NuScale Power Just Solved a Major Engineering Hurdle: Is the Stock a Buy?

NuScale Power and MilleniTEK fabricated first-of-a-kind boron-oxide pellets for the passive emergency core cooling system in NuScale's 77 MWe small modular reactor, advancing a critical safety component toward commercial manufacturing. The milestone may reduce construction-stage supply bottlenecks, supported by master service agreements with more than 60 specialized suppliers. However, NuScale's first planned deployment, the up-to-six-module RoPower Doicești project in Romania, is not expected online until 2033, while a potential TVA agreement for up to 6 GW remains nonbinding and uncertain.

Analysis

The pellet fabrication is a technology-readiness datapoint, not a bankable revenue catalyst. It modestly reduces one component-level execution risk, but it does not address the binding constraints on SMR equity value: customer financing, fixed-price EPC risk, site licensing, fuel availability, and credible construction-cost estimates. SMR should therefore be valued as a long-duration development option; incremental engineering milestones can sustain retail momentum but should not justify a material change in probability-weighted 2030s cash flows.

The more relevant 1-3 month catalyst is whether a TVA/ENTRA1 arrangement converts from collaboration into a financed, enforceable order with defined commercial terms. A headline capacity target without take-or-pay commitments, government credit support, or an identified owner-of-last-resort is unlikely to de-risk SMR following its prior project cancellation. Conversely, a binding framework could rerate the broader advanced-nuclear complex, benefiting BWXT and LEU more directly because they have nearer-term manufacturing/fuel-cycle exposure rather than relying solely on first-of-a-kind project completion.

Contrarian view: the market may over-credit NRC design approval as a moat while underweighting the possibility that data-center demand favors faster, more financeable alternatives—gas generation plus CCS, grid-scale storage, or large-reactor life extensions—before SMRs can be delivered. Any sustained SMR rally absent contract economics creates a favorable volatility-selling or relative-value setup rather than a reason to chase the common stock. The thesis is falsified by a funded multi-module contract with credible EPC partners, disclosed target capex/MWh economics, and customer-backed financing.

Key Decisions for Investors

• Do not initiate a core SMR long on this manufacturing milestone. Treat a sharp near-term rally as an opportunity to reduce exposure or establish a small tactical short only if no binding TVA/ENTRA1 economics emerge within 60-90 days; cover on disclosed financed orders rather than a nonbinding memorandum.
• Prefer a 6-18 month pair: long BWXT / short SMR in equal dollar beta-adjusted sizing. BWXT has tangible nuclear-component demand and existing revenue streams, while SMR remains most exposed to financing and first-project execution; reassess if SMR secures customer-funded EPC commitments.
• Add LEU to a watch list rather than buy solely on this news. A firm U.S. SMR deployment pipeline or government HALEU procurement expansion would be a cleaner, nearer-term fuel-cycle catalyst; absent that, demand timing remains too uncertain.
• For existing SMR holders, cap position size as venture-style exposure and use a year-end alert: upgrade only if management discloses contractually committed modules, customer credit support, project-level capital sources, and a cost estimate that is competitive with alternatives. A guidance delay or further cash-burn acceleration would invalidate a constructive view.
