FuelSolutions' Storage System Amendment 41.1-2 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 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 Require 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 Condition, Completion Time, Surveillance, or Frequency.
EXAMPLES The following examples illustrate the use of logical connectors.
EXAMPLE 1.2-1 ACTIONS
COMPLETION CONDITION REQUIRED ACTIONTIME 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.
FuelSolutions' Storage System Amendment 41.2-1 Logical Connectors 1.2 1.2 Logical Connectors
EXAMPLES EXAMPLE 1.2-2 (continued) ACTIONS
COMPLETION CONDITION REQUIRED ACTION TIME A. LCO not met A.1 Stop...
OR A.2.1 Verify...
AND A.2.2.1 Reduce...
OR A.2.2.2 Perform...
OR A.3 Remove...
This example represents a more complicated use of logical connectors. Required Actions A.1, A.2, and A.3 are alternative choices, only one of which must be performed as indicated by the use of the logical connector OR and the left justified placement. Any one of these three Actions may be chosen. If A.2 is chosen, then both A.2.1 and A.2.2 must be performed as indicated by the logical connector AND. Required Action A.2.2 is met by performing A.2.2.1 or A.2.2.2. The indented position of the logical connector OR indicates that A.2.2.1 and A.2.2.2 are alternative choices, only one of which must be performed.
FuelSolutions' Storage System Amendment 41.2-2 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 Operation (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.
FuelSolutions' Storage System Amendment 41.3-1 Completion Times 1.3 1.3 Completion Times
EXAMPLES The following examples illustrate the use of Completion Times with different types of Conditions and changing Conditions.
EXAMPLE 1.3-1 ACTIONS COMPLETION CONDITION REQUIRED ACTION TIME B. RequiredB.1 Perform Action12 hours Action and B.1.
associated AND Completion Time not B.2 Perform Action36 hours met. B.2.
Condition B has two Required Actions. Each Required Action has its own separate Completion Time. Each Completion Time is referenced to the time that Condition B is entered.
The Required Actions of Condition B are to complete action B.1 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> AND complete action B.2 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.
A total of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is allowed for completing action B.1 and a total of 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> (not 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />) is allowed for completing action B.2 from the time that condition B was entered.

B. RequiredB.1 Perform Action12 hours Action and B.1.
associated AND Completion Time not B.2 Perform Action36 hours met. B.2.
When it is determined that a system does not meet the LCO, Condition A is entered. If the system is not restored within 7 days, Condition B is also entered and the Completion Time clocks for Required Actions B.1 and B.2 start. If the system is restored after Condition B is entered, Condition A and B are exited, and therefore, the Required Actions of Condition B may be terminated.

The Note above the ACTIONS Table is a method of modifying the Completion Time tracking. If this method of modifying the Completion Time tracking were only applicable to a specific Condition, the Note would appear in that Condition rather than at the top of the ACTIONS Table.
The Note allows Condition A to be entered separately for each component, and Completion Times tracked on a per component basis. When a component does not meet the LCO, Condition A is entered and its Completion Time starts. If it is determined that subsequent components do not meet the LCO, Condition A is entered for each component and separate Completion Times start and are tracked for each component.
IMMEDIATE When Immediately is used as a Completion Time, the COMPLETION TIME Required Action should be pursued without delay and in a controlled manner.
FuelSolutions' Storage System Amendment 41.3-4 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 of the Frequency column of each SR, as well as certain Notes in the Surveillance column that modify performance requirements.
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 an SR satisfied, SR 3.0.4 imposes no restriction.
The use of met or performed in these instances conveys specific meaning. A Surveillance is met only when the acceptance criteria are satisfied. Known failure of the requirements of a Surveillance, even without a Surveillance specifically being performed, constitutes a Surveillance not met.
FuelSolutions' Storage System Amendment 41.4-1 Frequency 1.4 1.4 Frequency
EXAMPLES The following examples illustrate the various ways that Frequencies are specified:
EXAMPLE 1.4-1 SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY Verify pressure within limit. 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> Example 1.4-1 contains the type of SR most often encountered in the Technical Specifications (TS). The Frequency specifies an interval (12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-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 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, an extension of the time interval to 1.25 times the interval specified in the 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 it is determined the equipment does not meet the LCO, a variable is outside specified limits, or the unit is outside the Applicability of the LCO). If the interval specified by SR 3.0.2 is exceeded while the cask 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 unit 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.
FuelSolutions' Storage System Amendment 41.4-2 Frequency 1.4 1.4 Frequency
EXAMPLES EXAMPLE 1.4-2 (continued) SURVEILLANCE REQUIREMENTS
SURVEILLANCE FREQUENCY Verify flow is within limits. Once within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> prior to starting activity AND 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-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 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.

