Assessment Of Compliance

In 2007–2008, the European Utility Requirements (EUR) works have been focused on volume 3 (evaluation of the available Gen 3 designs) and volume 4 (conventional island). The works on the AP1000 and AES92 subsets of the EUR volume 3 have been concluded at the end of 2007. The texts have been published and are now available for the EUR members and other utilities. The works on the EPR subset of volume 3 have resumed in 2007. A revision B is being produced for which representatives from ten EUR utilities and from Areva NP have been involved in the revision of the analysis of compliance. Meetings of the specific EUR coordination group in charge of this task have been organized every 4–5 weeks throughout 2008. The revised version of the EPR subset of the EUR volume 3 should be finalized around mid 2009. The revision C of the EUR volume 4 is now available after a thorough review has been performed within the EUR organization to make it consistent with the revision C of the EUR volume 2 published in 2001. A lot of preparatory material for a possible revision D of the EUR volumes 1 and 2 has been produced since 2002. Since important contributions are not yet available the decision to integrate this revision D is still to come. The EUR organization has kept enlarging: Energoatom, ENEL and Endesa have been welcomed as full members; CEZ and MVM are now EUR associated members. New LWR projects of potential interest for the EUR utilities are being contemplated. For instance a preliminary assessment of compliance of MHI’s APWR project has been worked out in the first months of 2008. Recently the EUR and ENISS organizations have decided to join their efforts in a collaboration scheme in which they will coordinate their positions and actions in nuclear safety with respect to the LWR Gen3 designs. The two organizations will cooperate in their relations with the other stakeholders, in particular with the IAEA and WENRA organizations. In addition EUR and CORDEL (Cooperation in Reactor Design Evaluation and Licensing), which is a WNA (World Nuclear Association) working group decided also to coordinate their efforts for the industry benefit, in relation with the MDEP (Multinational Design Evaluation Program) initiative of safety nuclear regulators.

The aim of this work is to develop approaches for a methodology creation that allows estimate preliminary assessment of the power consumption management potential in the absence of experimental data on the object under actual load study. Analysis of diesel power plants operating modes in such systems showed that diesel generators often operate in suboptimal load ranges, which leads to increased diesel fuel consumption, reduction in diesel generators service life andas a result of poor diesel fuelcombustion in the cylinders or increased mechanical parts wear, etc. At the same time, electricity demand management technology used in large centralized power supply systems in some countries of the world can be adapted for use in isolated low power systems. Considering that diesel power plants are the sources of distributed generation in the power systems of hard-to-reach facilities in mountainous areas, demand management will allow to align the daily load schedule, plan the loading, start-ups and stops of diesel generators to improve the technical, economic and environmental performance of the entire complex. This paper proposes a technique that allows estimate preliminary assessment of the object shiftable electrical load share on the basis of "base" data about a typical similar object. The initial data isthe average electrical load daily schedules for each month of the studied object, for example, a settlement. The schedule of non-shiftable partof the studied object load is constructed by scaling the base non-shiftable load schedule depending on the selected method: the series values of base schedule can be multiplied by a coefficient so that one of the base schedule values becomes equal to the corresponding series value of the studied object load schedule, and other base schedule values were less than or equal to the corresponding values. According to the second method the base schedule values can be multiplied by a coefficient so that the series values at the selected hour (for example, evening maximum) were equal to the corresponding series value of the studied object load schedule. An example of methodology application is shown to estimate the demand response potential for electricity in the Amderma settlementresidential sector in Arkhangelsk region. It also shows the calculation results of technical, economic and environmental effect of the demand side management technology, due to electric load schedule alignment and, as a result, diesel generators operationin modes close to optimal.
