Better Heat Transfer in PWR
Better Heat Transfer in PWR
(OP)
I came across this invention that improves heat transfer in a Pressurize Water Reactor.

Does anyone know if any PWRs actually have plans to use nanoparticles to enhanced heat transfer?
Is it wise to operate the reactor beyond conventional thermal limits?

RE: Better Heat Transfer in PWR
In regard to whether it is "wise" to operate a reactor beyond conventional thermal limits: It depends. ... in order for a reactor in the US to increase its thermal power level, it would need to get a license amendment (or a new license if it is a new plant) from the Nuclear Regulatory Commission. As part of getting that license, the applicant would have to provide extensive documentation to show the safety of the reactor operation. Whether the NRC's review would be sufficient for it to be "wise" probably depends on who you ask. There are some people who believe that the current thermal limits are "unwise" and unsafe. There are others who will claim that the current thermal limits are overly conservative. Still others will tell you that the NRC is extremely conservative or maybe it's "just a tool of the industry."
What all this boils down to is that wisdom, like beauty, is in the eye of the beholder and is not a good measure to use to judge the scientific merit of a process.
