Wisconsin Electnc POWER COMPANY Point Beach Nuclear Plant (414) 755-2321 6610 Nuclear Rd.. Two Rivers. WI 54241 NPL 97-0129 10 CFR 50.54(f)

DOCKETS 50-266 AND 50-301 RESPONSE TO NRC BULLETIN 96-01 CO'NTROL ROD TEST DATA FROM UNIT 2 OUTAGE U2R22 POINT BEACil NUCLEAR PLAN f. UNITS 1 AND 2 in accordance with commitments made in our April 3,1996 response to Bulletin 96-01, control rod data from tests conducted in 1996 during our Unit 2 refueling outage are attached. As discussed in our response to the Bulletin, we committed to submit this data within 30 days of completing the last test of each outage. Due to the extension of our U2R22 refueling outage beyond calendar year 1996, we have decided to transmit the 1996 data now, rather than wait for q the completion of our current U2R22 outage.

U2R22 was commenced in Oc*.ober 1996. Completed tests include:

(1) End-of-Cycle (EOC) Rod Drop Testing of Unit 2 rodded fuel assemblies was completed in October 1996. Without exception, the drop time for each control rod was less than the maximum limit of 2.2 seconds established in Technical Specification 15.3.10.It Recoil was evident on all control rods. Test results are enclosed.

(2) EOC Drag Force Tests on Discharged Assemblies from Unit 2 were completed in October 1996. Drag force tests were performed on all rodded assemblies from Unit 2 Cycle 22 during rod unlatching (Unit 2 containment). Test results are enclosed.

Due to the length of our U2R22 outage, Beginning-of-Cycle (BOC) Control Rod Drag Force Testing and BOC Control Rod Drop Tests have not yet been conducted for Unit 2 Cycle 23.

Because these tests will not have been conducted in calendar year 1996, they are not subject to our Bulletin 96-01 commitment to submit test data. Likewise, the commitment to submit a core map of rodded fuel assemblies for Unit 2 Cycle 23 does not apply for 1997 core configurations.
