Definitions 1.1 1.0 USE AND APPLICATION 1.1 Definitions

---

NOTE---------------------------------------------------

The defined terms of this section appear in capitalized type and are applicable throughout these Trojan Independent Spent Fuel Storage Installation (ISFSI) Technical Specifications and Bases.

Term Definition ACTIONS ACTIONS shall be that part of a Specification that prescribes Required Actions to be taken under designated Conditions within specified Completion Times.

AIR PADS The AIR PADS are commercially available lifting devices that are used to move the CONCRETE CASKS. The AIR PADS consist of four air bladders that are inserted into the CONCRETE CASK air inlets and are inflated to lift a CONCRETE CASK up to four inches off the surface which then allows it to be moved.

CONCRETE CASK The CONCRETE CASK is the structure in which a MULTI-PURPOSE CANISTER (MPC) is stored.

DAMAGED FUEL DAMAGED FUEL ASSEMBLIES are fuel assemblies which can ASSEMBLY be handled by normal means: (1) with known or suspected cladding defects greater than pinhole leaks or hairline cracks; or (2) with missing fuel rods that are not replaced with dummy fuel rods.

Fuel assemblies which cannot be handled by normal means due to fuel cladding damage are considered to be FUEL DEBRIS.

DAMAGED FUEL ASSEMBLIES are stored in FAILED FUEL CANS or DAMAGED FUEL CONTAINERS.

DAMAGED FUEL DAMAGED FUEL CONTAINERS are specially designed CONTAINER enclosures for DAMAGED FUEL ASSEMBLIES and FUEL DEBRIS. DAMAGED FUEL CONTAINERS are stored in an MPC.

FAILED FUEL CAN FAILED FUEL CANS are specially designed enclosures for DAMAGED FUEL ASSEMBLIES, FUEL DEBRIS, and Trojan ISFSI 1.1-1 Renewed License

Definitions 1.1 1.0 USE AND APPLICATION 1.1 Definitions PROCESS CAN CAPSULES. FAILED FUEL CANS are stored in an MPC.

FUEL DEBRIS FUEL DEBRIS is fuel with known or suspected defects, such as ruptured fuel rods, severed rods, or loose fuel pellets and fuel pellet fragments. FUEL DEBRIS includes fuel assembly metal fragments such as portions of fuel rods and grid assemblies. Fuel assemblies which cannot be handled by normal means due to fuel cladding damage are considered to be FUEL DEBRIS. FUEL DEBRIS is stored in PROCESS CAN CAPSULES, which are stored in FAILED FUEL CANS, or directly in FAILED FUEL CANS or DAMAGED FUEL CONTAINERS depending upon the extent of damage.

INTACT FUEL INTACT FUEL ASSEMBLIES are fuel assemblies which can be ASSEMBLY handled by normal means: (1) without known or suspected cladding defects greater than pinhole leaks or hairline cracks; or (2) with missing fuel rods which are replaced by dummy rods. Fuel assemblies from which fuel rods are missing shall not be classified as INTACT FUEL ASSEMBLIES unless dummy fuel rods are used to displace an amount of water equal to or greater than that displaced by the original fuel rod(s).

MULTI-PURPOSE The MPC is the stainless steel welded container that is designed for CANISTER (MPC) storage and transportation of INTACT FUEL ASSEMBLIES and FAILED FUEL CANS and DAMAGED FUEL CONTAINERS that contain DAMAGED FUEL ASSEMBLIES and FUEL DEBRIS.

PROCESS CAN PROCESS CAN CAPSULES are sealed, inerted canisters CAPSULE containing FUEL DEBRIS. PROCESS CAN CAPSULES are stored in FAILED FUEL CANS.

Trojan ISFSI 1.1-2 Renewed License

Definitions 1.1 1.0 USE AND APPLICATION 1.1 Definitions STORAGE OPERATIONS STORAGE OPERATIONS include all licensed activities that are performed at the ISFSI while a CONCRETE CASK containing an MPC with INTACT FUEL ASSEMBLIES, DAMAGED FUEL ASSEMBLIES, or FUEL DEBRIS, is located within the ISFSI perimeter including movement of and use of the TRANSFER CASK or a Transport Cask.

TRANSFER CASK The TRANSFER CASK is used to support an MPC at the TRANSFER STATION.

TRANSFER STATION The TRANSFER STATION is a steel structure, located on the Transfer Pad, to the west of the Storage Pad, designed to safely facilitate loading the MPC into a Transport Cask.

TROJAN STORAGE The TROJAN STORAGE SYSTEM is defined as the TranStorTM SYSTEM CONCRETE CASK containing a Holtec MPC-24E or MPC-24EF.

The Holtec MPC-24E and MPC-24EF used at Trojan are modified to fit within the TranStor CONCRETE CASKS, as described in the Trojan ISFSI Safety Analysis Report.

