New Nuclear Power Generation in the US

Click For Summary

Discussion Overview

The discussion centers on the announcement of new nuclear power generation in the United States, particularly focusing on the potential implications for energy policy and the concept of a "Nuclear Renaissance." Participants explore various aspects of nuclear power generation, including the construction of new reactors, manufacturing capabilities, and industry challenges.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants express optimism about the announcement signaling a potential "Nuclear Renaissance" in the US.
  • Questions arise regarding the position of specific stakeholders, such as Kinky, on the new plant developments.
  • Concerns are raised about the manufacturing capabilities of US companies for reactors and reactor components, with references to historical manufacturing halts and tariffs on foreign components.
  • One participant notes that Palo Verde was originally designed for five units, with some recollection of plans for ten units, indicating a potential for expansion.
  • Technical discussions include the impact of replacing aging components on reactor performance and safety, referencing specific incidents like the Davis Besse Head failure.
  • There is a mention of the nuclear industry's stance on greenhouse gas emissions and its role in promoting nuclear energy as a cleaner alternative to fossil fuels.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple viewpoints regarding the implications of new nuclear power generation, manufacturing capabilities, and the industry's response to environmental concerns.

Contextual Notes

Limitations include uncertainties about the current state of reactor manufacturing in the US, the historical context of component production, and the specific technical details regarding reactor safety and performance improvements.

New Nuclear Power Generation in the US Announced!

I posted about this in the Nuclear Engineering Forum, but this may signal the "Nuclear Rennaisance" in the US, so I'm repeating here for discussions on energy policy rather than technology.

What is Kinky's position on the new plant?
 
The Palo Verde Nuclear power station west of Phoenix has announced that they want to build two more reactors to add to their existing three.

Is any company in the USA still making reactors or reactor components?
Below is the only link I could find and it indicates that we haven't manufactured anything since 1999. It also stated that as of nov 2005 American companies had to pay a tariff to buy foreign components.

The oil and coal lobbyists in Washington are going gto be busy.

Palo Verde was designed for 5 units, although I believe I remember someone saying ten units.

[QUOTE-NEI]Steam generator, pressurizer and vessel-head replacements can improve reactor performance dramatically by reducing downtime and increasing electrical output.[/QUOTE] That is if the plant is derated over concerns of failure of aged parts. These components were supposedly designed for 40 year lifetime. In some cases, the internal started failing before they reached half-life. :rolleyes:

PV head replacements are motivated by the near failure of the Davis Besse Head. Corrosion and a steam leak wore away the carbon steel shell leaving about 5/8" (IIRC) stainless steel liner holding back about 2230 psia. It would have been a nasty situation if that liner had failed.

Interestingly, the nuclear industry is considered fairly conservative, as is the utility industry. However, the nuclear industry supports the claim that GW is in large part caused by fossil fuels (the utilitiy industry also uses a lot oil and coal), and they promote nuclear energy as a way to meet demand for electricity and reduce greenhouse gases. :smile:
