Enclosure:
As stated cc w/encl: See next page
REQUEST FOR ADDITIONALINFORMATION Although the burnup criteria for storage in Pools C or D willbe implemented by administrative procedures to ensure verified burnup prior to fuel transfer into these pools, an administrative failure should be assumed and evaluation of a fuel assembly misloading event (i.e., a fresh pressurized-water reactor (PWR) assembly inadvertently placed in a location restricted to a burned assembly as per Technical Specifications (TS)
Figure 5.6.1) should be analyzed.
2; How willthe burnup requirements needed to meet TS Figure 5.6.1 be ascertained for fuel assemblies shipped from other PWR plants (Robinson)?
3.
The fuel enrichment tolerance is specified in Section 4.5.2.5 as+0.0/-0.05.
Why isn't a positive tolerance of +0.05 assumed (i.e., 5.0+0.05 weight percent U-235)?
4.
Justify that the allowance that was assumed for possible differences between the fuel vendor and the Holtec calculations is sufficient to also encompass burnup calculational uncertainties.
5.
The summary of criticality safety calculations shown in Tables 4.2.1 and 4.2.2 indicates that the total uncertainty is a statistical combination of the manufacturing tolerances but do not indicate methodology biases and uncertainties.
Were these included?
