continue development of the Power Conversion and Intermediate Heat Exchanger Modules. Pele will complete production of the TRISO fuel compacts and transport the fuel to INL in preparation for reactor fueling in FY 2028. Pele will initiate production of the concrete pad and shield walls for the operational site at INL. The FY 2026 plan includes $41 million of discretionary (Congressional Add) and $209.1 million of mandatory (reconciliation) for a total of $250.100 million.

**FY2025 accomplishments.** Continue to purchase hardware and begin assembly of the four Pele modules. Fabricate and lay down concrete pad at the test site at Idaho National Labs (INL) while finalizing design of the rest of the concrete structure. Complete fuel for Pele core and ship to Idaho for preparation and storage. The SCO team will continue to work with the NRC in developing a regulatory process for future transport of microreactors. SCO will also support the development of requirements for a potential Service transition.
