Joskow: nuclear construction cost considerations
• Nuclear industry has a poor historical record on construction cost estimation, realization and time to build
• Few recent plants built and limited information on recent actual construction cost experience
• Nuclear industry has put forward very optimistic construction cost estimates but there is no experience to verify them
• Nobody has ever underestimated the construction cost of a nuclear power plant at the pre-construction stage

But cost overruns, quality assurance problems surely
now a thing of the pastAfter all, the same company that built most current
nuclear plants—and will probably also build most of the next generation—also built…
…the Big Dig.
(They’re also building the Yucca Mountain nuclear waste repository, so we can have confidence it will be leak-free for a few hundred thousand years or so.)

US construction wages are • 55% higher than Korea (OECD data)
• 25%-100%+ higher than China (Chemical plant construction manager)
• 11% below Japan (OECD data)
– costs generally $2,700-2,900/kW, but up to over $3,700/kW• 10% higher than Finland (OECD data)
– AREVA/OL3 = $2,300+/kW (nominal, but highly subsidized)– Competing OL3 bid from US A-E was >$2,500/kW (confidential
communication)
– Next AREVA reactor = $2,600 (Joskow)
• Current Northeast US nuclear reactors – 25-30% more expensive than other regions– Construction wages also 25-30% higher (Komanoff)

Accounting differences/uncertainties
• EDF/France allocates higher % of construction costs to administrative & general overheads – not to plant costs
• Asian plant accounting uncertain• US nuclear operating costs had 20-50% booked
to A&G; varied by plant– E.g., labor benefits (health, pensions), regulatory
expenses, PR, senior management time
![Page 15: Thank you for your kind attention](https://reader033.vdocuments.site/reader033/viewer/2022050810/56814bb9550346895db88a1e/html5/thumbnails/15.jpg)
Learning effects/price declines
• Poster child = France: 5.8% decline per doubling – One reactor type, one owner/builder, multiple reactors per site– Look back at Korean graph– Tradeoff design risk/competition
• Studies of nuclear industry learning find– Little to no correlation with overall industry size– Highest learning by company (utility construction managers,
not independent A-E), – Highest at multi-reactor sites– Some learning by reactor type
• Proposed next US generation = 3 reactors, ~10 companies, probably limited multi-reactor sites, mostly in region with limited complex construction experience

Challenges to EE/RE/DG – grow with increasing penetration
• EE – lower bills, but potentially higher prices• RE/DG – siting, siting, siting
– Near population centers– Highly visible– All local impacts vs. hidden fuel-cycle impacts
• Uncertainty over whether declining technology costs will overcome higher siting costs as use best sites
• Higher grid integration/storage costs as penetration increases
• EE/RE/DG – utility culture, profits

Why not EE/RE/DG + near-term nukes?
• Nuclear/CCS R&D already displacing EE/RE– Proposed zeroing out of hydro, geothermal– Reductions in several EE programs
• Nuclear raises near-term CO2 reduction costs– only cost-effective in high carbon price scenarios –
may not be politically viable• Forcing/subsidizing nuclear into mix
prematurely risks long-run public acceptance• Gen III+ is transitional technology that does not
meet safety, security, proliferation objectives
![Page 27: Thank you for your kind attention](https://reader033.vdocuments.site/reader033/viewer/2022050810/56814bb9550346895db88a1e/html5/thumbnails/27.jpg)
Long-term (20-30 year) prospects for new nuclear
plants brighten if…• External factors
– EE: Higher prices more important than lower bills– Renewables face insurmountable siting opposition– Grid integration/storage adds significant costs– EE/RE/DG does not muster adequate political support– Carbon capture and storage not feasible or very expensive– Need for higher CO2 reductions – high economic growth, low carbon
uptake, positive feedback loops, climate surprises– Low/zero carbon transportation requires electrification
1958 Ford Nucleon
• Nuclear industry factors– Existing nuclear plants retire in significant numbers– Nuclear industry addresses long-standing safety, security,
proliferation, waste, economic issues– Generation IV meets design objectives– Nuclear management/regulation avoids accidents– Nuclear licensing/regulation respects public concerns: becomes
inclusive rather than excluding

Existing nuclear plants are extremely profitable
• Consumers pay twice– First to original owners for “stranded
construction costs”– Second to new owners – single-price auction
pays everyone the price of the most expensive power plant in every hour

I. Fix the nuclear regulatory process:
risk management, generic safety issues
A. Risk Management• Plant owners should implement state-of-the-art methods to find and
fix errors of design, construction and operation at reactors and the NRC provide consistently effective oversight of those methods and their implementation.
• Risk-informed regulatory decision-making should be suspended until flaws in the plant risk studies they are based on are corrected.
B. Generic Safety Issues• Generic safety issues must be resolved in a timely manner and
accounted for as potential risk factors until resolved.

![Page 39: Thank you for your kind attention](https://reader033.vdocuments.site/reader033/viewer/2022050810/56814bb9550346895db88a1e/html5/thumbnails/39.jpg)
I. Fix the nuclear regulatory process: inspections
C. Inspections• Inspections of equipment outside the normal inspection scope must
be performed periodically to verify proper definition of the scope or to identify and correct definition errors before safety margins are compromised.
• Multiple inspection techniques of aging high-risk equipment must be used to provide better assurance that degradation will be detected and corrected.
• Reactors under construction must be subjected to extensive inspections to verify full compliance with safety regulations.

I. Fix the nuclear regulatory process: standards, safety
culture, security D. License extension standards• All of the differences between the regulatory requirements applicable to a
reactor and current regulatory requirements should be formally reviewed before any reactor is granted a 20-year license extension to verify that public health will be adequately protected.
E. Safety culture• The safety culture within the NRC must be monitored and restored to at
least the level the NRC, itself, deems minimally acceptable for operating nuclear plants.
F. Security• Adequate physical protection of nuclear plants against sabotage on both
sides of the Design Basis Threat level must be periodically demonstrated as well as the emergency response capability in event of a successful attack.
Slide 41

II. Avoid fundamentally unsound reactor designs
• Reactor and fuel designs must not make nuclear proliferation more likely. Reprocessing techniques must not involve plutonium in a form susceptible to theft or diversion unless commensurate security is provided.
• Reactor designs must incorporate physical protection features to lessen their vulnerability for radiological sabotage by internal and external sources.
• Demonstrate success with prototypes before building commercial reactors of novel designs.

IV. Resolve nuclear waste issues
• Onsite interim storage of spent fuel must reduce the risk from accidents and acts of malice.
• A high degree of consensus must be reached that the scientific and technical basis for repository site for high-level nuclear waste suitability is strong before it is licensed.
Slide 44
![Page 43: Thank you for your kind attention](https://reader033.vdocuments.site/reader033/viewer/2022050810/56814bb9550346895db88a1e/html5/thumbnails/43.jpg)
V. Limit financial support – create level playing field
• New reactors should be excluded from federal liability protection under the Price Anderson Act, as amended.
• New plants should not be disproportionately subsidized.
