Valves Help Protect Environment in a Radwaste Remediation Project
- By April Murelio -
Flowserve Corporation has announced that it has successfully completed seismic testing for Modified Flowserve Durco and McCANNA valves for multiple radiation waste remediation projects.
Flowserve Durco extended bonnet cartridge plug valves and Flowserve McCANNA top-entry cartridge ball valve designs passed stringent seismic testing on the first attempt. Each valve was cycled 16,000 times with pumped simulant flowing at 150 psig. Seismic tests included a 0-100 hertz resonance search, followed by six random-frequency, independent-excitation triaxial seismic tests with up to three-G acceleration.
“Flowserve is proud of the significant role our valves play in protecting the environment during the nuclear waste remediation process,” said Jim McGeehin, General Manager, Flowserve Flow Control Division—Cookeville Operations. “These successful seismic tests build on the NQA-1 qualification Flowserve has maintained since 2001, and demonstrates our commitment to providing solutions to all facets of the nuclear industry.”
The valves will be used in the remediation of nuclear waste. The waste material is chemically treated and vitrified to fuse the radioactive materials into impermeable glass solids, which can then be stored safely as the isotopes decay and ultimately become harmless.
