Dutch radiopharmaceutical producer Nuclear Research and Consultancy Group (NRG) has begun the regulatory approval process to build a nuclear reactor to replace its High Flux Reactor (HFR) in Petten, Netherlands.
NRG this week submitted an application for an environmental impact assessment report to the Dutch Ministry of Housing, Spatial Planning, and the Environment for the Pallas reactor.
The submission is the first step in a process to request a permit for the construction of a new research reactor to produce isotopes for medical applications and expand scientific and applied nuclear research.
NRG is considering two locations for Pallas: Petten in the northwest region of North Holland and Borssele in the southwest region of Zeeland.
The goal is to have Pallas operating in 2016, pending funding and regulatory approvals.

![Overview of the study design. (A) The fully automated deep learning framework was developed to estimate body composition (BC) (defined as subcutaneous adipose tissue [SAT] in liters; visceral adipose tissue [VAT] in liters; skeletal muscle [SM] in liters; SM fat fraction [SMFF] as a percentage; and intramuscular adipose tissue [IMAT] in deciliters) from MRI. The fully automated framework comprised one model (model 1) to quantify different BC measures (SAT, VAT, SM, SMFF, and IMAT) as three-dimensional (3D) measures from whole-body MRI scans. The second model (model 2) was trained to identify standardized anatomic landmarks along the craniocaudal body axis (z coordinate field), which allowed for subdividing the whole-body measures into different subregions typically examined on clinical routine MRI scans (chest, abdomen, and pelvis). (B) BC was quantified from whole-body MRI in over 66,000 individuals from two large population-based cohort studies, the UK Biobank (UKB) (36,317 individuals) and the German National Cohort (NAKO) (30,291 individuals). Bar graphs show age distribution by sex and cohort. BMI = body mass index. (C) After the performance assessment of the fully automated framework, the change in BC measures, distributions, and profiles across age decades were investigated. Age-, sex-, and height-adjusted body composition reference curves were calculated and made publicly available in a web-based z-score calculator (https://circ-ml.github.io).](https://img.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/05/body-comp.XgAjTfPj1W.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
