These Limitations are consistent vich the initial conditions assumed for the boron dilucion incidanc in cha accident analyses.

The-boron concentration requirement of specification 3.9.l.b has been conservatively increased co 2400 ppm to agree vith the minimum concentzation of che RUST.
Tha OPERABILITY of the source range neutron flux monitors ensures that redundant monitoring capability is available to datecc changes in the reactivity condition of tha core.
The miIMasm requirement for reactor subc icicaLicy prior co'movemenc of irradiated fuel assemblies in the reactor pressure vessel ensures chat sufficient time has elapsed to allov che radioactive decay of the short Lived fission products.
