Going Nuclear, Part 3: Southeast Asia, Great Powers and Small Reactors

Southeast Asia’s nuclear conversation is not simply about generating electricity. In “Going Nuclear, Part 3”, the larger question is whether countries in the region can weigh small-reactor ambitions while navigating the influence, interests and expectations of major powers.

Published by the Hinrich Foundation as a white paper, the paper places an unresolved question at the center of the debate: what does a workable nuclear path look like when technology choices also carry strategic consequences?

Going Nuclear, Part 3 puts Southeast Asia’s choices in context

The paper’s framing matters because it treats nuclear policy as more than a technical procurement decision. A decision involving nuclear energy can also shape a country’s external relationships, the partners it relies on and the degree of control it retains over a long-term national project.

• Region in focus: Southeast Asia
• Core policy setting: competition and engagement among great powers
• Technology under discussion: small reactors
• Central tension: an open question about the region’s nuclear future

That combination makes this a useful lens for readers who want to look beyond the usual yes-or-no argument about nuclear power. The more difficult issue is how governments evaluate choices whose political and strategic effects may extend well beyond the reactor itself.

Great-power competition changes the nuclear calculation

For Southeast Asian governments, engaging with major powers can create opportunities, but it can also make every partnership more consequential. The paper’s title explicitly connects the region’s nuclear discussion to great powers, signaling that geopolitical positioning belongs alongside engineering, finance and domestic policy.

Rather than assuming that one outside relationship defines the answer, policymakers must consider the trade-offs attached to different forms of cooperation.

• Technology relationships: who provides or supports a reactor option can matter strategically.
• Policy autonomy: governments may need to protect room to make independent decisions over time.
• Long-term commitments: nuclear choices can create relationships that last far beyond an initial agreement.
• Regional balance: national decisions may be interpreted through the wider dynamics of Southeast Asia.

This is why the question cannot be reduced to selecting the most attractive proposal on paper. A responsible assessment also asks what a partnership requires, what it enables and what it may constrain.

Small reactors are part of the Southeast Asia nuclear debate

Small reactors feature prominently in the paper’s framing, placing them within a policy discussion rather than presenting them as a standalone answer. Their relevance lies in the fact that they invite governments to consider a different scale of nuclear option while still confronting the same strategic questions around partners and national priorities.

• Scale is not the only issue: a smaller reactor concept does not remove the need for careful state decision-making.
• Partner selection remains important: technology choices are tied to relationships with external actors.
• Governance still matters: policymakers need a clear process for evaluating complex, long-lived commitments.
• Public clarity is essential: discussion should distinguish between a technology option and a complete national strategy.

The useful takeaway is restraint. Small reactors may broaden the conversation, but they do not settle the political, institutional or geopolitical questions that the conversation raises.

The open question is the paper’s most important feature

The phrase “an open question” is not a gap to be rushed past. It is an invitation to examine uncertainty honestly: what Southeast Asian countries want from nuclear energy, how they assess competing external interests and what conditions they would need before moving forward.

Keeping the question open also avoids treating Southeast Asia as a single actor with a single set of priorities. The region’s nuclear debate is best understood as a series of national choices made within a shared and highly connected strategic environment.

• What is being decided: not only whether to pursue a technology, but how to structure the decision.
• Who is involved: domestic institutions, external partners and regional stakeholders all shape the context.
• What requires scrutiny: the strategic implications of long-term nuclear cooperation.
• What remains unresolved: the route each country may choose and the conditions it will place on that route.

Why this white paper matters

Written by Alvin Chew and dated June 23, 2026, the Hinrich Foundation white paper offers a timely frame for a debate that is often discussed in overly simple terms. Its value is in bringing together three subjects that are too often separated: Southeast Asia, small reactors and major-power politics.

Readers should come away with a more demanding standard for evaluating nuclear proposals. The relevant question is not just whether an option appears promising, but whether it fits a country’s wider strategic interests and decision-making capacity.

Key takeaways

• “Going Nuclear, Part 3” examines Southeast Asia through the linked lenses of nuclear policy and great-power dynamics.
• Small reactors are part of the discussion, not a substitute for broader policy analysis.
• External partnerships can influence the strategic meaning of a nuclear choice.
• The unresolved question is how countries in the region can make choices that preserve their interests over the long term.

What comes next for Southeast Asia’s nuclear debate

The next stage should be defined by sharper questions, not premature certainty. As the conversation develops, the strongest policy approach will be one that treats technology, national interest and regional diplomacy as connected parts of the same decision.

That is the enduring value of the paper’s framing: it encourages readers to see Southeast Asia’s nuclear future not as a race toward a single answer, but as a strategic choice that demands patience, clarity and careful judgment.
