JANSIJapan Nuclear Safety InstituteAbout Us
Based on reflection of the TEPCO Fukushima Daiichi Nuclear Power Station accident, the nuclear industry inJapan established the Japan Nuclear Safety Institute or JANSI in 2012 as a self-regulatory organization, whichfunctions as a civilian third-party organization to encourage operators’ efforts for voluntary pursuit of higher
excellence.
In order to achieve this self-regulation, JANSI and the industry are working as a community to improve nuclear
safety further by ensuring the following points;

CEO’s Engagement※１
Chief Executive Officers are actively engaged in the operation of JANSI, including governance and oversight.

Nuclear Safety Focus
The primary focus is on nuclear safety. There is a clear mission, focused on achieving standards of excellence inoperations.

Support from Industry
The industry fully participates in JANSI activities and provides support in talent and resource.

Accountability
Member companies are accountable for the safety of their station and to JANSI for the collective safety of theindustry.

Independence※2
JANSI is independent of any one group or company, although it is dependent on the collective group ofcompanies.

Board of Directors※1 Board of Directors consisted of all operator CEOs is actively engaged in JANSI activities.
※２ JANSI shares “Principle of Coordination” with operators to ensure its independence and to serve as a powerful driver ofoperators’ safety enhancement activities. “Principle of Coordination” includes authority to be able to recommend shutdown ofnuclear power facilities and free access to operator information.

JANSI’s Mission and Cycle of Activities
In order to achieve effective self-regulation, operators need to take voluntary and continuous measures toenhance safety, strive to attain the world’s highest level of safety (i.e. excellence) in an up-to-date manner and, inpursuit of new heights, work to develop excellence on its own initiative (this is referred as “the pursuit ofexcellence”).
Thus, JANSI drives safety improvement activities under the mission below;～Mission～

Pursue the World's Highest Level of Safety
in Japan's Nuclear Power Industry(~Untiring Pursuit of Highest Standards of Excellence~)

JANSI defines the latest standards of excellence and applies it in the cycle of setting up excellence standards,
evaluating to these standards and supporting the operators in an effective and timely manner for the purposeof achieving its mission.

Visions
In Ten-Year Strategy, the visions (desired end states) of the operator and JANSI are defined based on the currentsituations of JANSI and the operator. JANSI will enhance its own activities with the below JANSI vision as an aim,
while through these activities, achieving the operator vision by driving and supporting the operator.

Visions of JANSI and Operators
JANSI

JANSI leads operators from an
independent standpoint as theauthority of world’s excellence.

Operators

Operators have achieved the world's
highest level of safety and reliability,
and are maintaining and continuingthat state by establishing voluntaryand continuous safety improvement
initiative.
2Formulation of Ten-Year StrategyJANSI and operators identified the desired end statesin ten years and established Ten-Year Strategy in March
2019 as strategies and action plans to realize those endstates and revised it in March 2024.
This strategy clarifies visions of operators and JANSI,
identifies critical success factors for improvement ofstation performance, and establishes main actions toachieve them.
JANSI will work toward these visions together withoperators.
Effectiveness of the activities will be evaluatedregularly based on long-term environmental changes,
and the actions in Ten-Year Strategy will be updated asnecessary.

JANSI Ten-Year Strategy

What is self-regulation we seek?

(FY20-20)

Self-regulation that the nuclear industry seeks
is community regulation led by nuclear operators
working in solidarity with JANSI.

JANSIJapan Nuclear Safety Institute

Striving for Excellence in Nuclear Safety

This concept is represented by a helm of aboat.
At the center of the helm is JANSI. JANSI is
responsible to set the highest standards andfacilitate performance improvement. The grips ofthe wheel are the operating companies who dothe hard work of nuclear excellence every day.
The grips or spokes of the wheel are connected
together forming a community committed toexcellence. At JANSI we value this communityand nurture it.
Monument of a ship’s wheel
The helm of a boat symbolizes the notion “wein the JANSI reception area on the 15th floor
are in the same boat,” which means that thewhole industry is influenced by the performance of each other.
The Ten-Year Strategy is the course by which we chart our journey together. We are guided
by our collective commitment to Excellence in Nuclear Safety.
We are confident in the bright future of the industry as we tirelessly seek the highest standardof excellence and demonstrate a strong commitment and professionalism in the process ofachieving community regulation.
A helm of a boat delivers a message of such belief and determination of ours.

Critical Success Factors and Main Actions of Ten-Year Strategy
Fostering of healthy safety culture
1 Lead the awareness raising of operators as the main actor of self-regulation●JANSI continues to conduct direct interviews with newly appointed CEO/CNOs＊, encourages voluntary andcontinuous pursuit of safety, and elicits strong commitment from the top management of operators toprioritize safety.

＊CNO：Chief Nuclear Officer●JANSI continues providing the operatorswith opportunities to have lectures ofthose who have experienced theFukushima Daiichi accident, video materials, and supports the operators to workfor reflecting and remembering thelessons learned from the accident.

3 Determine/develop organizational effectiveness to maintain and continue highperformance●In the pursuit of sustainability, JANSI aims to incorporate advanced initiatives in organizational effective-

ness evaluation into Japan, while also building and operating approaches appropriate to Japan's unique
circumstances. JANSI advances initiatives in cooperation with WANO.

4Operation of Voluntary Continuous Improvement FoundationProgram
4 Pursuit of world’s excellence●JANSI constantly grasps the world's operating experience and excellence, revises guidelines, etc., andshares with the operators to encourage voluntary improvement, and provides the operators with aneffective platform to promote voluntary improvement in collaboration with the industry.

5 Effective/efficient implementation of high-quality Peer Review●JANSI implements the globally high-quality JANSI Peer Review (domestic voluntary Peer Review) once/fouryears.

●JANSI further strengthens collaboration with WANO by improving its Peer Review capabilities, maintain-ing/renewing WANO equivalency, continuing substitute Peer Review about once/year, etc.

●Under a mid- and long-term plan and in consideration of PMCM effectiveness check, etc., JANSI introduces

the “graded approach Peer Review” (GAPR) which focuses on some review areas when JANSI implements
JANSI Peer Review at model plants.

Explain

PMCM（Performance Monitoring and Continuous Monitoring）

The activities of operators and JANSI (in collaboration with WANO) are aimed at providing timely support for
the early detection of deterioration trends and improvement through the daily monitoring of power plant
performance information.

6 Maturing and effective utilization of PMCM
●JANSI develops and matures PMCM technique and ensures its effectiveness in order for operators tovoluntarily and continuously grasp plant performance, detect signs of decline early, and take prompt
action.
●JANSI provides the operators with effective, efficient and valuable activities as a whole, in which “JANSI
activities” including peer reviews and continuous monitoring of plant performance and “WANO activities”
are harmonized yet remain independent.

57 Continuous improvement of Plant Integrated Assessment●JANSI comprehensively evaluates plant performance, improves the effectiveness of peer pressure andincentives, and makes the system work.
