Docket No. 50-20 cc: See next page November 30, 2007 Dr. John A. Bernard, Director Nuclear Reactor Laboratory Massachusetts Institute of Technology 138 Albany Street Cambridge, MA 02139-4296
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION, RE: LICENSE RENEWAL (TAC NO. MA6084)
Dear Dr. Bernard:
We are continuing our review of your July 8, 1999 application, and associated supplements, for the renewal of the Massachusetts Institute of Technology's (MIT) Research Reactor Amended Facility Operating License No. R-37. MIT's January 29, 2004, response to an NRC request for additional information (RAI) made the following statements:
Response 33.a) "Process uncertainty is addressed by selecting initial conditions that correspond to the LSSS instead of the normal operational values or even the scram values. This was not done originally for all safety analyses but, as a result of other questions in this series, it has now been done." Response 78. "All transient calculations in Chapter 13 (loss of primary flow, ramp reactivity insertion, step reactivity insertion) have been redone using primary coolant flow of 1800 gpm, which is the LSSS." Please provide copies of the following:
- 1) Each of the redone Chapter 13 calculations and supporting documentation.
- 2) The dose calculations for the MHA analysis, including the dispersion analysis and supporting documentation.
In accordance with 10 CFR 50.30(b), your response must be executed in a signed original under oath or affirmation.
Sincerely,
/RA/ Marvin Mendonca, Senior Project Manager Research and Test Reactors Branch B Division of Policy and Rulemaking Office of Nuclear Reactor Regulation Massachusetts Institute of Technology Docket No. 50-20 cc: City Manager City Hall Cambridge, MA 02139 Department of Environmental Protection One Winter Street Boston, MA 02108 Director Radiation Control Program Department of Public Health 90 Washington Street Dorchester, MA 02121
