HKIE Professional Assessment - Nuclear Discipline study guide
HKIE Professional Assessment - Nuclear Discipline · Work through your exam, one topic at a time.
The HKIE Professional Assessment in the Nuclear Discipline is the route by which a trained engineer demonstrates to the Hong Kong Institution of Engineers that they can practise independently at professional level in nuclear engineering. It is intended for engineers who have completed the Institution's structured training or an equivalent scheme and who work, or intend to work, in nuclear power, radiation protection, radioactive waste management, decommissioning, regulatory bodies or supporting consultancies. The HKIE Professional Assessment - Nuclear Discipline study guide has 10 sections and about 4,475 words.
01Nuclear Physics and Reactor Theory Fundamentals
This domain tests neutronics and core physics: how fission releases energy, how a chain reaction is sustained, and how reactivity is quantified and fed back. Binding energy per nucleon peaks near iron-56; fission of U-235 releases about 200 MeV, or roughly 3.2×10^-11 J per fission.
421 words, about 2 min02Nuclear Reactor Systems
This domain tests how major reactor systems work together: primary coolant, pressure control, heat removal, containment, reactivity control and emergency cooling. A PWR has a high-pressure primary loop, usually around 15.5 MPa, with a pressurizer, steam generators and a separate secondary loop.
438 words, about 2 min03Thermal-Hydraulics and Safety Analysis
This domain tests heat transfer, two-phase flow, critical heat flux, accident progression and the acceptance criteria used in safety analysis. Fuel heat flux q″ is related to linear heat rate q′ by q″ = q′/(πD), where D is the fuel-rod diameter.
440 words, about 2 min04Radiation Protection, Shielding and Dosimetry
This domain tests dose quantities, limits, ALARA, shielding calculations and practical dosimetry in nuclear facilities. Absorbed dose is measured in gray (Gy); equivalent dose uses radiation weighting factors and is measured in sievert (Sv); effective dose applies tissue weighting factors and is used for stochastic risk.
425 words, about 2 min05Nuclear Safety, Licensing and Regulatory Framework
This domain tests the safety case, defence in depth, licensing stages and the regulator's role in permitting and oversight. IAEA safety standards provide the international framework: fundamental safety principles, requirements for facilities, and guidance on safety assessment.
391 words, about 2 min06Radioactive Waste Management and Decommissioning
This domain tests waste classification, conditioning, storage, disposal and the planning of decommissioning. Waste is classified by activity concentration, half-life and heat output: exempt or clearance, very low-level, low-level, intermediate-level and high-level waste.
368 words, about 2 min07Nuclear Fuel Cycle and Materials
This domain tests the front end, reactor fuel performance and the back end of the fuel cycle, including material degradation mechanisms. The front end includes mining, milling, conversion, enrichment and fuel fabrication.
371 words, about 2 min08Instrumentation, Control and Electrical Systems in Nuclear Facilities
This domain tests nuclear instrumentation, reactor protection logic, control systems and the electrical supplies that support safety functions. Neutron flux is measured by source-range, intermediate-range and power-range detectors.
402 words, about 2 min09Probabilistic Safety Assessment and Risk Management
This domain tests how fault trees, event trees and reliability data are used to estimate core damage frequency and to support risk-informed decisions. An event tree starts from an initiating event and follows accident sequences through success or failure of safety functions.
402 words, about 2 min10Emergency Preparedness and Response
This domain tests emergency classification, protective actions, monitoring, communication and exercises for a nuclear or radiological emergency. Emergency classification typically moves from alert to site-area emergency to general emergency.
