Verification of tritium production evaluation procedure using Monte Carlo code MCNP for in-pile test of fusion blanket with JMTR

摘要

To evaluate exactly the total amount of tritium production in tritium breeding material during in-pile test with JMTR, the 'tritium monitor' has been produced and evaluation of total tritium generation was done by using 'tritium Monitor' in preliminary in-pile mock-up, and verification of procedure concerning tritium production evaluation was Conducted by using Monte Carlo code MCNP and nuclear cross section library of FSXLIBJ3R2. Li-Al alloy (Li 3.4 Wt./100, 95.5/100 enrichment of 6_Li) was selected as tritium monitor material for the evaluation on the total amount of Tritium production in high 6_Li enriched material.
