IEEFA Australia responds to nuclear energy proposal

Sydney, Australia (SPX) Jun 09, 2024

In response to Opposition Leader Peter Dutton's plan to achieve Net Zero, Amandine Denis Ryan, CEO of IEEFA Australia, commented on the proposed nuclear policy, referencing IEEFA's research. David Schlissel of IEEFA, with over 50 years of experience in nuclear power research, co-authored a report with Dennis Wamstead. Their findings indicate that Small Modular Reactors (SMRs) would take significantly longer to build than proposed. According to the report, nuclear projects worldwide have faced budget overruns due to delays and various unknown factors.

IEEFA, an independent think tank, is committed to researching and reporting on the most financially viable methods to achieve Net Zero, aiming to avoid burdening taxpayers with future costs. Below are some quotes from Amandine Denis Ryan:

"The research by IEEFA's nuclear experts calls into question whether nuclear makes financial sense for Australia, for a multitude of reasons - timing, cost, compatibility with renewables and liability issues to cite just a few."

"Our research shows that nuclear reactors - both small modular reactors (SMRs) and gigawatt-scale reactors - in comparable countries have consistently taken longer and have been more expensive to build than expected. With over 50 years experience in this space, our analysts have researched nuclear projects around the world. For a country like Australia, starting from scratch, we expect that nuclear power reactors would not reach commercial operation before the 2040s, would come at a high cost, and require substantial government support."

"Nuclear plants in Australia cannot be built in time to replace Australia's fleet of coal power stations, more than 90% of which are expected to retire in the next 10 years. Our research aligns with CSIRO and the regulators' assessment that it would take at least 15 years to first production.

"The few existing SMRs in operation took over 12 years to build, despite original construction schedules of three to four years. Large reactors have a history of long delays, with most recent projects taking nine years or more from the first concrete pour, which in turn can only take place after years of planning, contracting and pre-construction works. This is in addition to the time required to develop the regulatory regime."

"Nuclear plants are notorious for cost overruns. Our analysts found that SMRs in operation or under construction cost three to seven times more than originally planned. Proposed SMRs in the US have also already seen cost estimates blow out by between two and four times in recent years. Large-scale reactors often face cost overruns as well. The Flamanville EPR in France is an extreme example of this, with costs having more than quadrupled despite France's deep expertise on nuclear."

"Nuclear plants are not a good complement for renewable generation. They can be flexible within a range, however the economics rely upon being operated in 'baseload' mode. In the 2040s, when the first nuclear plants could begin operating, the Australian Energy Market Operator expects that over 90% of generation will be supplied by variable renewables (wind and solar), and that the average annual utilisation factor of gas generation assets will be between 3% and 15% to complement them. Our analysts estimate that at a utilisation factor below 25%, the cost for electricity supplied by an American SMR would increase to more than AUD 600/MWh, if it was even possible to achieve such a low utilisation operationally."

"One of the major risks for investors in nuclear assets is the size and allocation of liability in case of an accident, with international conventions stating that operators of nuclear installations are liable should an incident occur. Such liabilities are very challenging for a company to carry by itself.

"In the United States, this issue was addressed with the Price-Anderson Nuclear Industries Indemnity Act (1957) by creating a shared insurance pool, now totalling AUD 22.5 billion across the almost 100 reactors covered. The US Government is exposed to costs beyond the insurance pool. Full costs associated with the 2011 Fukushima disaster could be as high as AUD 770 billion. It is unclear how Australia would be able to manage these liabilities without very material government underwriting of risk."

High Assay Low-Enriched Uranium Fuel Poses Major Proliferation Threat
Los Angeles CA (SPX) Jun 07, 2024
An analysis published in the journal Science found that the high assay low-enriched uranium (HALEU) produced with federal subsidies for small nuclear power reactors can be used to make nuclear weapons, presenting greater terrorism and nuclear proliferation threats than acknowledged by the federal government and industry. "Were HALEU to become a standard reactor fuel without appropriate restrictions determined by an interagency security review, other countries would be able to obtain, produce, and ... read more
