The Theory for Designing a Giant Safe Long-Duration Dry Nuclear Battery for Urban-Scale Power Generation & other safe usages; {e.g. named: X-Guardian NuCore} []


This paper presents the conceptual design and feasibility analysis of X-Guardian NuCore, a novel dry nuclear battery engineered for urban-scale electricity generation or other useful safe and peaceful usages. The proposed system integrates advancements in betavoltaic and thermoelectric conversion technologies, smart shielding, and nuclear material miniaturization to enable safe, maintenance-free operation for over 25 years. Designed to power a city of up to 3 million inhabitants, the X-Guardian NuCore model combines theoretical developments with insights from existing technologies such as RTGs, microreactors, and AI-based safety systems. This paper reviews the state of the art, identifies technological gaps, and proposes a unified vision for future implementation(s). The concept is intended as a foundation for prototyping and potential patent development.
