05-18-2017 | On March 22, 2017, Unit 2 implemented the guidance of EGM 11-003, Revision 3, " Enforcement Guidance Memorandum 11-003, Revision 3, Dispositioning Boiling Water Reactor Licensee Noncompliance with Technical Specification Containment Requirements during Operations with a Potential for Draining the Reactor Vessel," dated January 15, 2016. Consistent with EGM 11-003, Revision 3, secondary containment operability was not maintained during Operations with a Potential for Draining the Reactor Vessel ( OPDRV) activities, and Required Actions C.1 and C.2 of Technical Specifications (TS) 3.6.4.1, " Secondary Containment," were not completed. These conditions are being reported in accordance with 10 CFR 50.73(a)(2)(i)(B) as operations prohibited by the plant's TS.
Implementation of EGM 11-003, Revision 3, during the Unit 2 refueling outage was a planned activity. As such, there was no causal evaluation of the event. Consistent with the guidance provided in EGM 11-003, Revision 3, BSEP will submit a license amendment request to adopt Technical Specification Task Force ( TSTF)-542 associated with generic resolution to this issue within 12 months from its approval (i.e., from December 20, 2016). |

Background
Initial Conditions At the time of the event, Unit 2 was in Mode 5 (i.e., Refuel), at zero percent of rated thermal power (RTP).
Reportability Criteria On January 15, 2016, the NRC issued EGM 11-003, Revision 3, which provides generic enforcement discretion to allow implementation of specific interim actions as alternative to full compliance with plant TSs related to secondary containment operability during Mode 5 OPDRV activities. To ensure compliance with EGM 11-003 OPDRV Activities." This procedure, which implements compensatory actions that meet or exceed those specified in EGM 11-003, Revision 3, was implemented on one occasion during the 2017, Unit 2 refueling outage. The following list provides the duration of the period during which EGM 11-003, Revision 3, was implemented (i.e., OPDRV activities were in progress with secondary containment inoperable). Unit 2 was in Mode 5 during this period.
On March 22, 2017, Unit 2 implemented the guidance of EGM 11-003, Revision 3, “Enforcement Guidance Memorandum 11-003, Revision 3, Dispositioning Boiling Water Reactor Licensee Noncompliance with Technical Specification Containment Requirements during Operations with a Potential for Draining the Reactor Vessel,” dated January 15, 2016. Consistent with EGM 11-003, Revision 3, secondary containment [NG] operability was not maintained during Operations with a Potential for Draining the Reactor Vessel (OPDRV) activities, and Required Actions C.1 and C.2 of Technical Specification (TS) 3.6.4.1, “Secondary Containment,” were not completed. This condition is being reported in accordance with 10 CFR 50.73(a)(2)(i)(B) as operations prohibited by the plant's TSs.
6 days, 0 hour0 days <br />0 hours <br />0 weeks <br />0 months <br />, 21 minutes Implementation of EGM 11-003, Revision 3, during the Unit 2 refueling outage was a planned activity. As such, there was no causal evaluation of the event.

3. LER NUMBER
End - 00 A review of LERs for the past three years identified the following previous similar occurrences.
BSEP will submit a license amendment request to adopt Technical Specification Task Force (TSTF)-542 within 12 months from its approval (i.e., from December 20, 2016).
The safety significance of this event is minimal. As discussed in EGM 11-003, Revision 3, enforcement discretion related to secondary containment operability during Mode 5 OPDRV activities is appropriate because the associated interim actions necessary to receive the discretion ensure an adequate level of safety. To ensure compliance with the interim actions specified in the EGM, BSEP developed plant procedure 2SP-15-101. This procedure was implemented for the OPDRV activities during which secondary containment was not operable.
