Required Response (3) of NRC Bulletin 96-01 stated, in part, "Within 30 days after completing Requested Action (3) for each outage, submit a report that summarizes the data and that documents the results obtained; this is also applicable to Requested Action (4) when any abnormal rod behavior is observed."
Requested Action (3) stated, in part, " Measure and evaluate at each outage of sufficient duration during calendar year 1996, the control rod drop times and rod recoil for all contiel rods. If appropriate plant conditions exist where the vessel head is removed, measure and evaluate drag forces for all rodded fuel assemblies."

s Requested Ac: ion (4) stated, in part, "For each reactor trip during calendar year 1996, verify
, that all control rods have promptly fully inserted (bottomed) and obtain other available 1
information to assess the operability and any performance trend of the rods. In the event that all rods do not fully insert promptly, conduct tests to measure and evaluate rod drop times and rod recoil."
On September 19,1996, at approximately 00:40 hours, Zion Unit 2 was tripped from 0%
power to begin refueling outage Z2R14. When the reactor was tripped, one rod, N-5, indicated 118 steps withdrawn; all other rods indicated full insertion. Investigation found that the signal conditioning module for Rod Position Indicator (RPI) N-5 had failed. The control rod for position N-5 was verified to be fully inserted, and the RPI for N-5 was repaired.
To meet Requested Actions (3) and (4) of NRC Bulletin 96-01, Zion Station performed the applicable sections of Technical Staff Surveillance (TSS) 15.6.57, " Rod Position Indication Calibration and Rod Drop Timing Surveillance," on September 21,1996, at the end of Unit 2 Cycle 14, prior to refueling. All rods had acceptable rod drop times and exhibited normal recoil. Included in Attachment I are the rod drop times for the Unit 2 beginning and end of Cycle 14 tests. In addition, rod drag forces were measured prior to unlatching control rods from their drive shafts in accordance with Fuel Handling Instruction (FHI)-26, " Full Length Control Rod Drive Unlatching Tool." No drag force was measured to be outside of the forty (40) pound acceptance criterion (reference 3). Included in Attachment 2 are the drag test results.
The fuel assembly with the highest burnup (H8 at the center of the core,47,651 MWD /MTU) had a slightly increased drop time. T1 time from loss of stationary gripper coil voltage to entry to dashpot was 14% higher than the time measured at the beginning of the cycle, but still within acceptable bounds. Drag testing on this assembly resulted in a maximum net drag force of only 15 pounds for the approximately ten feet over which the Rod Cluster Control Assembly (RCCA) was withdrawn and reinserted.
