SEABROOK STATION TECHNICAL REQUIREMENTS Chapter 1 - Introduction
1.0 INTRODUCTION
The implementation of the Seabrook Station Technical Specification Improvement Program has resulted in certain "Technical Requirements" being removed from the Technical Specifications and incorporated in this manual.
The Technical Requirements and changes to them shall be reviewed, approved, and issued in accordance with the instructions in the Regulatory Compliance Manual (NARC) Chapter 6, Section 1.0.
The Technical Requirements (TR) maintained a format and language similar to the Technical Specifications (TS) as a matter of convenience. In many instances, however, the TRs require functionality of a structure, system, or component (SSC), rather than operability of the SSCs.
Functionality is an attribute of SSCs that is not controlled by the TS. An SSC is functional or has functionality when it is capable of performing its specified function, as set forth in the current licensing basis. Functionality does not apply to specified safety functions, but does apply to the ability of non-TS SSCs to perform other specified functions that have a necessary support function. The TRs use the term operable only in reference to a TS-controlled attribute of an SSC.
Defined terms are shown in all capital letters in the TRs. The definitions contained in section 1.0, Definitions, of the TS apply to these terms (excluding the term FUNCTIONAL, which is defined in the preceding paragraph).
Noncompliance with a Technical Requirement or Technical Requirement Program/Procedure will require action dependent upon the relationship to the Technical Specifications. For those Technical Requirements that maintain a corresponding Technical Specification the action shall be that required by the corresponding Technical Specification. For those Technical Requirements that do not have a corresponding Technical Specification, the noncompliance constitutes a degraded or nonconforming condition that requires corrective action in accordance with Appendix B of 10 CFR 50 to correct or resolve the condition. EN-AA-203-1001, Operability Determinations/Functionality Assessments, provides guidance on the appropriate actions for a failure to conform to a current licensing basis function described in the UFSAR. In addition, station procedures initiate a timely risk assessment following a loss of functionality of equipment contained in the PRA model.
When a TRM action requires an evaluation in accordance with the corrective action program, a condition report is initiated to document the failure to meet a Technical Requirement limiting condition for operation. Then, Engineering evaluates the reported condition within 30 days in accordance with PI-AA-104-1000, Condition Reporting. The evaluation determines if the nonconforming condition should be restored to its current design, repaired to an alternate design, or accepted as-is. A work order is initiated when the evaluation determines the condition should be restored to its current design. When the evaluation determines the condition will be restored to an alternate design or accepted for use as-is, Engineering will develop a design change. An evaluation is not required for non-compliance with a Technical Requirement limiting condition for operation resulting from surveillance testing or planned maintenance activities. These scheduled activities are managed under Maintenance Rule (a)(4) Risk Assessment (10 CFR 50.65).
1-1.1 SSTR Rev. 158
A Surveillance Requirement associated with a Technical Requirement may be considered met if the surveillance is performed within 1.25 times the stated surveillance interval. This 25%
extension facilitates surveillance scheduling and considers plant operating conditions that may not be suitable for conducting the surveillance test. This provision applies only to the surveillance requirements in Chapter 2 of this manual excluding (1) those controlled by the TS, and (2) the surveillance requirements specifically excluded in the individual Technical Requirements. Other programs, such as the Containment Leakage Rate Testing Program contain testing requirements and frequencies in accordance with the regulations. This 25% extension cannot be used to extend a test interval specified in the regulations. Further, this provision does not apply to the initial performance of surveillance test, but only to periodic surveillance tests that follow initial performance. The 25% extension is not intended to be used repeatedly merely as an operational convenience to extend surveillance intervals, other than those consistent with refueling intervals, beyond those specified.

