I'm the first one, and I was just asking for information. I thought that was one of the purposes of this forum.<BR/><BR/>My job requires me to be anonymous when posting to blogs. Not sure why you feel the need to make it a manhood issue?<BR/><BR/>I was simply asking for more information about MSR R&D post-1960s, and you somehow decided I was outside your door with protest placards. This sort of reflexively defensive posture will not serve the industry well as its moves into the nuclear renaissance era. It doesn't fly with the public.<BR/><BR/>I'd still like to see some citations for the long list of advantages you cite in your most recent post. I'll check out the sources you do mention.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10911751.post-49455091193745119252009-02-24T11:17:00.000-05:002009-02-24T11:17:00.000-05:00Hey Charles, Anon#2 is agreeing with you about the...Hey Charles, Anon#2 is <I>agreeing</I> with you about the potential cost of MSR technology, with the caveat that there's as yet no fully worked-out design to point to.Billhttps://www.blogger.com/profile/08749459207189576328noreply@blogger.comtag:blogger.com,1999:blog-10911751.post-51880266274998588252009-02-23T19:22:00.000-05:002009-02-23T19:22:00.000-05:00Two Anonymous comments?

Moir of Lawrence Livermore National Laborator<BR/>Nuclear Technology 138 93-95 (2002)10/2/2001 <BR/>I have discussed numerous cost savings measures that Moir did not consider. See discussions in Nuclear Green, May 2008<BR/><BR/>Anonymous 2 relies on the circular argument that since there are no MSR research projects, there should be no MSR research, in fact MSR research is geing conducted in Russia and France. Your assertion that there are no cost advantages to MSR in comparison to Advanced High Temperature Reactor reactors. in fact MNSRs, have superior neutron economy because of continuous FP stripping. MSRs have superior safety because of of their negative coefficient of reactivity, and they are capable of both load following and serving in peak reserve capacity. MSRs can be mass produced, significantly lowering unit price, Finally, MSR fuel can be continuously reprocessed as can blanket salt. The cost of MSR fuel reprocessing is a small fraction of the price of solid fuel reprocessing. Additionally there is no fuel fabrication/refabrication expense.Charles Bartonhttps://www.blogger.com/profile/01125297013064527425noreply@blogger.comtag:blogger.com,1999:blog-10911751.post-50881595249029860812009-02-23T15:52:00.000-05:002009-02-23T15:52:00.000-05:00There are, as yet, no modern design studies for MS...There are, as yet, no modern design studies for MSRs that would include the new technologies that would likely be used (e.g., closed gas Brayton cycle power conversion rather than a steam cycle). <BR/><BR/>But the capital cost of a MSR would be very similar to the solid-fuel variant called an Advanced High Temperature Reactor (AHTR), which the DOE has been studying. Oak Ridge National Laboratory issued a report in 2004 that predicted that AHTRs would have capital costs appromately 55 to 60% of the cost of modular helium reactors (MHRs) and sodium fast reactor (SFRs).<BR/><BR/>So yes, it is likely that MSRs could be substantially less expensive than other types of reactors.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10911751.post-76446748293057661872009-02-23T12:55:00.000-05:002009-02-23T12:55:00.000-05:00"does not consider the possibility of developing M..."does not consider the possibility of developing Molten Salt Reactor technology, despite its potential to be a lower cost alternative to all of the technologies mentioned in the report."<BR/><BR/>Interesting.

All of the energy options considered by "A Strategy for Nuclear Energy Research and Development" are very expensive, and one Carbon Capture and Sequestration is impractical because of the energy input it requires. Were there no lower cost options, this might be acceptable, but the report does not consider the possibility of developing Molten Salt Reactor technology, despite its potential to be a lower cost alternative to all of the technologies mentioned in the report. Isn't the problem here that Molten Salt Reactor technology was not invented at INL, and therefore it gets no attention from INL researchers.Charles Bartonhttps://www.blogger.com/profile/01125297013064527425noreply@blogger.com
