Projected pay for 原子力技術者 (3, 5 and 10 years)est.
Today ¥6.12M → in 3 years ¥6.44M → in 5 years ¥6.67M → in 10 years ¥7.26M (10-year range ¥6.24M–¥8.43M). The model assumes pay growth of +1.7% per year.
What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →
Outlook score for 原子力技術者
Each component is a percentile rank among all occupations in the same country (0–100). Weights: labor demand 25, wage momentum / openings 15, pay level 15, AI resistance 25, aging workforce 10 (Japan only), entry barrier 10.
Will AI replace 原子力技術者? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 原子力技術者
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.

Guidance from job tag (Japanese)
原子力発電所を有する電力会社では、工業系の高校・専門学校卒業者を運転技術者として育成するコースも整備されており、入職してからも各種養成機関で知識や技術の習得ができる。運転技術者になるには原子炉主任技術者の下で運転員として訓練を積み技術を習得する。技術の習得には10年ほどを要する。その後管理職を目指すが、責任者になるには原子炉主任技術者の資格が必要となる。
関連資格として国家資格の「放射線取扱主任者」、「核燃料取扱主任者」、「原子炉主任技術者」、「技術士（原子力・放射性部門）」がある。
原子力は適正な取扱いが必要とされるので、正確さ、精密さ、判断力、探求心が求められる。また、物理学、化学、数学、電気・機械など基礎工学の知識のほか、海外からの情報も多いので、語学力も必要とされる。
