[en] In terms of training for commissioning this appendix is an example of: - Expansion of existing NPP fleet. Mochovce Units 1 and 2 were of the same VVER-440/213 type as the Bohunice Units 3 and 4, which have been operated since 1983-1985. It was an advantage for the Mochovce NPP because many of experienced and trained people from the Bohunice NPP could be recruited for key functions and for other positions at the Mochovce NPP. Another advantage was that new inexperienced Mochovce employees could be trained at the Bohunice NPP during the Mochovce NPP construction. - Significant design change during NPP construction. The original project of the Mochovce NPP was changed during construction. In 1991, the management of the Mochovce NPP decided that the original Process Control System would be replaced by the new one from Siemens AG. After this Project change, the new Control Room Simulator, new training programmes and new training materials had to be developed for training of personnel for commissioning of the Mochovce NPP. All the Mochovce personnel, that had been trained by Bohunice programmes in 1982-1993, had to be additionally retrained by Mochovce training programmes. - Project of delayed NPP construction. The construction of the Mochovce NPP was delayed for several years. The Mochovce NPP construction started in November 1982 and it generally met its schedule until 1989. After the political changes in Czechoslovakia in 1989 (the velvet revolution), some problems around the Mochovce NPP construction occurred (additional safety questions, environmental aspects and financial problems, mainly). In 1993, these problems caused a complete stoppage of Mochovce NPP construction. The construction continued again in 1996 and it was successfully completed at Unit 1 in 1998 and at Unit 2 in 2000. In terms of personnel training for Mochovce commissioning, the project delay had a positive impact, because there was extra time for education and training of personnel for commissioning of the Mochovce NPP
