Subject:

"roposed Technical Specification Change (License Amendment)-

Neutron Monitorine System Cpr ection Pace Reference 2 proposed revisions to Fe:an 2 Technical Specifications (TS)in support of the planned replacement of the power range portion of the Neutron Monitoring System. Because the Power Range Neutron Monitaring system (PRNM) will include Reactor Coolant System Recirculation Flow.,ignal processing which is currently accomplished using separate hardware, Reference 2 described the need to revise TS to consolidate these functions. This would be accomplished for Control Rod Block Instrumentation by revising TS Tables 3.3.6-1,33.6-2, and 4.3.6-1 to add the Flow Upscale control rod block in the Average Power Range Monitor (APRM) trip functions and to delete the Reactor Coolant System Recirculation Flow Upscale trip.

gh The Inoperative trip is also deleted from the Reactor Coolant System Recirculation Flow trips because this function is included in the APRM Inoperative trip, and the Comparator trip is deleted in accordance with Section 3.2.11 of Reference 3.

However, Reference 2 did not include sheet 2 of Table 3.3.6-2 (TS page 3/4 3-44a) to delete the Reactor Coolant System Recirculation Flow trip functions. Therefore, a mark-up copy of this sheet and a retyped version are provided with this letter
