Столько полония думаю на Земле не наработано еще... Да и проблема отвода тепла при увеличении размера источника станет нерешаемой.Думаю достаточно очевидно что в ближайшие десятилетия никаких ядерных реакторов в космосе не будет.

Кроме того, реальной потребности нет. Сверхмощных энергоустановок на орбите сейчас нет потому что они не нужны,
Power AvailableIn 2005 Rigid-Panel Stretched Lens Arrays were producing 7 kW per wing. Solar arrays producing 300 W/kg and 300 W/m² from the sun's 1366 W/m² energy near the Earth are available. Entech Inc. hopes to develop 100 kW panels by 2010 and 1 MW panels by 2015
Abstract. The state of the art for currently flying space solar photovoltaic arrays is represented by the followingkey metrics: Areal Power: < 300 W/m2, Specific Power: < 60 W/kg and Operating Voltage: < 200 V. To enable themost ambitious and challenging space missions 10-20 years in the future, each of these performance metrics must beimproved dramatically. Only one future solar array technology has the potential to simultaneously extend all of theseperformance metrics: ultra-light refractive concentrator array technology. Under NASA funding, our team hasrecently developed a near-term rigid-panel concentrator array with the following excellent metrics: Areal Power:> 300 W/m2, Specific Power: > 180 W/kg, and Operating Voltage: > 500 V. More recently, under NASA and NSFfunding, our team has been investigating longer term versions of the same basic technology, and has identified a path tothe following revolutionary metrics: Areal Power: > 600 W/m2, Specific Power: > 1,000 W/kg, Operating Voltage:> 1,000 V. In addition to these breakthrough performance metrics, the cost ($/W) of the far-term ultra-lightconcentrator will be much lower than for competing approaches, the stowed power at launch will be unprecedented atmore than 100 kW/m3, and the array capacity will be extended from the current limit of about 30 kW to 100 kW and,eventually, to multi-MW systems. The paper describes the ultra-light concentrator technology, including thedevelopmental road map to achieve the mission-enabling far-term performance metrics summarized above
