Development of a driftless thermometer to improve safety and efficiency in the nuclear power industry

Metrosol Limited是一家老牌的高精度温度计量产品制造商，将与NPL(国家物理实验室)合作开发一种基于约翰逊噪声的新型温度计。这种温度计将是无漂移的，因此将改进核电站温度的测量。温度测量对这些核电站的安全运行至关重要，因此这项技术将有助于在未来继续提供安全的核电。它还将使核电站能够在更高的温度下安全运行，这将提高效率。最初的目标是将能效提高3.3%，这将相应地降低核能发电的成本，并取代更高的碳源。按照英国政府目前计划的发电结构，效率的提高将使碳排放量每天减少4100吨(公吨)，或在反应堆的整个寿命内减少6000万吨。

Metrosol Limited, an established manufacturer of high precision temperature metrology products, will collaborate with NPL (the National Physical Laboratory) in the development of a novel type of thermometer based on Johnson Noise. This thermometer will be driftless and as such will improve the measurement of temperature in nuclear power plants. The measurement of temperature is crucial to the safe operation of these plants so this technology will assist in continuing to provide safe nuclear power in the future. It will also enable nuclear power plants to operate safely at higher temperatures, which will improve efficiency. An initial target is to improve efficiency by 3.3% , which would reduce the cost of electricity generated by nuclear by the corresponding amount and also displace higher carbon sources. With the current generating mix planned by the UK government, the efficiency improvement would reduce carbon emissions by 4,100t (metric tonnes) per day or 60 million tonnes over the life of the reactors.
