Reactor Core and Control
- a.
The reactor core shall approximate a right circular cylinder with an equivalent diameter of about 136 inches and an active height of about 132 inches.*
- b.
The reactor core shall consist of approximately 43,000 Zircaloy-4 clad _fuel rods containing slightly enriched uranium in the form of sintered U02 pellets.
The fuel rods shall be grouped into 204 assemblies.
A core plug or plugs may be used to replace one or more fuel assemblies subject to the analysis of the resulting power distribution.
- c.
The fully loaded core shall contain approximately 211,000 pounds uo2 and approximately 56,000 pounds of Zircaloy-4.
Poison may be placed in the fuel bundles for long-term reactivity control.
- d.
The core excess reactivity shall be controlled by a combination of boric acid chemical shim, cruciform control rods, and mechanically fixed boron rods where required.
Forty-five control rods shall be distrib_uted throughout the core as shown in Figure 3..:5 of the FSAR.
Four of these control rods may consist of part-length absorbers.
- An emergency core cooling system shall be installed consisting of various subsystems each with internal requndancy.
These subsystems shall include four safety *injection tanks, two high-pressure and two low-pressure safety injection pumps and a safety injection and refueling water storage tank.
FUEL STORAGE New Fuel Storage
- a.
The pitch of the new fuel storage rack lattice is +/- 9.375 inches,
_ and every other position in the lattice shall be permanently occupie'd nu0483-0105a-43-46 5-3 Proposed
