Discussion Overview

The discussion focuses on the costs associated with downtime in nuclear power plants, exploring factors that influence these costs and seeking reliable references for further research. The scope includes theoretical considerations and practical implications related to nuclear energy operations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant estimates the cost of downtime at around 1 million euros per day and seeks clarification on the key factors influencing this figure.
  • Another participant suggests that the cost of downtime primarily depends on the cost of replacement power, noting that factors such as purchasing power from neighboring utilities, fuel prices, and seasonal electricity demand can significantly affect costs.
  • A participant expresses a need for academic references or studies related to downtime costs for a university project.
  • Information about a CANDU reactor in Canada is mentioned, highlighting ongoing refurbishment issues and the associated costs of replacement power, which reportedly exceed a million dollars a day.
  • A participant provides a link to a Wikipedia page for further research, indicating that replacement power is only one aspect of the overall downtime costs.

Areas of Agreement / Disagreement

Participants generally agree on the significant costs associated with nuclear plant downtime, but multiple factors influencing these costs are discussed without a consensus on specific figures or comprehensive studies.

Contextual Notes

The discussion lacks specific academic references or detailed studies to substantiate claims about downtime costs. There are also unresolved questions regarding the broader implications of downtime costs beyond replacement power.

Who May Find This Useful

This discussion may be useful for students, researchers, and professionals interested in the economics of nuclear energy, power generation, and energy policy.

Hi all,

I'm looking for information on the costs of downtime within nuclear plants.

I have in mind that it's around 1million euros per day but I'd like to have a clear overview of the key factors that may influenced this number. I've been looking for a 'scientific' paper for hours (need for reliable references) but can't find it...

Any ideas?

Thanks ahead!

P.S: If my post is not at the right place, do not hesitate to move it ;)
 
Engineering news on Phys.org
The cost of downtime mainly depends on the cost of replacement power for the region (compared to the what you were selling your nuclear megawatts for). $1 million euros per day is a reasonable ball-park figure. Some factors which would affect the price would be having to buy replacement power from a neighboring utility or country; if you have to run oil or gas-fired power plants when fuel prices are high; or if electricity demand is high (e.g. peak of summer or winter).
 
Thanks for your answer, you gave me a very interesting clue!

Actually, I have to do some research for a University project and I was looking for an analysis, a study or a 'scientific' paper because I have to expose my references.

Do you know where I could find such documents?
 
I don't know if you are interested information regarding CANDU reactors (or strictly LWR reactors). There is currently a lot of information in the news (that must be getting sources from somewhere) about a CANDU reactor in eastern Canada which is currently being refurbished. The project went very poorly and much of the work needs to be re started. The controversy is who should cover the cost of the replacement power due to the downtime. The news frequently uses "over a million dollars a day (Canadian)" when talking about how much it is costing to import the power from other areas.

Keeping in mind that the replacement power is only one component of the cost of downtime. I don't know of any scientific papers, but this might give you a direction for your research, the Wikipedia page for the plant is:
