[en] Lesson 1 Objectives Review risk and reliability concepts and show how they relate to human error Review significant nuclear incidents and underlying human error Review standard terminology in HRA review brief history of HRA and different HRA methods

[en] Resonance system for a cyclotron is described. It contains inside and outside conductors, accelerating electrode and operating frequency control system. The operating frequency control system is accomplished in a form of a resonator volume filled with liquid conductor and supplied with the system of liquid conductor level control to simplify the design and rize the operation reliability

[en] We present a local convergence analysis of a two-step and derivative-free Kung–Traub’s method, which is based on a parameter and has fourth order of convergence. Using basins of attraction of the method, dynamical behavior of the scheme is studied and the best choice of the parameter is found in the sense of reliability and stability. Some illustrative examples show that as the parameter gets close to zero, radius of convergence of the method becomes larger.

[en] Accelerating system of a cyclotron is described. The system comprises four dees and two mechanically stiff current-conducting buses connecting dees in pairs. To simplify the design and to increase cyclotron operation reliability the buses are connected by theip central parts to a common jumper fixed on a resonance line rod. A possibility of the usage of one resonance line with one device for frequency control in the four-dee accelerating system increases operation reliability and simplifies cyclotron design as a whole. One high-frequency generator is needed for the system supply. The arrangement for an accelerating voltage phasing on dees is not necessary

[en] This memorandum reports on the conclusions of the tests carried out in order to evaluate the reproducibility of ultrasonic tests made on welded joints. FRAMATOME have started a study to assess the dispersion of results afforded by the test line and to characterize its behaviour. The tests covered sensors and ultrasonic generators said to be identical to each other (same commercial batch)
