Bad News for Nuclear: A Landmark Reactor Just Got Delayed — Barrons.com

What happened

GE Vernova Hitachi’s small nuclear reactor in Ontario is facing delays and cost overruns, according to Ontario Power Generation. It is expected to exceed its original cost target and probably will not begin operating by October 2030, its previously expected start date.

Confirmed

Global impact / market context

The delay and higher costs challenge the nuclear start-ups’ claim that new reactors can be built faster and more cheaply. If investors associate nuclear projects with long timelines and expensive power, they may become less willing to fund companies that still need to prove their designs.

Analyst inference

The Ontario project is the first small nuclear reactor to begin construction in North America, and its problems may influence views of the wider industry. The article says related companies’ shares can move with broad nuclear-sector sentiment, despite using different technology.

Confirmed

What to watch

1. Watch for updated construction timing and cost estimates from Ontario Power Generation; further slippage or overruns would reinforce concerns about the project’s schedule and budget. Analyst inference
2. The company attributed the problems to ongoing engineering, construction execution and supply-chain performance for this first-of-a-kind small modular reactor, or SMR. Confirmed
3. Watch whether investors continue to distinguish other reactor developers’ designs from this project, or instead treat its setbacks as evidence that the wider industry faces similar risks. Analyst inference
