Dear Dr. Koch:
Thank you for your letter of April 4,1986 addressed to Chairman Palladino, describing the recent tests at EBR-II demonstrating the inherent reactor shutdown and decay heat removal characteristics of that design.
The NRC staff is aware of the testing at EBR-II and will make appropriate use of the
'information provided by the EBR-II test program.
I am sure that these tests will contribute significantly to the evaluation of the performance capabili-ties of advanced liquid metal reactors.
It may interest you to know that there is presently consideration of developing performance-based regulations, for which tests, such as those recently performed in EBR-II, could serve as a basis.
The Commission's proposed policy on advanced reactors encourages a performance-based approach to the licensing of advanced reactors.
The staff has, in fact, recently received a request from a major reactor vendor to consider a rulemaking to allow certification of a reactor design by test.
Thank you again for your letter sharing your observations on the EBR-II tests.
Please be assured of our interest in such tests and in your comments.
Sincerely, ORIDINAL SIONED BY Themis P. Speis, Director Division of Safety Review & Oversight Office of Nuclear Reactor Regulation