Logical Connectors 1.2 1.0 USE AND APPLICATION 1.2 Logical Connectors PURPOSE The purpose of this section is to explain the meaning of logical connectors.

Logical connectors are used in Technical Specifications (TS) to discriminate between, and yet connect, discrete Conditions, Required Actions, Completion Times, Surveillances, and Frequencies. The only logical connectors that may appear in TS are AND and OR. The physical arrangement of these connectors constitutes logical conventions with specific meanings.

BACKGROUND Several levels of logic may be used to state Required Actions. These levels are identified by the placement (or nesting) of the logical connectors and by the number assigned to each Required Action. The first level of logic is identified by the first digit of the number assigned to a Required Action and the placement of the logical connector in the first level of nesting (i.e., left justified with the number of the Required Action). The successive levels of logic are identified by additional digits of the Required Action number and by successive indentations of the logical connectors.

When logical connectors are used to state a Condition, Completion Time, Surveillance, or Frequency, only the first level of logic is used, and the logical connector is left justified with the statement of the Completion Time, Surveillance, or Frequency.

EXAMPLES The following example illustrates the use of logical connectors. The only logical connector remaining in these TS is AND.

Trojan ISFSI 1.2-1 Renewed License

Logical Connectors 1.2 1.0 USE AND APPLICATION 1.2 Logical Connectors EXAMPLES EXAMPLE 1.2-1 (continued)

ACTIONS CONDITION REQUIRED ACTION COMPLETION TIME A. LCO not met A.1 Verify....

AND A.2 Restore...

In this example the logical connector AND is used to indicate that when in Condition A, both required Actions A.1, and A.2 must be completed.

Trojan ISFSI 1.2-2 Renewed License

Completion Times 1.3 1.0 USE AND APPLICATION 1.3 Completion Times PURPOSE The purpose of this section is to establish the Completion Time convention and to provide guidance for its use.

BACKGROUND Limiting Conditions for Operations (LCOs) specify the lowest functional capability or performance levels of equipment required for safe operation of the facility. The ACTIONS associated with an LCO state Conditions that typically describe the ways in which the requirements of the LCO can fail to be met. Specified with each stated Condition are Required Action(s) and Completion Time(s).

DESCRIPTION The Completion Time is the amount of time allowed for completing a Required Action. It is referenced to the time of discovery of a situation (e.g., equipment or variable not within limits) that requires entering an ACTIONS Condition unless otherwise specified, providing the facility is in a specified condition stated in the Applicability of the LCO. Required Actions must be completed prior to the expiration of the specified Completion Time. An ACTIONS Condition remains in effect and the Required Actions apply until the Condition no longer exists or the facility is not within the LCO Applicability.

Once a Condition has been entered, subsequent subsystems, components, or variables expressed in the Condition, discovered to be not within limits, will not result in separate entry into the Condition unless specifically stated. The Required Actions of the Condition continue to apply to each additional failure with Completion Times based on initial entry into the Condition.

EXAMPLES The following example illustrates the use of Completion Times.

The only Completion Time remaining in the LCOs is Immediately.

Trojan ISFSI 1.3-1 Renewed License

Completion Times 1.3 1.0 USE AND APPLICATION 1.3 Completion Times EXAMPLES EXAMPLE 1.3-1 (continued)

ACTIONS CONDITION REQUIRED ACTION COMPLETION TIME A. LCO not met. A.1 Restore compliance Immediately with LCO.

When Immediately is used as a Completion Time, the Required Action should be pursued without delay and in a controlled manner.

Trojan ISFSI 1.3-2 Renewed License

Frequency 1.4 1.0 USE AND APPLICATION 1.4 Frequency PURPOSE The purpose of this section is to define the proper use and application of Frequency requirements.

DESCRIPTION Each Surveillance Requirement (SR) has a specified Frequency in which the Surveillance must be met in order to meet the associated Limiting Condition for Operation (LCO). An understanding of the correct application of the specified Frequency is necessary for compliance with the SR.

The "specified Frequency" is referred to throughout this section and each of the Specifications of Section 3.0, Surveillance Requirement (SR)

Applicability. The "specified Frequency" consists of the requirements stated in the Frequency column of each SR.

Situations where a Surveillance could be required (i.e., its Frequency could expire), but where it is not possible or not desired that it be performed until sometime after the associated LCO is within its Applicability, represent potential SR 3.0.4 conflicts. To avoid these conflicts, the SR (i.e., the Surveillance or the Frequency) is stated such that it is only required when it can be and should be performed. With a SR satisfied, SR 3.0.4 imposes no restriction.

Trojan ISFSI 1.4-1 Renewed License

Frequency 1.4 1.0 USE AND APPLICATION 1.4 Frequency EXAMPLES The following examples illustrate the various ways that Frequencies are specified.

