A device for passively converting nuclear radiation to electricity comprising a plurality of thin-film flexible solar panels, sandwiched between a plurality of diagnostic intensifying screens by which conversion of radiation to light and subsequently to electrical current through the sandwiched thin-film flexible solar panels is effected. The layered array will be comprised of one layer of intensifying screen material affixed to one layer of thin-film flexible solar panels with repeated layers for a total of three intensifying screen-solar panel pairs. This device makes use of new flexible solar panel design and efficiencies. Through the flexible nature provided by both components (intensifying screen and thin film solar panels), facilitates the complete wrapped envelopment of High Level Nuclear Waste containment cylinders and can accommodate any size and shape requirements.
