A spallation neutron source of mercury has been operated in the Materials and Life Science Experimental Facility of J-PARC. A stainless vessel containing mercury during the operation has been exchanged periodically. During the exchange work, tritium release has been observed. The behavior and an analysis from a viewpoint of tritium absorption and emission from stainless steel are reported.
