摘要：
Boron isotopic ratio measurement is very important in the nuclear industry because it is used as neutron poison (in the form of boric acid or a B4C pellet) and control rod material (B4C pellet) in nuclear power plants. Since B-10 has a higher neutron absorption cross-section, enriched B-10 is used in the nuclear industry and the extent of enrichment varies from 50-90 %. Therefore, it is essential to determine the B-10/B-11 ratio in boric acid and B4C. The prime purpose of the present study is to utilize LA-ICPMS for evaluating B-10/B-11 ratio both in solution (boric acid) and solid (B4C pellet) without any pre-treatment so that the difficulty in dissolution or powdering process of B4C (one of the hardest materials) can be avoided and the B4C pellet can be reused. The results obtained from LA-ICPMS for the B4C pellet are discussed and compared with the solution ICPMS, TIMS, and LIMS. The solutions of boric acid (natural abundance) and dissolved B4C (natural & similar to 67 % enriched isotopic composition) were analyzed by LA-ICPMS and validated by liquid sampling ICPMS data.
