Latest Patents

Izzo’s patent, “Shielded Access Door for a Nuclear Steam Generator Manway Port,” describes a removable door assembly designed for a port surrounded by a manway flange. A bracket attaches to the flange, while pivoting swing arms support a shield positioned near the port. The arrangement leaves a gap that permits access to the steam generator interior while helping shield against radiation streaming through the port.

The shield includes a ventilation hole that allows air-borne radioactive particles to be exhausted from the generator. A second, spaced-apart shield aligns with the hole and can be positioned between the radiation beam and the opening, reducing the risk of radiation escaping through it. The main shield is made of lightweight, connectable segments to make lifting and positioning the assembly easier.
