KEPIC is defined as a set of integrated codes and standards applicable to the entire process of designing, manufacturing, installing, and operating electric power facilities, including nuclear and thermal power plants, to secure their safety and reliability.

KEPIC was developed using international standards applied to domestic standard power facilities, with the resulting code equaling or exceeding technical aspects of the reference standards. Administration requirements are adjusted to suit domestic situations, and QA requirements are differentiated for nuclear and nonnuclear applications.

HSB is the world’s largest authorized inspection agency (AIA) accredited by the ASME. We understand the complexities of small modular reactors, which use advanced technology, including coolants and moderators beyond water. HSB’s experienced engineers and inspectors provide pressure equipment inspections and engineering services to designers, manufacturers, owners, and operators as the nuclear industry adopts SMRs. With experience in ASME, JSME, KEPIC, Canadian Standards, ISO Standards, and Nuclear Third-Party Inspection specifications, our team can address your most difficult SMR development challenges.
