A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The spatial and temporal evolution of the 3H levels in the water of the River Tagus in its passage through various regions of Spain and Portugal was analysed. Using mathematical time-series techniques, analytical expressions were obtained for the temporal trend and the periodicity present in the data.These expressions were used to determine the transit times between the sampling sites. The results indicated that the mean speed of 3H displacement was 12 km/month. The residence times of tritium in the water were also obtained. They were found to depend on the sampling points, with values ranging between 31 and 77 months. The concentrations of 3H varied cyclically at the six sampling points, with periods of around 24 months upstream of the Almaraz Nuclear Power Plant and about 12 months downstream.
