Annulus Gap Snakes

Annulus Gap Snakes

Annulus gaps snakes are designed to sit or be wedged into the gap created between the canister and transfer cask. T-Flex® snakes are wedged shaped to ensure the fit snuggly into the gap without falling all the way down. Due to the properties of T-Flex®, a plant can expect dose reduction not just with gamma radiation, but also with neutron radiation. These snakes are also covered in fire blanket material to handle the high temperatures associated with dry cask operations.

Lead Wool Snakes

These high density lead wool snakes easily placed into the annulus gaps and provide good gamma attenuation. The lead wool allows for the snakes to easily bend and be packed down if need be. Each snake is coved in high temperature alpha maritex material. Both these and the T-Flex® snakes are built to order with sizes, weights, handles, and grommets all to the specifications of the plant.