EXAMPLE 1.4-1 SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY Verify ambient air temperature within limit. Every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> Example 1.4-1 contains the type of SR most often encountered in the TS.

The Frequency specifies an interval (every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />) during which the associated Surveillance must be performed at least one time. Performance of the Surveillance initiates the subsequent interval. Although the Frequency is stated as every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, an extension of the time interval to 1.25 times the stated Frequency is allowed by SR 3.0.2 for operational flexibility. The measurement of this interval continues at all times, even when the SR is not required to be met per SR 3.0.1 (such as when a variable is outside specified limits, or the facility is outside the Applicability of the LCO). If the interval specified by SR 3.0.2 is exceeded while the facility is in a condition specified in the Applicability of the LCO, the LCO is not met in accordance with SR 3.0.1.

If the interval as specified by SR 3.0.2 is exceeded while the facility is not in a condition specified in the Applicability of the LCO for which performance of the SR is required, the Surveillance must be performed within the Frequency requirements of SR 3.0.2 prior to entry into the specified condition. Failure to do so would result in a violation of SR 3.0.4.

Trojan ISFSI 1.4-2 Renewed License

Frequency 1.4 1.0 USE AND APPLICATION 1.4 Frequency EXAMPLES EXAMPLE 1.4-2 (continued)

SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY Verify ambient air temperature is within Once within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> prior to limits. starting activity AND 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> thereafter Example 1.4-2 has two Frequencies. The first is a one time performance Frequency, and the second is of the type shown in Example 1.4-1. The logical connector AND indicates that both Frequency requirements must be met. Each time the example activity is to be performed, the Surveillance must be performed within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> prior to starting the activity.

The use of once indicates a single performance will satisfy the specified Frequency (assuming no other Frequencies are connected by AND).

This type of Frequency does not qualify for the 25% extension allowed by SR 3.0.2.

Thereafter indicates future performances must be established per SR 3.0.2, but only after a specified condition is first met (i.e., the once performance in this example). If the specified activity is canceled or not performed, the measurement of both intervals stops. New intervals start upon preparing to restart the specified activity.

Programs 5.5 5.0 ADMINISTRATIVE CONTROLS 5.5 Programs The following programs shall be established, implemented, and maintained.

5.5.1 Technical Specifications (TS) Bases Control Program This program provides a means for processing changes to the Bases of these Technical Specifications.

a. Changes to the Bases of the TS shall be made under appropriate administrative controls and reviews.

b. The licensee may make changes to the Bases without prior NRC approval provided the changes do not require prior NRC approval pursuant to 10 CFR 72.48.

c. The Bases Control Program shall contain provisions to ensure that the Bases are maintained consistent with the SAR.

d. Proposed changes that do not meet the criteria of 5.5.1.b above shall be reviewed and approved by the NRC prior to implementation. Changes to the Bases implemented without prior NRC approval shall be provided to the NRC on a frequency consistent with 10 CFR 72.48.

5.5.2 Radioactive Effluent Control Program This program implements the requirements of 10 CFR 72.44 (d).

a. The Trojan ISFSI does not create any radioactive materials or have any radioactive waste treatment systems. Therefore, specific operating procedures for the control of radioactive effluents are not required. The MPC Lid Weld Helium Leak Rate test that was conducted during cask loading provides assurance that there are essentially no measurable radioactive effluents from the ISFSI.

b. This program includes an environmental monitoring program. The environmental monitoring program ensures the annual dose equivalent to any real individual located outside the ISFSI Controlled Area does not exceed regulatory limits.

Programs 5.5 5.0 ADMINISTRATIVE CONTROLS 5.5 Programs 5.5.3 CONCRETE CASK Thermal Monitoring Program This program provides guidance for temperature measurements that are used to monitor the thermal performance of each CONCRETE CASK.

a. The air outlet temperature and the ambient air temperature are measured daily.

The temperature difference between the air outlet temperature and the ambient air temperature will be calculated and recorded. The air inlet vents will be inspected and verified free of blockage weekly. In the event of an environmental phenomenon occurring, the frequency of visual inspection will be increased in accordance with the severity and consequences of the event.

b. If any air outlet temperature or temperature difference between air outlet and ambient temperatures show an unexplained reading, a comparison with predicted and/or baseline data will be performed and appropriate actions taken to determine the cause and return the temperature to an acceptable value. One of the immediate actions will be to increase the frequency of temperature monitoring.

c. If any air outlet temperature reaches or exceeds the program limit, the NRC will be notified in accordance with 10 CFR 72.75(b), (e), and (f), and actions will be taken to evaluate the effects and impact of the high temperature on the CONCRETE CASK. Taking actions when air outlet temperature reaches the program limit should preclude reaching the short term bulk concrete temperature limit which is 350°F. Concrete temperatures in excess of 350°F could potentially weaken the concrete strength and tests may have to be performed to evaluate the concrete and to justify continued use of the CONCRETE CASK.
