CHAPTER 4
included them in the technical specifications. The applicant has also
justified the technical specifications.
4.5.3 Operating Limits
Areas of Review
In this section of the SAR, the applicant should present the nuclear design features
necessary to ensure safe operation of the reactor core and safe shutdown from any
operating condition. The information should demonstrate a balance between fuel
loading, control rod worths, and number of control rods. The applicant should
discuss and analyze potential accident scenarios, as distinct from normal operation,
in Chapter 13 of the SAR.
The areas of review are discussed in this section of the format and content guide.
Acceptace Criteria
The acceptance criteria for the information operating limits include the following:
* All operational requirements for excess reactivity should be stated,
analyzed, and discussed. These could pertain to at least the following:
- temperature coefficients of reactivity
- fuel burnup between reloads or shutdowns
- void coefficients
- xenon and samarium override
- overall power coefficient of reactivity if not accounted for in the
items listed above
- experiments
i Credible inadvertent insertion of excess reactivity should not damage the
reactor or fuel; this event should be analyzed in Sections 4.5 and 4.6 and
Chapter 13 of the SAR.
* The minimum amount of total control rod reactivity worth to ensure
reactor subcriticality should be stated.
