1.0 INTRODUCTION
1.1 Purpose This procedure verifies compliance with Banked Position Withdrawal Sequence (BPWS). This is to ensure the assumptions of the control rod drop accident analyses are satisfied.
1.2 Scope This procedure is performed in conformance with requirements specified in Technical Specification (TS) Surveillance Requirement (SR) 3.1.6.1.
1.3 Frequency This procedure is to be performed once every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
1.4 Conditions This procedure can be performed in Modes 1 thru 4.
1.5 Applicability Modes 1 and 2 with THERMAL POWER d 10% RTP (SR-3.1.6.1).
