PE Nuclear key facts & eligibility
| Conducting body | NCEES (National Council of Examiners for Engineering and Surveying) |
|---|---|
| Official website | ncees.org ↗ |
| Mode | The PE Nuclear exam — the Principles and Practice of Engineering exam for nuclear engineers, toward Professional Engineer licensure. It is a computer-based test at Pearson VUE centres. |
| Frequency | Offered once a year by appointment at approved test centres. |
| Scoring & marking | It has 85 questions (multiple-choice plus alternative item types) in a 9.5-hour appointment (including a tutorial and a scheduled 50-minute break). NCEES provides an electronic reference handbook and specified standards on-screen — the only references allowed. Content covers nuclear power systems, the nuclear fuel cycle, the interaction of radiation with matter (including radiological protection and shielding), and nuclear criticality, kinetics and neutronics. Results are reported pass/fail. |
| Score validity | A pass, with the required experience, leads to PE licensure by your state board. |
| Language | English. |
