_ TMI-1 CYCLE 10 CORE OPERATING LIMITS REPORT REV

SUMMARY

OF CHANGE APPROVAL DATE 1 LOCA 1imits in Figure 7 were reduced by 3-fo ff 1.0 and 1.3 kw/ft at the 2' level for MkB8 and MkB9 fuel, respectively.

Conservative high burnup fuel CMS kw/ft nonitoring limits administrative 1y installed in Table 2 at BOC were replaced with BWFC-recommended fresh fuel limits (adjusted for the 2' level reductions) from 400-661 EFPD.

New references added. ,

TR 099 4 Rev. 1 I Page 1 of 41 ABSTRACT This Core Operating Limits Report (COLR) has been prepared in accordance with the requirements of TMI-l Technical Sp0cification 6.9.5. The core operating ,

limits were generated using the methodologies described in References 12 <

through 31 and were documented in References 1 through 5. The information in this COLR was reviewed for use at TMI-1 in References 6 through 11.

The Full Incore System (FIS) operability requirements contained within describe the number and location of Self-Powered Neutron Detector (SPND) strings that must be operable in order to monitor imbalance and quadrant tilt using the FIS.

Quadrant tilt limits for FIS, out-of-core detector [OCD) system and minimum incore system [ MIS) are given in Table 1.

Table 2 is discussed below with Figure 7.

Rod position limits are provided in Figures 1 to 3 to ensure that the safety criteria for DNBR protection, LOCA kw/ft limits, shutdown margin and ejected rod worth are met.

Imbalance limits for FIS, OCD and MIS are given in Figures 4 to 6.

COLR Figures 1 through 6 may have three distinctly defined regions:

1. Permissible Region

2. Restricted Region

3. Not Allowed Region (Operation in this region is not allowed)

Inadvertent operation within the Restricted Region for a period not exceeding four (4) hours is not considered a violation of a limiting condition for operation. The limiting criteria within the Restricted Region are potential ejected rod worth and ECCS power peaking. Since the probability of these accidents is very low, especially in a four (4) hour time frame, inadvertent operation within the Restricted Region for a period not exceeding four (4) hours is allowed.

COLR Figure 7 indicates the LOCA limited maximum allowable linear heat rates as a function of fuel rod burnup and fuel elevation for Mark B8 and Mark B9 fuel. Bounding values for monitoring these limits for the current cycle in terms of cycle burnup and axial detector levels are listed in Table 2.

COLR Figure 8 provides the Axial Power Imbalance Protective Limits (APIPL) that preserve the DNBR and Centerline Fuel Melt design criteria.

COLR Figure 9 provides the Protection System Maximum Allowable Setpoints for Axial Power Imbalance which combine the power / flow and error-adjusted axial imbalance trip setpoints that ensure the APIPL of Figure 8 are not exceeded.

$ c TR 099 Rev. O Page 2 of 41 Enclosure 1 contains operating limits not required by TS, but monitored by the Process Computer Nuclear Applications Software as part of the bases of the required limits and setpoints. These include the core minimum DNBR and the Maximum Allowable Local Linear Heat Rate Limits.

Enclosure 2 contains the bases descriptions of the Power-to-Flow Trip Setpoint to prevent violation of DNBR criteria and the Design Nuclear Power Peaking Factors for axial flux shape (F 2) and hot channel nuclear enthalpy rise (F NH)

N that define the reference design peaking condition in the core.

1. Core Minimum DNBR Operating Limit

(

Reference:

BAW-2187)

The core minimum DNBR value as measured with the NAS Thermal Hydraulic Package (Display 1 or 4) should not be less than 2.02 (102% ICDNBR).

2. Maximum Allowable Local Linear Heat Rate Limits

(

Reference:

TS 2.1 Bases)

The maximum allowable local linear heat rate limit is the minimum LHR that will cause centerline fuel melt in the rod. This limit is the basis for the imbalance portions of the Axial Power Imbalance Protective Limits and Setpoints in Figures 8 and 9 of the COLR, respectively. The limit is fuel design-specific; the value for the most limiting fuel design in the current core is used for monitoring as given below:

l 1

Reference:

TS 23.1, Table 23-1 an'd 23.1 Bases The nuclear overpower trip setpoint based on RCS flow (power / flow or flux / flow trip).for the current cycle is 1.08. This setpoint applies .

to four , three-and two pump operation as described in TS Table 23-1 and Figure 9 of the COLR.

The power / flow trip, in combination with the axial power imbalance trip, provides steady-state DNB protection for the Axial Power Imbalance Protective Limit (Figure 8).' A reactor trip is initiated when the core power, axial poiver peaking and reactor coolant flow conditions indicate an approach to the DNBR limit. The power / flow trip also provides transient protection for loss of reactor coolant flow events, such as loss-of one RC pump from a four RC pump operating condition.

Power level and reactor flow rate combinations for' four , three- and two-pump operating conditions are as follows:

1. Trip would occur when four reactor coolant pumps are operating if power level is 108 percent and flow rate is 100 -

percent, or power level is 100 percent and flow rate is_92.5 percent.

2. Trip would occur when three reactor coolant pumps are operating if power level is 80.6 percent and flow rate is 74.7 percent or power level is 75 percent and flow rate is 69.4 percent.

3. Trip would occur when one reactor coolant pump is operating in-each loop (total of two pumps operating) if power level is 53.1 percent and flow rate is 49.2 percent or power level is 49 percent and flow rate is 453 percent.

The power level trip and associated reactor power / axial power-imbalance boundaries are reduced by the power-to-flow ratio as a percent (1.08 percent) for each one percent flow reduction.

2. Design Nuclear Power Peaking Factors

(

Reference:

TS 2.1 Bases)

The design nuclear power peaking factors given below define the reference design peaking condition in the core for operation at the maximum overpower.

These peaking factors serve as the basis for the pressure / temperature core protection safety limits and the power-to-flow limit that prevent cladding failure due to DNB overheating.

. Nuclear Enthalpy Rise Hot Channel Factor (Radial-Local Peaking Factor), F",,

F",, = 1.71
