A common group cross-section library JSSTDL based on Japanese Evaluated Nuclear Data Library, Version 3 Revision 2 (JENDL-3.2) has been updated in Japan Atomic Energy Research Institute (JAERI) under the cooperation of the Working Group on Standard Group Constants affiliated by the Subcommittee of Group Constants of Japanese Nuclear Data Committee (JNDC). Up to now, JSSTDL-295 based on JENDL-3.2 was developed for shielding applications, however some users pointed out a difficulty of the JSSTDL-295 for applying configurations including polyethylene slabs. It was caused from inadequate group structure for the thermal energy region and the weighting function. In the update version of JSSTDL (JSSTDL-300), we increased number of thermal energy groups from 5 to 10, and also determined the energy boundaries much carefully. The JSSTDL-300 was tested with various shielding benchmark problems, and the validity was confirmed. The integral test scheme established in JNDC was applied in this study. In the present paper, we describe the result of integral test of JSSTDL-300 for applying benchmarks of Japanese-American Shielding Program for Experimental Research (JASPER). It has been concluded that JSSTDL-300 is highly applicable for shielding applications such as configurations in which thermal neutrons were enhanced.
