Permission: NISA examines application documents of basic design of a nuclear facility whether its site location, design of structures and systems, etc. is appropriate to prevent from nuclear disaster.

Approval: NISA examines application documents of detailed design of the permitted nuclear facility whether its practical design and construction method is conform to the Technical Standards.

Inspection: NISA performs inspections for investigating nuclear facilities on its conformity to the Technical Standard periodically and operational safety activities on its conformity to Operational Safety Program.

If necessary, NISA perform on-the-spot inspection.

Approval: NISA examine application documents on decommissioning plan of terminated nuclear facility.
Confirmation: NISA confirm decommissioning work along the approved Decommissioning Plan.

Object facilities of NISA’s regulation are; Nuclear Power Plant （Commercial Nuclear Power Plant and Prototype Nuclear Power Plant）, Fuel Fabrication Facility, Uranium Enrichment Facility, Spent Fuel Reprocessing Facility, Spent Fuel Interim Storage Facility, Radioactive Waste Storage Facility, Radioactive Waste Disposal Facility.

To ensure safety of nuclear facility, NISA also perform Pre-Service Inspection, inspect whether construction work is done along the approved Construction Plan （or Design and Construction Method for fuel cycle facility） and the Technical Standards, and NISA’s Operational Safety Inspector performs daily plant walk-down, incident response activity, etc.

Nuclear Emergency Preparedness and Response, Safety Research, Public Relations activity on Nuclear Safety and Information disclosure for enhancing transparency of safety regulation are also recognized as NISA’s duty.
In international cooperation area, NISA joins international organization’s activity, maintains bilateral or multilateral cooperation.
