The Nuclear Regulation Authority (NSA) assailed Japan Proton Accelerator Research Complex (J-PARC) staff on June 26 for continuing to run experiments after a radiation leak.
The final report on a June 20 on-site investigation -- submitted on June 26 -- found that J-PARC's hadron experiment facility continued to operate for four hours after a May 23 radiation leak. Furthermore, an adjacent lab for material and biological experiments went on using the same particle accelerator until 12:45 a.m. on May 25.
The report also noted that an exhaust fan that allowed radiation to escape was kept running for around three days after the accident.
Employees at J-PARC -- operated by the Japan Atomic Energy Agency -- "were not sufficiently prepared for the accident," the NRA investigative report concluded.