LCO 3.0.6 Not applicable to an SFSS.
LCO 3.0.7 Not applicable to an SFSS.
FuelSolutions' Storage System Amendment 43.0-1 LCO Applicability 3.0 3.0 SURVEILLANCE REQUIREMENT (SR) APPLICABILITY
SR 3.0.1 SRs shall be met during the specified conditions in the Applicability for individual LCOs, unless otherwise stated in the SR. Failure to meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the LCO. Failure to perform a Surveillance within the specified Frequency shall be failure to meet the LCO except as provided in SR 3.0.3. Surveillances do not have to be performed on equipment or variables outside specified limits.
SR 3.0.2 The specified Frequency for each SR is met if the Surveillance is performed within 1.25 times the interval specified in the Frequency, as measured from the previous performance or a measured from the time a specified condition of the Frequency is met.
For Frequencies specified as once, the above interval extension does not apply.
If a Completion Time requires periodic performance on a once per basis, the above Frequency extension applies to each performance after the initial performance.
Exceptions to this Specification are stated in the individual Specifications.
SR 3.0.3 If it is discovered that a Surveillance was not performed within its specified Frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified Frequency, whichever is less. This delay period is permitted to allow performance of the Surveillance.
If the Surveillance is not performed within the delay period, the LCO must immediately be declared not met, and the applicable Condition(s) must be entered.
When the Surveillance is performed within the delay period and the Surveillance is not met, the LCO must immediately be declared not met, and the applicable Condition(s) must be entered.
SR 3.0.4 Entry into a specified condition in the Applicability of an LCO shall not be made unless the LCOs Surveillances have been met within their specified Frequency.
This provision shall not prevent entry into specified conditions in the Applicability that are required to comply with ACTIONS or that are related to the unloading of a CANISTER.

4.2 Storage Pad 4.2.1 Storage Location for Storage Casks Each STORAGE CASK is designed to radiate sufficient heat when placed on the storage pad in the appropriate location. Thermal analyses of normal STORAGE OPERATIONS (Storage System FSAR, Section 4.4) assume that the casks will be stored in an array that places adjacent casks a minimum of 15 feet apart, center-to-center. This minimum spacing is an important parameter to the proper dissipation of radiant heat energy from the cask.
4.2.2 Pad Properties to Limit Cask Gravitational Loadings Due to Postulated Drops 4.2.2.1 Storage Cask The FuelSolutions' W150 STORAGE CASK has been evaluated for an end drop onto a reinforced concrete pad. The evaluations are based on the following parameters:

This evaluation must be performed using the same methodology as described in WSNF-200 FSAR, Section 3.7.5.1.
4.3 Site Specific Parameters and Analyses The minimum site-specific parameters and analyses that will need verification by the system user are:
4.3.1 Fire and Explosion The potential for fire and explosion shall be addressed, based on site-specific considerations.
This includes the condition that the on-site transporter fuel tank will contain no more than 70 gallons of fuel.
For the purpose of providing the licensee with design basis loading criteria for comparison to site-specific hazards, a postulated explosion is taken to be the same as the tornado wind pressure load defined in Section 2.3.4.2 of the Storage System FSAR (WSNF-200).

