1.1 Purpose This Surveillance
Instruction (SI)provides detailed steps for ensuring proper calibrationofthe power range neutron flux channels.1.2 Scope 1.2.1 SurveillanceTesttobe Performed This Instruction
performs a comparison
between the power level calculatedbythe Nuclear Instrumentation
System (NIS)power range neutron flux channelsandthe"true" powerlevelas determinedbya secondary system heat balance based value.If necessary, the power range channels are adjusted to agree withthe"true" power level.This instruction
also verifies availability
of Leading Edge Flow Meter (LEFM)calorimetric
power.1.2.2 Requirements

A.Applicable
Mode-1 (above 15 percent power).8.Performance
Mode-1 (above 15 percent power).1.3 Frequency and Conditions
This test must be performed at leastonceevery24
hours when the reactor power level is greater than 15 percent.[C.3]To ensure NIS accuracy, this test should be performed when directed by 0-80-4 or 0-80-5.Inthe event that the Plant Computer is unavailable, provisions
have been incorporatedinthis proceduretofulfilltheSR
requirements.
