LOOP UNCERTAINTY CALCULATION Loop Number: TE-4931A 01 I Page 2 of 22 Originator: BOWERS WW lDate: 04/22/04 l Rev: A Reviewer: CUTLER KE Date: 04/22/04 Approver: WEIDMAN MD Date: 04/22/04 1.0 PURPOSE This section includes the Objective, Limitations, Conclusions, and the Applicability Statement of this calculation.

1.1 Objective The purpose of this calculation is to use the Analytic limit (AL) to determine the Allowable Value (AV), Nominal Trip Setpoint (NTSP) and Actual Trip Setpoint (ATSP) for an increasing temperature signal as sensed by channel "A" of PBAPS Unit 2 Main Steam Line Tunnel Exhaust Duct High Temperature Instruments, TE-4931A and TIS-80547A under normal environmental conditions. The Allowable Value is based on a model of the main steam tunnel as documented in calculation PM-1063. The results of this calculation will be used to support a license amendment request that raises the allowable value in the Technical Specifications. Once the change in Technical Specifications is approved, this calculation forms the basis for the plant setpoint change.

A summary of the calculation results may be found in Section 7.0 of this calculation.

Other redundant/mirror loops for which the results of this calculation are applicable may be found in Section 1.4, Applicability.

1.2 Limitations This calculation is produced utilizing normal environmental conditions and does not account for any accident scenarios.

(See Section 2.2.5).

The appropriate use of this calculation to support design or station activities, other than those specified in Section 1.1 of this calculation, is the responsibility of the user.

1.3 Conclusions Revision 3 of this calculation was issued to change the nominal trip setpoint from 195 degrees F to 225 degrees F. This was accomplished by using a new analytic limit developed in calculation PM-1063.

Since this revision applies only to the main steam line tunnel instruments in the reactor building, the main steam line area temperature instruments in the turbine building were removed from this calculation; a new calculation with TE-4932A as the base was performed for the turbine building instruments.

LOOP UNCERTAINTY CALCULATION Loop Number: TE-4931A 01 I Page 3 of 22 Originator: BOWERS WW IDate: 04/22/04 l Rev: A Reviewer: CUTLER KE Date: 04/22/04 Approver: WEIDMAN MD Date: 04/22/04 Revision 2 of this calculation was issued to change the trip setpoint from 192 to 195 deg F. Refer to ECR 03-00418 for implementation of this setpoint change.

Revision 1 of this calculation was issued to replace the existing indicators with GE NUMAC devices.

This calculation was initially generated as a result of Mod P00105 to separate the Unit 2 and Unit 3 Steam Leak Detection Loops.

1.4 Applicability A data evaluation has been performed to determine which redundant/mirror instrument loops are bound by the results of this calculation (the "base" calculation). The data evaluation results validate that this "base" calculation is applicable to the following Loop Affiliation Numbers:

+ TE-4931A Configuration 01

• TE-4931B Configuration 01

• TE-4931C Configuration 01

• TE-4931D Configuration 01 The results of this "base" calculation are bounding values for the instrument loops listed above based on such factors as instrument manufacturer and model number, instrument location, environmental parameters, and actual installation and use of the instrument in the measurement of the process variable. The redundant/mirror loops are the same manufacturer and model number, are installed the same, and are located in the same environment as the base loop. This calculation is therefore valid for the redundant/mirror loops listed.

2.0 DESIGN BASIS This section includes the Technical Background and Design Input information relevant to this calculation.

2.1 Technical Background High temperature in the space in which the main steam lines are located outside the primary containment could indicate a breach in a main steam line. The automatic closure of various Group I isolation valves prevents the excessive loss of reactor coolant and the release of significant amounts of radioactive material from the nuclear system process barrier. When high temperatures occur in the main steam line space, the following lines are isolated:

a. All four main steam lines.

b. Main steam line drain.

c. Reactor water sample line.

d. Main steam sample line.

The main steam line space high temperature trip is set far enough above the temperature expected during operations at rated power to avoid spurious isolation, yet low enough to provide early indication of a steam line break (Ref. 4.1).

Temperature monitoring instrumentation is provided in the main steam line tunnel exhaust duct and along the steam line in the turbine building to detect leaks in these areas.

Trips are provided on this instrumentation and, when exceeded, cause closure of isolation valves. For large breaks, the high steam flow instrumentation is a backup to the temperature instrumentation (Ref. 4.2).

2.2 Design Input 2.2.1 The main steam line space high temperature setpoint must be set far enough above the temperature expected during operations at rated power to avoid spurious isolation, yet low enough to provide early indication of a steam line break (Ref. 4.1). Calculation PM-1063 determined that the analytic limit for this instrumentation loop is 240 degrees F. Calculation PM-1063 also determined that the maximum temperature upon loss of HVAC is 220 degrees F.

2.2.2 This calculation includes any applicable System Rerate Design/Operating Conditions and Impacts as a result of power rerate analyses per the guidelines contained in Revision 1 of Specification NE-00163.

2.2.3 The delta between the Allowable Value and the Actual Trip Set Point within this calculation is 5 degrees F.

This meets or exceeds the IISCP Program Guidance of greater than one times the Loop Leave Alone Zone (LAZ) (Ref. 4.3) 2.2.4 Based on engineering judgment, Sl has been included as additional margin. This consideration results in a conservatively rounded Allowable Value.

2.2.5 This loop will perform its design function in the early seconds of an accident (Ref. 4.11), the environmental conditions in the area surrounding the loop components will not significantly change in this brief time. Consequently, the environmental conditions for an accident condition will not affect either the output of the loop or each of the individual components. Therefore, this calculation is produced utilizing normal environmental conditions.

The remaining additional margin is "unassigned margin" which represents additional conservatism that may be utilized in future analyses.

2.2.7 All other design inputs to this calculation are documented on the Supporting Data Sheet Attachments.
