The PHWR CANDU 6 from Cernavoda NPP Unit 2 against the European Utility Requirements (EUR)

In the beginning of 2007 Romania became a country member of the European Union. Within this new context it is necessary to asses the technological level of nuclear field from our country comparatively to the actual requirements for the nuclear field from the member countries of EU. These requirements based on the nuclear field current regulations from the member countries of EU and on their operational experience on LWR Nuclear Power Plant type, were gathered and colligated together in the 'European Utility Requirements (EUR)'. The requirements are structured in chapters and sections related to the main design process, construction and operation of LWR NPP fields. The EUR documents are applicable to the whole plant, up to the external electrical grid, at the limit of the switches which connect the electrical stations to the outside high voltage bus bars. Even the Cernavoda NPP Unit 1 and Unit 2 design is a PHWR CANDU 6 design type, after an analysis it is concluded that the majority of the EUR requirements are available too for this design type. Another goal of this analysis was to evaluate the level of the fulfillment of the applicable EUR requirements by the Cernavoda NPP Unit 2 design and to establish a set of measures which are necessary to implement for current PHWR CANDU 6 design for Unit 3 and 4 in order to be in accordance with all applicable EU standards.
