Class 11–12 subjectsPhysics, Chemistry, Maths

Entrance / admissionJEE Main / JEE Advanced

DegreeB.E. / B.Tech in a core branch + nuclear training

Duration4 years + 1 year training

Your route, step by step

1Class 11–12: take PCMModern physics — atoms and nuclei — in Class 12 is where this career begins; strong Maths is essential.
2Write the entrance examsJEE Main for NITs and many colleges, JEE Advanced for IITs. In Tamil Nadu, TNEA counselling uses your Class 12 marks.
3B.E. / B.Tech Mechanical, Chemical, Electrical or Electronics · 4 yearsIndia has few undergraduate nuclear courses; these core branches are the usual entry.
4Join the atomic energy sectorBARC’s training school (OCES / DGFS) or NPCIL Executive Trainee posts, selected through exams or GATE scores.
5Train and specialisePaid training in nuclear science and reactor engineering, then plant or research roles.

What a nuclear engineer does
