29 29 Possible Options to be Analyzed Cutting-off consumers if unit forced outage is happened. Construction of pump storage hydro plan. Construction of electrolyzes for hydrogen generation that can be used as raw materials for production of fertilizers. Export electricity Other option

30 30 Integration of nuclear power into the Belarus electricity and centralized heat supply system comprised the following tasks: An assessment of recent electricity and heat demand projections and scenarios, and, if necessary, their extension up to the year 2035; Based on the demand assessment, selection of electricity and heat demand scenarios for this study; Collection and evaluation of historical electricity and heat load characteristics and development of specific load curves for this study; Collection of techno-economic performance data and characteristics of existing electricity and heat generation units as well as transmission and distribution infrastructures; Development of base year (2005) electricity and centralized heat balances; Preparation of MESSAGE specific data inputs; Calibration of the model to satisfactorily reflect the base year electricity and centralized heat balances; Selection of a menu of new technology options for the study period Application of MESSAGE for the development of optimal electricity and heat supply strategies, capacity expansion plans, taking into account all available supply options including rehabilitation of existing plant and equipment.

31 31 Scenarios Business-as-Usual (BAU) Scenario continues to rely on current types of fuel imports, fosters rehabilitation of malfunctioning and aging plant and equipment or replacement by new high- efficient gas-fired combined cycle and gas turbine plants as well as dual large and small fuel boilers. Coal (CG) Scenario considers new coal plants for the diversification and expansion of the power system in addition to the options listed under BAU. Nuclear Policy (NP) Scenario extends the CG scenario and includes the potential addition of up to MW of nuclear generating capacity with first grid connection not before Technology (TECH) Scenario considers all technological options without any absolute capacity limitation.

40 40 Part 3 Economic assessment using the INPRO methodology

41 41 Objectives of the INPRO project To perform a full-scope NESA for Belarus according to IAEA in all seven INPRO areas: NPP and NFC Safety, Infrastructure, Proliferation Resistance, Physical Protection, Waste Management, Environment and Economics, To identify follow up actions for implementation of nuclear power in Belarus and to confirm that the strategic plan for Nuclear Energy Deployment is sustainable. 41

42 42 Expected output A Belarus National NESA report is assumed to be included in the INPRO data base as a comprehensive reference case. The Belarus NESA report will have a structure similar to the reports from existing assessments and will contain detailed results of assessments of the planned NES deployment in all INPRO areas.
