Gentlemen:

The NRC staff has concluded the review of BWR off-gas systems pertaining to
explosions.  The staff has determined that your system, along with procedures
and/or committed changes, provides reasonable assurance that the potential for
external off-gas explosions is minimized.

The enclosed report, NUREG/CR-0727, "Boiling Water Reactor Off-Gas Systems
Evaluation," prepared by the staff and its consultant, summarizes their
evaluation and is provided for your information.

                                    Sincerely,

                                      for Operating Reactors Projects
