| Summary/Abstract |
This article provides an independent cost estimate for uranium production from seawater through the braid-type adsorbent recovery system proposed by the Japan Atomic Energy Agency (JAEA). Production costs were developed with standard engineering cost estimation techniques using vendor data and plant design and operational data. The analysis includes life cycle discounted cash flows, economies of scale, and propagation of uncertainties. A reference case based on the Japan Atomic Energy Agency assessment, with a fresh adsorbent capacity of 2 kgU/t ads and 6 recycles, yielded a production cost of $1230/kg uranium with a 95 percent confidence interval of [$1030/kg U, $1430/kg U] when component cost uncertainties alone were considered. Sensitivity studies confirmed that adsorbent capacity, number of recycles, and capacity degradation are major cost drivers. If capacity and number of recycles increases to 6 kg U/t ads and 20, respectively, with no degradation and unchanged adsorbent production costs, the uranium production cost drops to $299/kg U.

| Summary/Abstract |
Non nuclear Danish nuclear policy is at a crossroads. Looking back, Denmark's relationship to nuclear technology has been a difficult balancing act for successive governments, trying to soothe an anti-nuclear domestic sentiment on one side and the membership of a nuclear military alliance on the other. This history produced an enduring double approach to nuclear policy by Copenhagen throughout the cold war. Looking ahead, this history is of particular relevance as Denmark and Greenland are considering lifting their twenty-five-year ban on mining radioactive elements and allowing the production of Greenland's uranium. With Greenland's large reserves potentially catapulting this otherwise non-nuclear and non-mining kingdom into one of the world's top suppliers of uranium, the policy debate has to include a look back at Denmark's relationship to nuclear technology, for both peaceful and military purposes.
