User Need Request regarding PRM-50-93 from NRC's NRR to RES: ML100770117

Mark Edward Leyse summarized the User Need Request in his presentation to the ACRS Subcommittee on Thermal-Hydraulic Phenomena, October 18, 2010.

PRM-50-93 is the subject of a user need request, dated April 26, 2010, from Eric Leeds, Director, Office of Nuclear Reactor Regulation, to Brian Sheron, Director Office of Nuclear Reactor Research. NRR's user need request states that I cite extensive data from numerous multi-rod experiments and that their request is a high priority, with a target date of September 30, 2010.
