Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?

IR 1395481:

PANEL 902-28 WITH DOORS THATDO NOTLATCH While performing NRC required NTTF (near term task force) seismic walkdowns, Panel 903-28 was found unlatched per IR 01394831. The FIN Team performed a corrective remedial repair of cabinet door 903-28 and then checked the Unit 2 side, Panel 902-28 (located in the front part of the Aux Electric room at elevation 517'-6"). Panel 902-28 was found in the same condition as U3; namely, the opening device is a push button operated without a handle that requires a key to engage the latches. The FIN Team performed remedial repairs on cabinet door 902-28 in addition to 903-28 on 07/30/12.

Operations was unsuccessful in finding a key for the U2 in addition to the U3 doors.

This IR was generated to document unsecured latches for Unit 2 Panel 902-28.

As an interim measure, the doors have been secured (taped shut) to prevent movement during a seismic event. In addition, a satisfactory "tug test" on the secured doors was performed by two SQUG-qualified engineers. This interim solution is judged to be acceptable and has been accepted by Operations (Shift Manager).

IR 1395498:

DATA AQUISITION CABINET 1 & 2 DOOR DO NOT LATCH While performing NRC required NTTF (near term task force) seismic walkdowns, Panels 903-28 and 902-28 were found unlatched per IRs 01394831 & 01395481 respectively.

An extent of condition walkdown was performed in the Aux Electric room at elevation 517"-6" to see if there are other unsecured panel latches. The "Data Aquisition Cabinet #1 & #2" doors were found in similar conditions as those above; namely, the opening device is a button without a handle that requires a key to engage the latches. There are no other panels/cabinets in the Aux Electric room besides those identified above that have the key operated latches.

This IR was generated to document unsecured latches for Data Aquisition Cabinets #1 & #2. These panels are not safety related and since they are by themselves, they have no spatial seismic interaction issues with other cabinets in the Aux Electric room. Therefore, they are judged to not be a seismic interaction concern.
