| Aperçu général : | The ex cathedra part of the course covers the following main topics:
- Corrosion phenomena: description and occurrence
- Electrochemical and chemical study of corrosion problems: basic equations, user diagrams and practical examples
- Detailed study of frequently occurring corrosion types (e.g. pitting, IGA, SCC, ...): setting
and context, explanation, influences of the environment and material properties
- Methods of corrosion prevention and protection (design aspects, coatings, water treatment and inhibitors, electrochemical methods)
- Effects of radiation on corrosion (e.g., irradiation assisted corrosion)
- Corrosion problems in nuclear reactors: material behaviour and material requirements, technological aspects and environment-sensitive damage, with emphasis on light water reactors, in general, and steam generators, in particular
- Reactor pressure vessel life management: material degradation issues, legal context, advanced analysis and mitigation
- Fuel cladding and stainless steel degradation under irradiation
- Advanced treatment of irradiation effects in materials: radiation damage mechanisms at microscopic level
Some of these topics are further elaborated during seminars and visits to the SCK*CEN laboratories (incl. hot cells).
- Basic measurements: source strength, neutron flux (activation analysis, neutron counting), neutron spectrum (time of flight methods, unfolding methods), reaction rates
- Activity, dose and cross-section measurement
- Measurement of neutron transport parameters: stationary methods, pulsed neutron experiments
- Measurement of reactivities (and reactivity coefficients): survey, static methods, dynamic measurements, inverse kineticsStatistical fluctuation method: reactor noise, mathematical
analysis, applications (Rossi-alpha, sign correlations, zero crossings)
