F NCSU PULSTAR Technical Specifications i
3.0
- LIMrrING CONDITIONS FOR OPERATION 3.1 Reactor Core Configuration l
Applicability 1
This specification applies to the reactor core configuration during forced convection or natural convection flow operation.
Obiective l
The objective is to assure that the reactor will be operated within the bounds of established Safety Limits.
Specification The reactor shall not be operated unless the following conditions exist:
a.
A maximum of twenty-five fuel assemblies in a five by fiv: array cOnfigurat!On.
l b.
A maximum of ten graphite reflectors @jiljyysXjNi@il Ellis^fjgfisi@
j Ecsiiisbpiiiill6EI6f]hisis located on the core periphery.
l c.
Unoccupied grid plate penetrations plugged.
1 d.
A minimum of four control rod guides are in place.
e.
The maximum worth of a single fuel assembly shall not exceed 1.59%Ak/k (1590 pcm).
Bases Specifications 3.1(a) through 3.1(d) require that the core be configured such that there is no bypass cooling flow around the fuel through the grid plate.
Specification 3.1(c) provides assurance that a fuel loading accident will not result in a Safety Limit to be exceeded as discussed in SAR Section 13.2.2.1.
