Abstract

This article analyzes the development potential of a Small Modular Reactor (SMR) as a solution energy transition in Indonesia to reduce dependence on fossil fuels, especially oil and coal. Through a literature review, the article compares SMR performance with Generator Electricity Steam Power (PLTU) in terms of energy capacity, impact, and additional applications such as water desalination and hydrogen production. The results showed that the fourth generation SMRs (HTGR, MSR) have high-efficiency electricity, more tall 40-50%, compared to Steam Power Plant (30-40%), with low carbon (3,676-5,388 g CO2 equivalent/kWh for SMR and 1,000 g CO2 /kWh for PLTU). SMR is also capable of producing desalinated water at the lowest cost (USD 0.398/m3 or Rp 6,574/m3) and sustainable hydrogen (9.63 g/kWh). However, adoption of SMR in Indonesia faces complex challenges, including high FOAK costs, regulations that are not yet adaptive, limited supply of special fuels, gaps in skilled human resources, and community resistance regarding waste. Nuclear. This article recommends regulatory revisions, financial incentives based on KPBU schemes, HR training through international collaboration, and public education strategies to increase social acceptance. With integrated policies, SMR has the potential to become a pillar of Indonesia's energy transition towards decarbonization and sustainable energy security.

Abstract

The use of lead-based radiation shielding materials continues to face increasing rejection due to their toxicity, substantial weight, and incompatibility with sustainability principles. Recent research has driven the development of safer and lighter alternative materials that provide radiation attenuation effectiveness comparable to, or even surpassing, that of lead. This review article summarizes advancements in geopolymers, environmentally friendly heavy concrete, and polymer composites enriched with heavy metals as lead-free radiation shielding materials. Lattice vibration interactions, particularly optical phonons, are also discussed due to their growing relevance in enhancing photon-energy absorption in polymer composites. This review is intended to provide a comprehensive overview of emerging trends, underlying mechanisms, and the implementation potential of next-generation alternative radiation shielding materials
