10 years ago We have now implemented different carrier salts into the pstudy. In each of the salts we test the four major fissiles in each of the two major fertiles at a 1.8%(atom fraction) enrichment. Each salt solutions has 6%(atom) Actinides concentration. The modified salt solution density is based mainly on 1000 K unmodified density from: http://web.ornl.gov/~webworks/cppr/y2006/rpt/124584.pdf?origin=publication_detail with .7 g/cc added to account for the heavy isotopes. (This is based on linear fit between test results on LiF-BeF2-ThF4 with different Th fractions - along with some modeling. Results from the different studies mentioned in the issue header).
The now implemented salts are the major candidates for AHTR cooling salts (except a few, which has bad neutrons properties, e.g. the potassium salts)
The salts are: LiF-BeF2-AcF4 (70-24-6) 2.64 g/cc LiF-NaF-BeF2-AcF4 (31-31-32-6) 2.70 g/cc RbF->ZrF4-AcF4 (52-42-6) 3.92 g/cc NaF-ZrF2-AcF4 (54-40-6) 3.84 g/cc LiF-NaF-ZrF2-AcF4 (26-31-37-6) 2.74 g/cc
We need to construct some model for salt densities - i will make an issue on this.
We should start some neutronic investigation of fuel carrier salts, here are three major links, we need to figure out what is best... http://moltensalt.org.s3-website-us-east-1.amazonaws.com/references/static/downloads/pdf/ORNL-TM-2316.pdf http://web.ornl.gov/~webworks/cppr/y2006/rpt/124584.pdf?origin=publication_detail http://web.ornl.gov/info/reports/1973/3445605559801.pdf
Which is you favorite salt?
