A new neutron-gamma coupled MATXS-format library, which is designated KASHIL-E6, has been generated for shielding or reactor pressure vessel dosimetry applications. The library was tested against the NESDIP-2 experiment for application to the RPV dosimetry. Dosimetry analyses on the surveillance capsules of the Ulchin Unit 1 have been carried out using KASHIL-E6. The analyzed dosimeter reactions are ⁵⁴Fe(n,p), ⁵⁸Ni(n,p), and ⁶³Cu(n,α) at the end of 3^rd, 6^th, and 8^th fuel cycle of the power plant. To demonstrate the differences of dosimetry data in the current evaluated data files, the data from five different files were examined. The calculations for the benchmarks agree with the measurements within 10%. The calculated values of ⁵⁴Fe(n,p) and ⁵⁸Ni(n,p) in the surveillance capsules show differences of 10% from the measurements while those of ⁶³Cu(n,α) are over 20%. Maximum difference on ⁵⁴Fe(n,p) between JENDL-3.2 and JEF-2.2 is 20%.
