ATTACHMENT 3-5A APPENDIX R EVALUATION REPORT - THREE MILE ISLAND UNIT 1 COMPONENT AVAILABILITY FOR A FIRE IN FIRE AREA/ZONE SHEET 1a LEGEND X - Component Not Available D

- Design Modification Note 1:

Spurious opening of MU-V-16A and 16B during fire in CB-FA-1, -2a, -2d, -2f, FH-FZ-1 and MU-V-16C and 16D during a fire in CB-FA-2b, -2c, -2e, -2g, -3b, FH-FZ-5 due to spurious ESAS initiation can be mitigated by tripping the operating makeup pump(s) (if not required for seal injection) or by manually closing the respective valves after opening MU-V-36 and MU-V-37.

S - Support Not Available RSD - Remote Shut Down P - Available-Cable Protected O

- Open Switch or Breaker M - Available-Manual Operation R

- Repair A - Manual Op. Due to Loss of Inst. Air F

- One or the other is available T

- Trip 3 RC Pumps (Both A loop pumps & either B loop pump)

Note 2:

MU-P-1B is a swing pump normally aligned to 1E 4160V switchgear, but can be transferred to 1D 4160V switchgear. MU-P-1B will be shutdown if 1E 4160V bus is de-energized (e.g. LOOP) and cannot be started without action outside of the control room.

Note 3:

MU-P-1B manual action refers to action to select pump for ES at 1E 4160V switchgear within one hour if a loss of offsite power occurs.

Note 4:

Spurious closure of MU-V-36 due to a fire in AB-FZ-6, CB-FA-1, -2a, -2d, -2f, and MU-V-37 due to a fire in AB-FZ-6, CB-FA-2c, -2e, -2g, -3b due to an inadvertent ESAS actuation may require that these valves be manually opened to support minimum MU pump recirculation in HPI valves are closed.

Note 5:

Air is not required to place the valve in the FSSD position (closed).

- Design Modification Note 1:

Design modification is made of one of the two RC vent valves in series (i.e. RC-V-28 and -44; RC-V-40A and -41A; RC-V-40B and -41B; RC-V-42 and -43) to prevent spurious opening due to any one hot short. However, opening of both valves in any one path does not prevent the plant from safely shutting down and therefore is acceptable.
