I WRITTEN EXAMINATION — 2024/01/23 O PART A O PART B Surname: Name: CODE: PLEASE USE CLEAR WRITING (PART-A) EXERCISE #1. A utility operates two nuclear power stations: one is hosting a large reactor (API 000) while the other one is hosting 4 SMR units (BWRX-300). Assuming the data reported in the Table, what is the power station offering the cheapest cost of electricity (€/MWhe)? Parameter Power plant output, net (MWe) Power plant efficiency, net Load factor Fuel cycle length (months) Num. tycle lengths per fuel assembly enrichment, wt% 'Cm e, num. of fuel assemblies assembly type /•Jum. oi equivalent fuel rods per assembly Active length of fuel rods (mm) Fuel pellet diameter (rnrn) IJ02 theoreticai density (g/cm3) Fuel pellet density, % of theoretical Economy of scale law: exponent cost (€/y) Capital cost interest rate (%/y) molar mass O (g/mol) molar mass 235 1--1 (g/mol) molar mass (g/mol) BWRX-300 290 32% 95% 24 3 3.40% 240 10 x 10 87 3800 8,19 10,96 0.62 25 000 000 4% 15.9994 235,0439 238.0508 Fuel costs Natural uranium (€/kgHM) Conversion (€/kgHM) Enrichment (€/SWU) Enrichment work (SWU/kgHM) Depleted U storage (€/kgHM) Fabrication (€/kgHM) Interim storage (€/kgHM) Disposal spent fuel (€/kgHM) Power plant output, net (MWe) Power plant efficiency, net Load factor Burnup (MWt d/tHM) Fuel cost (€/kgHM) O&M cost (€/y) Capital cost interest rate (Wy) Specific construction capital cost (€/kWe) Both NPPs operational lifetime (y) BWRX-300 80 10 160 4,1 200 470 1117 33% 2400 70000000 6% 5000 60 (optional) #2.
