The Hydro-Mechanical Fuel Test Facility (HMFTF) is a large-scale thermal-hydraulic separate effects test facility located in the Advanced Nuclear Systems Engineering Laboratory (ANSEL) at OSU. The facility operates under an NQA-1 compliant quality assurance program and is currently listed on the Idaho National Laboratory Quality Supplier List as a level 1 supplier. The facility is designed such that any element which can fit within the inner vertical height of the test section region may be tested. 

The HMFTF was designed to cover the operating envelope of all high performance research reactors in the US while operating under subcooled conditions. The primary loop is rated to 600 psig and 460°F and has the capability to operate with net flow rates ranging from 100 gpm to 1600 gpm. Operators are able to maintain conditions within ± 5 °F, psig, and gpm during testing. In order to recreate the thermal-hydraulic conditions in reactors, the loop can be configured for up or down-flow through the test section
