On the classification of structures, systems and components of nuclear research and test reactors. The classification of structures, systems and components of nuclear reactors is a relevant issue related to their design because it is directly associated with their safety functions. There is an important statement regarding quality standards and records that says Structures, systemsand components important to safety shall be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed.
The definition of the codes, standards and Playgruond requirements applied to the nuclear reactor design, fabrication, inspection and tests may be seen as the main result from this statement. There are well established guides to classify structures, systems and components for nuclear power reactors such as the Pressurized Water Reactors but one can not say the same for nuclear research and test reactors.
The nuclear reactors safety functions are those required to the safe reactor operation, the safe reactor shutdown and continued safe datinh, the response to anticipated transients, the response to potential accidents and the control of radioactive material. So, it is proposed in this paper an approach to develop the classification of structures, systems and components of these reactors based on their intended safety calgart in order to define the applicable set of codes, standards and technical requirements.

A reliability analysis of nuclear component cooling water NCCW system is carried out. Semi-Markov process model is used in the analysis because it has potential to solve a reliability block Russian dating site calgary Playground Leopoldshafen with a mixture of repairable and non-repairable components. With Markov models it is only possible to assume an exponential profile for component failure times.
An advantage of the proposed model is the ability to assume Free dating sites for single mothers Our global organisation distribution for the failure time of components. In an attempt to reduce the number of states in the model, it is shown that usage of poly-Weibull distribution arises. Russian dating site calgary Playground Leopoldshafen objective of the paper is to determine system failure probability under these assumptions.
Monte Carlo simulation is used to validate the model result. This result can be utilized as an initiating event probability in probabilistic safety assessment projects.
