GEORGE RT Date: 11/20/09 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 determine the Allowable Value (AV),
Nominal Trip Setpoint (NTSP) and Actual Trip Setpoint (ATSP) for a high differential temperature steam source isolation by the Leak Detection System at the Limerick Generating Station (LGS).
The increasing differential temperature signal is sensed by channel "B" of the High Pressure Coolant Injection (HPCI)
Compartment Leak Detection Instrument, TE-055-1N028B &
TE-055-1N029B.
This calculations is performed utilizing environmental conditions for a High Energy Line Break (HELB) accident scenario.
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 The Max and Min Acceptable Limits calculated in Section 7.8 are not authorized for use in the PECo maintenance program by this revision of the calculation.
This calculation is produced utilizing the harsh environmental conditions for a HELB accident scenario.
(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 The Upper Allowable Value of 108.5 DEGF was calculated by the software.
The Upper Allowable Value is the result displayed in Section 7.7 of this calculation.
A Lower Allowable Value of 99.5 DEGF was determined using the calculation results and engineering judgement.
The calculation produces an Upper Allowable Value of 108.5 DEGF.
The Upper Allowable Value (108.5 DEGF) is subtracted from the Upper Analytical/Process Limit (113 DEGF) to obtain a value of 4.5 DEGF which represents a two (2) sigma one sided Loop Uncertainty which does not contain any instrument

Date: 11/17/09 A prover: GEORGE RT Date: 11/20/09 drift.
This amount (4.5 DEGF) is then added to the Lower Analytical/Process Limit of 95 DEGF to obtain the 99.5 DEGF value (Lower Allowable Value).
An analysis of the proposed changes to the current station process setpoint values in relation to the results of this calculation has been performed and it has been concluded that the results of this calculation support the proposed changes to the current station setpoint values (Ref 4.15).
An Insulation Resistance (IR) Calculation for TE-055-1N028B Configuration 01 determined that the IR error associated with this instrument loop was insignificant
(< 0.001% of loop span).
It was therefore concluded that no IR effects would be included in this calculation.
This IR Calculation resides in the IISCP software and is utilized as further justification for the position taken by PECo previously that IR concerns do not have any adverse effects on system operability at LGS.
The environmental conditions for the locations of the temperature elements for the redundant/mirror loops are the same/equivalent or not as harsh as those specified for the temperature element for this loop.
Since the variables in this calculation are the same/equivalent or more restrictive, this calculation is valid for the redundant/mirror loops listed in Section 1.4.
1.4 Applicability A data evaluation has been performed in order to determine
- which, if any, 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-055-1N028D Configuration 01 TE-055-1N029D TE-055-2N028B Configuration 01 TE-055-2N029B TE-055-2N028D Configuration 01 TE-055-2N029D 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 only difference among the three redundant/mirror loops is the difference in environmental data for each loop due to the physical locations of each thermocouple, which does not introduce any additional uncertainty.

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 HPCI steam lines are located outside the primary containment could indicate a breach in a HPCI steam line.
The automatic closure of the HPCI isolation valve prevents the excessive loss of reactor coolant and the release of significant amounts of radio-active material from the nuclear system process barrier.
When high temperatures occur in the HPCI steam line space, the inboard and outboard steam supply isolation valves are isolated.
Pairs of temperature elements monitor for high ventilation air differential temperature and compartment ambient temperature.
One sensor of each pair is associated with one of the logic divisions; the other is associated with the other division.
2.2 Design Input 2.2.1 Calculation -1001 specifies 113.0 DEGF as the Upper Analytical/Process Limit (AL) and 95.0 DEGF as the Lower Analytical/Process Limit (AL)
(Ref 4.11).
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 Specification NE-177 (Ref 4.6 & 4.8).
2.2.3 Additional margin of 4.5 DEGF was added to this calculation to support the setpoint recommended by Calculation -1001.
Of this 4.5 DEGF, 4.5 DEGF is assigned margin to support the IISCP Loop Leave Alone Zone (LAZ)guidelines as discussed in Section 2.2.6 and to account for the calibration practices of the instrument channels.
The calibration practices of the instrument channels are accounted for by providing additional margin for M&TE beyond that in Section 6.2.2.
This is done to provide 1% to account for the setting tolerance of the TIS.
This also provides additional margin beyond that portion allocated in Section 6.2.1 to cover the 1% required accuracy for the TE.
Setting Tolerance is not provided specifically for the TE since it is not calibratable.
2.2.4 Based on engineering judgement, Sl has been included as a process consideration.
This consideration results in a conservatively rounded Allowable Value that supports the current Tech Spec revision request.
2.2.5 The selection of HELB environmental conditions for the performance of this calculation is based on engineering judgement and system knowledge.
The environmental conditions for a HELB accident

Date: 11/17/09 Approver: GEORGE RT Date: 11/20/09 scenario are the most severe conditions to which the thermocouple sensors may be exposed and still be expected to perform their safety function.
2.2.6 The delta between the Allowable Value and the Actual Trip Set Point within this calculation is 4.5 DEGF which meets or exceeds the IISCP Program Guidance of greater than one times the LAZ (Ref 4.3) 2.2.7 The Setting Tolerances for the TIS in this calculation were reallocated from the region between AL and AV to the region between NTSP and ATSP in order to obtain the target Tech Spec setpoint.
This reallocation was accomplished by assigning 0.0 to the Setting Tolerance of each instrument and verifying that the assigned margin amount was greater than one LAZ.
Since the LAZ is equal to the square root of the sum of the squares of the Setting Tolerances, verification that the assigned margin is greater than one LAZ insures that the effects of the Setting Tolerances are included in the determination of the ATSP.
No specific setting tolerance was provided for the T/C since it is not calibratable.
2.2.8 All other design inputs to this calculation are documented on the Supporting Data Sheet Attachments.
