Journal Articles

Nuclear quantum effect on the dissociation energies of cationic hydrogen clusters

Sugimoto, Masataka*; Shiga, Motoyuki; Tachikawa, Masanori*

Computational and Theoretical Chemistry, 975(1-3), p.31 - 37, 2011/11

 Times Cited Count:5 Percentile:11.26(Chemistry, Physical)

${it ab initio}$ path integral molecular dynamics based on MP2/cc-pVTZ method has been carried out for a series of small hydrogen cluster cations, H$$_3^+$$, H$$_5^+$$, H$$_7^+$$ and H$$_9^+$$. The dissociation enthalpy for the reaction H$$_3^{+}$$(H$$_{2}$$)$$_{n}$$ $$rightarrow$$ H$$_3^{+}$$(H$$_{2}$$)$$_{n-1}$$ + H$$_{2}$$ is found to be 5.4, 2.1 and 3.2 kcal/mol, respectively, which are slightly smaller than experimental values. It is found that energies of quantum zero-point vibration and anharmonic vibration of the respective cations are important factors that determine the value of dissociation energy.

Latest status on development of long-term fusion nuclear technologies at JAERI is overviewed. A tritium processing system for the ITER and DEMO reactors was designed and basic technologies for each component of this system was demonstrated successfully by an operation of the integrated system for one month. An ultra-violet laser with a wave length of 193 nm was found quite effective for removing tritium from in-vessel components of D-T fusion reactors. Blanket technologies have been developed for the Test Blanket Module of the ITER and for advanced blankets for DEMO reactors. This blanket is composed of Li$$_{2}$$TiO$$_{3}$$ breeder pebbles and neutron multiplier Be pebbles, contained in a box structures made of a reduced activation ferritic steel F82H. Mechanical properties of F82H under neutron irradiation up to 50 dpa were obtained in a temperature range from 200 to 500$$^{circ}$$C. Design of the International Fusion Materials Irradiation Facility (IFMIF) has been developed so as to obtain engineering data for candidate materials for DEMO reactors, under neutron irradiation up to 100-200 dpa.
