the Microfield «Repair and atomic power station maintenance service»

It is obvious, that repair and maintenance service processes are carried out not only on atomic power stations, they are necessary for maintenance of normal operation of any technically-difficult objects.

However specificity of use of energy of division of atom leave the mark here again.

For example, base concept for repair carrying out on the atomic power station is outage which on Russian is translated as «Planned

Precautionary repair »(Ш1Р). The etymology of this term is interesting. The matter is that technologically on the atomic power station of types VVER, PWR, BWR an overload of fuel demands ostanova reaktornoj installations (from here - outage, in the developed kind - refuelling outage), for this period plan and carry out all repair work. On the Russian atomic power stations, even on RBMK, not demanding ostanova for an overload of nuclear fuel, this time interval historically is called PPR, on foreign - Outage.Отсюда such terms as outage management (management 11Р), outage optimisation (optimisation of terms NIR), outage schedule (schedule NIR), outage control centre (staff NIR). Without understanding of contextual underlying reason transfer of these terms can cause considerable difficulties.

Organisation NNR structure on atomic power stations is represented on fig. 2.24, this scheme of organisation NIR is taken from operating document MAGATE [NPP OOS: 23], it visually illustrates, that at the head of the project on organisation NNR there is head NNR who directly supervises over the personnel of groups of planning of repair, technical support, the operation personnel directly maintaining the equipment on which repair work will be carried out, repairmen, an estimation of safety and budget formation.

The term maintenance, even in a word-combination planned-preventive maintenanceиспользуется it is direct for a designation of operations of maintenance service and repair on the concrete equipment, for a designation of levels of the general planning and which management the term from terminognezda «Outage» is used. Logic communications in terminognezde «Maintenance» are designated on fig. 2.26.

The structure of the organisation and performance of works on maintenance service and repair is shown on fig. 2.27.

On fig. 2.27, taken from operating document MAGATE [NPP OOS], the scheme of the organisation of works on maintenance service and the repair based on data on reliability is resulted. It visually illustrates lexicon use terminognezda «Maintenance» in practice and supplements the list of the terms resulted on fig. by 2.16 following: Reliability Centered Maintenance (RCM) (maintenance service and the repair based on data on reliability), Condition Based Maintenance (repair on a technical condition), First Line Maintenance (specialised repair), Time Based Maintenance (repair with a binding on time), Calendar Based Maintenance (repair under the planned schedule), Operational Time Based Maintenance (repair under the operation schedule), and also shows one more term of a microfield «Maintenance service and repair» - Reliability Based Information (the information on reliability).

Besides, in the course of repair and atomic power station maintenance service the specific equipment, for example is used a lot of: reactor main joint nut-runner (gajkovert the main socket of the case of a reactor), 6Рисунок it is borrowed from [NPP OOS: 2].

pipeline inspection submarine (a submarine of inspection of a condition of pipelines), reactor manipulator (the manipulator reaktornoj installations), ball-cleaning system (system sharikoochistki), vessel weld joint non-destructive testing instrumentation (equipment of not destroying control of a welded seam of the case of a reactor) and another.

Separately published dictionary or the glossary devoted to questions of the organisation of maintenance service and repair on the atomic power station is not present, but to these questions the steadfast attention is paid by the international organisations, in particular, MAGATE has developed technical document IAEA TECDOC 1806 «Nuclear power plant outage optimisation strategy» and has let out in 2016 its staticized edition [NPP OOS], IAEA TECDOC 1590 «Application of Reliability Centred Maintenance to Optimize Operation and Maintenance in Nuclear Power Plants» [RCM] which contain small thematic glossaries.
