While instrumental in meeting global energy demands, nuclear power necessitates vigilant management of its resultant waste. One such byproduct, Strontium-90 (Sr90), poses a distinct challenge when dispersed underground.The VIDARR detector is a technology adapted from the T2K ND280 Electromagnetic calorimeter into an anti-neutrino detector. Anti-neutrinos are subatomic particles emitted during beta decay, including the decay of Sr90. Their unique property is their ability to traverse vast amounts of matter, including dense rock and soil, without interaction, making them ideal for remote detection methodologies.Working with Sellafield Ltd, we propose to utilise this property by detecting and monitoring the anti-neutrinos emanating from Sr90. This presents a deviation from traditional methods, often involving invasive and sometimes costly procedures. With VIDARR, there's potential for non-invasive monitoring.Such advancements are helpful in the broader context of environmental protection and sustainable nuclear energy practices. Effective monitoring of Sr90, even when embedded deep underground, equips us with the capability to pre-emptively identify and address potential environmental hazards.

核电虽然有助于满足全球能源需求，但也需要对其产生的废物进行警惕的管理。其中一种副产品 Strontium-90 (Sr90) 在分散到地下时会带来明显的挑战。VIDARR 探测器是一项从 T2K ND280 电磁量热计改造为反中微子探测器的技术。反中微子是在 β 衰变（包括 Sr90 衰变）过程中释放出的亚原子粒子。它们独特的特性是能够在不相互作用的情况下穿越大量物质，包括致密的岩石和土壤，这使它们成为远程探测方法的理想选择。我们与 Sellafield Ltd 合作，建议通过探测和监测 Sr90 发出的反中微子来利用这一特性。这与传统方法存在偏差，通常涉及侵入性且有时成本高昂的程序。有了 VIDARR，就有了非侵入式监测的潜力。这些进步有助于更广泛的环境保护和可持续核能实践。即使 Sr90 埋藏在地下深处，对 Sr90 的有效监测也使我们能够先发制人地识别和解决潜在的环境危害。
