About this exam

The Principles and Practice of Engineering (PE) Nuclear exam is one of more than 20 PE exams administered by NCEES. It is a licensure examination that tests for a minimum level of competency in nuclear engineering, and it is designed for engineers who have gained a minimum of four years of post-college work experience in the discipline - not for students or recent graduates. Passing the exam is normally one component of a broader licensing process: each state, territory, or international licensing board sets its own education, experience, and application requirements, and candidates should confirm those directly with the board that will issue the license.

The exam samples the breadth of nuclear practice rather than a single specialty. Expect items spanning plant systems and components, reactor physics and criticality, thermal-hydraulics and heat transfer, radiation protection and shielding, the fuel cycle and waste management, safety and licensing, plant operations and testing, and materials, instrumentation, and control. Problems tend to be quantitative - design calculations, operating-condition evaluations, and regulatory reasoning - rather than pure recall.

Preparation usually combines a structured review of each topic area with timed practice under exam conditions, plus familiarity with the reference materials and calculator policy NCEES permits. Because exam specifications are revised periodically, build your study plan from the current NCEES Nuclear exam specifications and reference list rather than from older third-party outlines.

Common questions

About PE Nuclear preparation

Who is the PE Nuclear exam intended for?

It is designed for engineers who have gained a minimum of four years of post-college work experience in their chosen engineering discipline. It tests for a minimum level of competency in nuclear engineering. Eligibility to actually sit for it is set by your licensing board, so confirm education and experience requirements there before you register.

How is the exam scored, and will I see a numeric score?

All results are reported as pass or fail. If you fail, you receive a diagnostic report showing your performance for each of the major topics covered on the exam. You will not receive a diagnostic report if you pass. Use the topic-level breakdown to target your next attempt.

How soon are results released?

Exam results are typically available within 7–10 business days. You receive an email notification from NCEES with instructions to view your results in your MyNCEES account. The results page also links to your licensing board for state-specific information or instructions.

If I fail, how soon can I retake the exam?

NCEES policy states examinees will be provided one attempt per testing window and no more than three attempts in a 12-month period. Plan your study cycle around that constraint rather than assuming you can retest immediately after an unsuccessful attempt.

How do I register and pick a test date?

Examinees register and schedule appointments through their MyNCEES accounts. During registration you select your exam location and are then presented with a list of available exam dates. If you are not happy with those choices, you can browse available dates at other NCEES-approved test centers.

Is the exam computer-based?

Yes. NCEES directs examinees to the computer-based exams section of the NCEES Examinee Guide for information about cancellations, refunds, rescheduling, and discipline changes, and it maintains a list of test center locations. Check the Examinee Guide and test center pages for current delivery details before exam day.

How long is the exam and how many questions does it have?

Those figures are not stated on the NCEES PE exam page summarized here, so treat any number you see elsewhere as unverified. Consult the current NCEES Nuclear exam specifications and the Examinee Guide for the authoritative format, item count, and appointment length before you build a timed practice plan.

What is the most common way candidates lose points?

Two patterns dominate. First, uneven preparation across topic areas - candidates over-study reactor physics and under-study operations, materials, and licensing content that carries comparable weight. Second, pacing failures: spending too long on one multi-step calculation and leaving later items unanswered. Practice full-length timed sets, and learn to flag and move on.

Are testing accommodations available?

Yes. Reasonable accommodations are available for examinees who meet certain eligibility criteria and sufficiently document their request. Because documentation takes time to assemble and review, start the request well before your intended testing window rather than after you have scheduled an appointment.

What should I study first?

Start with the topic areas where you have the least day-to-day plant or design experience, since those decay fastest and are hardest to self-teach. Then cycle through all areas in short, repeated passes with quantitative practice problems, finishing with full-length timed simulations in the final weeks.