5.3.1 Cask Sliding Evaluation The FuelSolutions' W150 STORAGE CASK has been evaluated for sliding in the unlikely events of a seismic event. A sliding coefficient of friction of 0.3 is used in these analyses. This program provides a means for evaluating the coefficient of friction to assure that the cask will not slide significantly during the seismic event.
5.3.1.1 Pursuant to 10CFR72.212, this program shall evaluate the site-specific ISFSI pad configurations/conditions to assure that the cask would not slide significantly during the postulated design basis earthquake. The program shall conclude that the surface sliding friction coefficient of friction is greater than or equal to 0.3.
FuelSolutions' Storage System Amendment 45.0-2 Administrative Controls 5.0 5.0 Administrative Controls
5.3.1.2 Alternatively, for site-specific ISFSI pad configuration/conditions with a lower sliding coefficient of friction than 0.3, the program shall evaluate the site-specific conditions to assure that the FuelSolutions' W150 STORAGE CASK will not slide significantly during the postulated design basis earthquake. The program shall also evaluate storm winds, missile impacts and flood forces to assure that the cask will not slide such that it could result in impact with other casks or structures at the ISFSI. The program shall assure that these alternative analyses are documented and controlled.
5.3.2 Cask Transport Evaluation Program This program provides a means for evaluating va rious transport configurations and transport route conditions to assure that the design basis drop limits are met.
5.3.2.1 Pursuant to 10CFR72.212, this program shall evaluate the site-specific transport conditions. To demonstrate compliance with Technical Specification 4.2.2, the program shall conclude that the expected lift height above the transport surface shall be less than or equal to that described by Technical Specification 4.2.2.
Also, the program shall conclude that the transport route conditions (e.g., surface hardness and pad thickness) are equivalent to or less limiting than those prescribed for the typical pad surfaces which form the basis for Technical Specification 4.2.2.
5.3.2.2 Alternatively, for site-specific transport conditions which are not encompassed by those of Technical Specification 4.2.2, the program shall evaluate the site-specific conditions to assure that the STORAGE CASK end-drop loading does not exceed 88.5 g and the TRANSFER CASK side drop loading does not exceed 60 g. This alternative analysis shall be commensurate with the analysis which forms the basis of Technical Specification 4.2.2 (Reference FuelSolutions' Storage System FSAR, Section 3.7). The program shall assure that these alternative analyses are documented and controlled.
5.3.2.3 This program shall establish administrative controls and procedures to assure that cask transport operations are conducted within the limits imposed by the Technical Specification or the alternative analysis described above.
5.3.3 Technical Specifications (TS) Bases Control Program This program provides a means for processing changes to the Bases of these Technical Specifications.
5.3.3.1 Changes to the Bases of the TS shall be made under appropriate administrative controls and reviews.
FuelSolutions' Storage System Amendment 45.0-3 Administrative Controls 5.0 5.0 Administrative Controls
5.3.3.2 Licensees may make changes to Bases without prior NRC approval provided the changes do not involve either of the following:
- A change in the TS incorporated in the license
- A change to the FSAR or Bases that involves an unreviewed safety question, a significant increase in occupational exposure, or a significant unreviewed environmental impact as defined in 10CFR72.48.
5.3.3.3 The Bases Control Program shall contain provisions to ensure that the Bases are maintained consistent with the FSAR.
5.3.3.4 Proposed changes that do not meet the criteria of 5.3.3.2 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 10CFR72.48(b)(2).
5.3.4 Radioactive Effluent Control Program This program implements the requirements of 10CFR72.44(d).
5.3.4.1 The FuelSolutions' Storage System 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. Specification 3.1.3, CANISTER Leak Rate, provides assurance that there are essentially no radioactive effluents from the CANISTERs.
5.3.4.2 This program includes an environmental monitoring program. The FuelSolutions' Storage System may be included in a site environmental monitoring program.
5.3.4.3 An annual report shall be submitted pursuant to 10CFR72.44(d)(3) specifying the quantity of each of the principal radionuclides released to the environment in liquid and in gaseous effluents during th e previous calendar year of operation.
5.3.5 Cask Surface Dose Rate Evaluation Program This program provides a means for ensuri ng that ISFSIs using FuelSolutions' STORAGE CASKS do not violate the requirements of 10CFR72 and 10CFR20 regarding radiation doses and dose rates.
5.3.5.1 As part of its evaluation pursuant to 10CFR72.212, the licensee shall perform an analysis to confirm that the limits of 10CFR20 and 10CFR72.104 will be satisfied under the actual site conditions and configurations considering the planned number of casks to be used and the planned fuel loading conditions.
5.3.5.2 On the basis of the analysis in 5.3.5.1, the licensee shall establish a set of cask surface dose rate limits which are to be applied to FuelSolutions' STORAGE CASKS used at the site. Limits shall establish average gamma-ray and neutron dose rates for:

5.3.5.3 Notwithstanding the limits established in TS 5.3.5.2, the dose rate limits may not exceed the following values:
- 50 mrem/hr on the side.
- 510 mrem/hr at the inlet or outlet vent screen surfaces.
- 50 mrem/hr on the top lid.

The measured average dose rates shall be compared to the limits established in TS 5.3.5.2 or the limits in 5.3.5.3, whichever are lower.
5.3.5.5 If the measured average surface dose rates do not meet the limits of TS 5.3.5.2 or TS 5.3.5.3, whichever are lower, the licensee shall take the following actions:
- Notify the U.S. Nuclear Regulatory Commission (Director of the Office of Nuclear Material Safety and Safeguards) within 30 days.
- Administratively verify that the correct fuel was loaded.
- Perform an analysis to determine that placement of the as-loaded cask at the ISFSI will not cause the ISFSI to exceed the radiation exposure limits of 10CFR20 and 10CFR72.
5.3.5.6 If the analysis in 5.3.5.5 shows that placement of the as-loaded cask at the ISFSI will cause the ISFSI to exceed the radiation exposure limits of 10CFR20 and 10CFR72, the licensee shall remove all fuel assemblies from the cask within 30 days of the time of cask loading.
5.3.5.7 The surface dose rates shall be measured at the following points:
- At least eight readings taken at equal spacing around the outside vertical surface of the STORAGE CASK at approximately 6 feet above the base.
- The inlet or outlet vent screen surfaces.
- At least five readings taken on the top lid, with one reading from the center and the other four taken at equal spacing 30 inches from the center.
5.3.5.8 The average dose rates shall be determined as follows:
In each of the three measurement zones in 5.3.5.7, the sum of the dose rate measurements is divided by the number of measurements to determine the
FuelSolutions' Storage System Amendment 45.0-5 Administrative Controls 5.0 5.0 Administrative Controls
average for that zone. The neutron and gamma-ray dose rates are averaged separately. Uniformly spaced dose rate measurement locations are chosen such that each point in a given zone represents approximately the same surface area.
