NUREG-1537, Part 2 - NRC

Acceptance Criteria
REAcToR CooLANr SYSTEM
The acceptance criteria for the information on the nitrogen-16 control system
include the'following:
* The reduction in personnel exposure to nitrogen-16 should be consistent
with the nitrogen-16 analyses in Chapter 11 ofthe SAR. Total dose shall
bnot exceed the requirements of 10 CFR Part 20 and should be consistent
- with the fLcility ALARA program.
* System design should not
'-, ,decrease cooling efficiency so that any limiting safety system setting
,would be'exceeded
- lead to uncontrolled release or loss of coolant if a malfunction were
to occur
- prevent safe reactor shutdown and removal of decay heat sufficient
to avoid fuel damage
* The applicant should identify operational limits, design parameters, and
surveillances to be included in the techhical specifications.
Review Procedures
The reviewer should evaluate the design bases and functional requirements of the
system designed to control personnel exposures to nitrogen-16 by
* confirming the amount of nitrogen-I 6 predicted by the SAR analysis at the
proposed power level and the potential personnel exposure rates, including
exposures from direct radiation and airborne nitrogen-16
* reviewing the type of system and the decrease in exposure rates
* reviewing the effect of the proposed system on the full range of normal
reactor operations
* reviewing the possible effects of malfunctions of the nitrogen-16 control'
system on reactor sfety, safe'reacitr shutdowni,'and release of
contaminated primary coolant
