<p class="NoSpacing1">SMR NPP is an alternative to overcome the dependency to diesel power plant especially in outside Java Bali system. Economic analysis is a crucial thing that should be done prior to any investment decision on the SMR NPP project and generally done by calculation of Levelized Unit Electricity Cost (LUEC). NPP projects, include SMR, are vulnerable to a number of uncertainty variables. The goal of this study was to perform economic analysis of SMR NPP project with capacity 2 x 100 MWe in Indonesia by incorporating an amount of uncertainty variables, namely the probabilistic approach. The research method is calculating LUEC with deterministic approach followed by the probabilistic approach. Probabilistic approach is done by simulating the effect of uncertainty variable on LUEC using Monte Carlo simulation technique. The results show that the deterministic approach with a discount rate of 10% obtained LUEC at 12.87 cents US$/kWh. Whereas the probabilistic approach obtained LUEC of 13.10 plus minus 1.43 cents USD/kWh at a discount rate of 10% and amounted to 8.11 plus minus 0.88 cents USD/kWh at a discount rate of 5%.  calculation in deterministic approach was  12.87 cents USD/ kWh. While LUEC as the results of uncertainty variables simulation on probabilistic approach were 13.10 ± 1.43 cents USD/ kWh on discount rate 10% and 8.11 ± 0.88 cents USD/kWh on discount rate 5%. Occurrence probability of LUEC is less than 13 cents USD/kWh (benchmark value) was about 100% on discount rate of 5% and  50% on discount rate of 10%.<a href="file:///C:/Users/Mohamad%20Mostafa/Desktop/Knowledge%20E/In%20Press%20Conferences/ICoNETS-2015/Source-Manuscripts/19_L04-Nuryanti_p128-135.docx#_msocom_1">[P1]</a> </p><div><hr align="left" size="1" width="33%" /><div><div><p> <a href="file:///C:/Users/Mohamad%20Mostafa/Desktop/Knowledge%20E/In%20Press%20Conferences/ICoNETS-2015/Source-Manuscripts/19_L04-Nuryanti_p128-135.docx#_msoanchor_1">[P1]</a>Revised sentence</p></div></div></div>

The techno-economic analysis of a PV system is designed to measure the viability of the designed system from an economical and technological point of view assuming some specific environmental conditions. In this research, for the techno-economic analysis of PV system the authors are focused on four general categories of factors which are highly influential on the investment decision in this field. These are the PV system costs, the electricity cost, the sunlight and other environmental characteristics and the financial incentives. Each of this factors is analyzed in order to understand and evaluate the general conditions that influence the decision in the photovoltaic business. The methodology that is used for explaining the real business environment in PV field and the main indicators that can estimate the investment profitability is the case study related to formal opportunities for developing PV investment projects in Romania. The investors in PV field have to understand the life cycle of a PV system that can give an overlook of the cost reduction opportunities and also make them sensible to the decommissioning phase of such an investment. For future investments in the PV field in Europe the authors identified and analyzed the main factors that characterize the PV business development in the next period.

ABSTRAK ANALISIS KELAYAKAN FINANSIAL PROYEK PLTN SMR DI INDONESIA DENGAN MEMPERTIMBANGKAN VARIABEL KETIDAKPASTIAN. SMR merupakan salah satu alternatif mengatasi ketergantungan wilayah Luar Jawa Bali terhadap PLTD. Masalah yang sangat krusial dalam proyek PLTN (termasuk SMR) adalah finansial, terkait dengan sifat padat modal pada proyek ini. Selain itu, pada proyek PLTN SMR juga dimungkinkan terjadinya beberapa variabel ketidakpastian. Penelitian ini bertujuan untuk melakukan analisis kelayakan finansial proyek PLTN SMR dengan mengakomodasi kemungkinan terjadinya variabel ketidakpastian tersebut. Metodologi yang digunakan adalah analisis probabilistik yang dilakukan dengan teknik Monte Carlo. Teknik ini mensimulasikan keterkaitan antara variabel-variabel ketidakpastian dengan indikator kelayakan finansial proyek. Hasil penelitian menunjukkan bahwa pada pendekatan probabilistik proyek PLTN SMR dinilai layak pada “most probable value” harga jual listrik sebesar 15 cents/kWh, ditunjukkan dengan rata-rata NPV yang positif (US$ 135.324.004) dan rata-rata kedua nilai IRR yang lebih dari MARR (IRR proyek = 10,65%, IRR Equity = 14,29%, sementara MARR = 10%). Probabilitas ditolaknya proyek PLTN SMR adalah sekitar 20%. Tiga variabel utama yang paling berpengaruh dalam proyek adalah: harga jual listrik, biaya investasi dan tingkat inflasi. Kata kunci: kelayakan finansial, PLTN SMR, variabel ketidakpastian, NPV, IRR ABSTRACT FINANCIAL FEASIBILITY ANALYSIS ON SMALL MEDIUM REACTOR NUCLEAR POWER PLANT (SMR NPP) PROJECT IN INDONESIA UNDER UNCERTAINTY. NPP SMR is one alternative to overcome the Outside Java Bali region's dependence on diesel power plant. One crucial issue in the NPP project (including SMR) would be financing, associated with the capital-intensive nature of the project. In addition, the SMR NPP project also be vulnerable in occurrence of some uncertainties. Therefore, this study aimed to analyze the financial feasibility of SMR NPP project by accomadating the possibility of the uncertainties. The methodology used is probabilistic analysis which was performed by Monte Carlo technique. This technique simulates the relationship between the uncertainty variables with financial feasibility indicators. The results showed that in probabilistic approach, SMR NPP project is considered feasible on the "most probable value" of electricity selling price of 15 cents/kWh, indicated by positive average value of NPV (US$ 135,324,004) and the average value of both of IRRs are bigger than MARR (IRR project = 10.65%, IRR Equity = 14.29%, while MARR = 10%). The probability of rejection of the SMR project was about 20%. The three main variables that are most influential in the project were: selling price of electricity, invesment cost and inflation rate.

Containment Integrity

Various studies have shown that hydrogen combustion is one of major risk contributors to threaten the integrity of the containment in a nuclear power plant. That hydrogen risk should be considered in severe accident strategies in current and future NPPs has been emphasized in the latest policies issued by the National Nuclear Safety Administration of China (NNSA). According to a deterministic approach, three typical severe accident sequences for a PWR large dry containment, such as the large break loss-of-coolant (LLOCA), the station blackout (SBO), and the small break loss-of-coolant (SLOCA) are analyzed in this paper with MELCOR code. Hydrogen concentrations in different compartments are observed to evaluate the potential hydrogen risk. The results show that there is a great amount of hydrogen released into the containment, which causes the containment pressure to increase and some potential inconsecutive burnings. Therefore, certain hydrogen management strategies should be considered to reduce the risk to threaten the containment integrity.
