h$8hIleYaintee AT'ACHMENT 8 1.3 REACTOR 6policability Applies to the reactor vessel, vessel core and internals, as well as the Reactor Coolant System and components, including associated Emergency Core Cooling Systems.
Objectivei To define those design criteria essential in providing for safe system operation which are not covered in Sections 2 and 3.
Sgtcification A.
Bfactor Core The reactor core shall contain 217 fuel assemblies with each assembly containing 176 rods.
Each fuel rod clad with Zircaloy-4 shall have a nominal active fuel length of 136.7 inches.
The fuel shall have a maximum nominal enrichment of 3.70 weight percent U-235.
3 The core excess reactivity shall be controlled by a combination of boric acid chemical shim, Control Element Assemblies (CEAs) and mechanically fixed non-fuel rods when required.
The non-fuel rods may be fixed alumina-boron carbide, solid metal or open tubes.
There are a total of eighty-one (81) full-length, full-strength CEAs provided.
Forty (40) of these are paired to form twenty (20) dual CEAs.
Seventy-seven (77) CEAs, including all dual CEAs, are trippable.
Four (4) of the CEAs are nontrippable.
