“…Despite this and apparent discrepancies with the Texas TRIGA irradiation studies (Klingberg et al 2013) the observations are in accord with reported and visualized results in Fig. 2 of Steinhauser et al (2012), agreeing fully with the experimental data within the range of uncertainty.…”

“…Regarding sample 7, there is good agreement with Klingberg et al (2013) for the ratio of 133 Xe/ 135 Xe, but the ratio of 133m Xe/ 131m Xe is drawn significantly to the domain of fission generated radioxenon. In addition, both metastable isotopes show lower than expected activities compared to 133 Xe and 135 Xe under the assumption of pure activation.…”

“…By making use of these reported measurements, we estimate here the annual release of 133 Xe. An estimate for the annual release of the other isotopes is achieved by multiplying the annual release of 133 Xe with scaling factors that apply for the isotopic activity ratios after 30 min of activation of air by epithermal neutrons (Klingberg et al 2013). The details of this calculation are as follows.…”

“…In addition, the operational isotopic ratio trajectories are marked for an NPP (Kalinowski et al 2010) and for the TRR (Tayyebi 2017). Finally, the isotopic ratios resulting from activating atmospheric air by thermal and by epithermal neutrons for 30 min, as found in Klingberg et al (2013) are marked for different times of decay after 30 min of irradiation. The highest datum represents no decay.…”

To monitor compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT), the International Monitoring System (IMS) is being established which will include 40 sensor systems for atmospheric xenon radioactivity. Radioactive isotopes of the noble gas xenon provide the most likely observable radioactive signatures of underground nuclear explosions. These isotopes are frequently detected by IMS noble gas systems as a result of normal operational releases from different types of nuclear facilities including nuclear power plants (NPPs), medical isotope production facilities (MIPFs), and nuclear research reactors (NRRs). Improved knowledge of the contribution of different emission sources on IMS observations strengthens the screening of radioxenon measurements to exclude observations not relevant to emissions from a nuclear explosion. The contribution of NPPs and MIPFs to the global radioxenon emission inventory is fairly well understood. NRRs have yet to be systematically assessed. This paper is the first attempt to assess the total emission inventory of NRRs expressed as annual total discharges. The results can enhance understanding of those sources most likely to impact IMS background observations and to guide future studies on contributions to IMS station background.

Radionuclides are monitored in the atmosphere for the signatures of nuclear explosions, as part of the verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Civil nuclear facilities, such as Nuclear Power Plants (NPPs) and Isotope Production Facilities (IPFs) are sources of anthropogenic radionuclides in the atmosphere and these signatures are sometimes indistinguishable to those of a nuclear explosion. In order to improve the understanding of civil radionuclide-emitting facilities and their impact on the International Monitoring System (IMS) of the CTBT, a group of scientists from the UK, US and Sweden are collaborating with EDF Energy UK to measure radionuclide emissions from an Advanced Gas-cooled Reactor (AGR) nuclear power station. Emissions are being measured at the source, via a stack monitor and high-resolution gamma spectrometry measurements of filters and also at tens of kilometres away via three sensitive radioxenon atmospheric samplers. The timing, isotopic composition, activity magnitudes and other release parameters of interest are investigated, to improve the discrimination between a civil radionuclide release and an explosive nuclear test. This paper outlines the work of the Xenon and Environmental Nuclide Analysis at Hartlepool (XENAH) collaboration, describes the equipment fielded and provides initial results from each measurement campaign.