LIMITING CONDITION FOR OPERATION TR3-3.3.3.8 The Loose-Part Detection System shall be FUNCTIONAL.
APPLICABILITY: MODES 1 and 2.
ACTION:
As determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program. An evaluation is not required if the noncompliance is a consequence of surveillance testing or planned maintenance.
SURVEILLANCE REQUIREMENTS TR3-4.3.3.8 Each channel of the Loose-Part Detection Systems shall be demonstrated FUNCTIONAL by performance of:
- a. A CHANNEL CHECK on each active channel at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />,
- b. A CHANNEL FUNCTIONAL TEST on each active channel at least once per 31 days, and
- c. A CHANNEL CALIBRATION at least once per 18 months.
ADDITIONAL INFORMATION UFSAR Section 4.4.6.4 describes the Loose Parts Monitoring System (LPMS) and provides a comparison of the LPMS with each of the regulatory positions of Regulatory Guide 1.133, Rev. 1, "Loose-Part Detection Program for the Primary System of Light-Water Cooled Reactors." The loose parts monitoring system provides for the early detection of a loose part within the Reactor Coolant System (RCS) and the acquisition of data to aid plant personnel to determine the significance of the alert signal and the potential safety significance if a loose part is shown to be present.
The Loose Parts Monitoring System consists of sixteen sensor channels to detect loose part impacts in the vicinity of six natural collection regions where a loose part is expected to situate itself in the reactor coolant system. These channels provide audible capability, alert alarms and input into a data acquisition system capable of digitally archiving sensor waveforms for the alarming channel and its three nearest neighbors. Upon alarm, the system defaults to recording and displaying the alarming channel as well as the three nearest channels. The system is capable of immediate visual and audio monitoring of all signals.
2-3.1 SSTR Rev. 127
Technical Requirement 3 Loose-Part Detection System (Sheet 2 of 2)
Data acquisition is normally acquired by automatic actuation when the LPMS alarm is received; however, the data acquisition system is capable of being manually started. Thus, the ability to record data is available whether the data acquisition system is actuated automatically or manually.
With a Loose Parts Monitoring System (LPMS) alarm present (i.e., pre-determined alert level exceeded),
diagnostic steps are required to be taken within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to determine whether a loose part is present and to determine its safety significance. To perform the diagnosis, the capability must exist to view sensor signal data and evaluate present and past data for trends. It should be noted that exceeding an alert level cannot be construed that a loose part is present since other events such as Control Rod movement, flow noise and electronic spikes can momentarily cause an alarm condition.

Technical Requirement 6 Containment Isolation Valves (Sheet 11 of 11)
Administrative Control Requirements for Opening of Locked or Sealed Closed Containment Isolation Valves The opening of locked or sealed closed Containment Isolation Valves on an intermittent basis under administrative control includes the following considerations pursuant to USNRC Generic Letter 91-08:
(1) Stationing an operator, who is in constant communication with the Control Room, at the valve controls, (2) Instructing this operator to close these valve(s) in an accident situation, and (3) Assuring that environmental conditions will not preclude access to close the valves and that this action will prevent the release of radioactivity outside the containment.
The residual heat removal (RHR) suction valves, RC-V23 and RC-V88, may be opened under administrative control to support operation of the RHR system in Mode 4. Because these valves are normally operated from the control room, either of the two required licensed operators in the control room may be credited as the operator required for administrative control to close the valves under accident conditions as directed by procedures.
If the above administrative control requirements are maintained during opening of a locked or sealed closed containment isolation valve, entry into the ACTION statement of Technical Specification 3.6.3 is not required.
NOTE In addition to the containment isolation valves having an
- in this table, all vents, drains, test connections and instrument isolation valves which are located outside containment (e.g., acceptable environmental conditions), but within the outside containment isolation boundary may be opened on an intermittent basis under administrative control without entry into the ACTION statement of Technical Specification 3.6.3.

Technical Requirement 7 Fire Suppression Water System (Sheet 4 of 5)
ADDITIONAL INFORMATION Technical Requirement 7 deals with functionality of the fire suppression water system (fire protection system). The limiting condition for operation TR7-3.7.9.1.c describes functionality in terms of available flow paths capable of distribution to those branches required by TRs 8, 9, and 10. If the flow path is incapable of delivering the required flow of fire water to any spray or sprinkler system, fire hose station, or yard fire hydrant required to be FUNCTIONAL by TR 8, 9, or 10, action b requires establishing a backup Fire Suppression Water System for the affected spray or sprinkler system, fire hose station, or yard fire hydrant within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. A functional flow path also requires that the sectionalizing control and isolation valves are functional as demonstrated by periodic surveillance tests that cycle each valve through one complete cycle of full travel. Post indicator isolation valves are provided at strategic locations in the underground loop header to allow for sectionalization during maintenance and repair, and to provide flow from the pumping facilities in either of two different directions in the event of a line break. Post indicator valves are also positioned in the loop header to isolate the loop between the take-offs for primary suppression and secondary systems. As a result, with a sectionalizing control or isolation valve nonfunctional and open, action c requires verification that capability exists to isolate the portion of the fire header normally isolated by the nonfunctional valve and to maintain availability of the remaining portions (non-isolated sections) of the fire header. If this capability no longer exists such that a break in the fire header could result in a non-isolable leak or a complete loss of the fire water headers, then the action requires establishing a backup fire suppression system within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
In the event a valve becomes nonfunctional and renders the flow path incapable of delivering the required flow to any spray or sprinkler system, fire hose station, or yard fire hydrant required to be FUNCTIONAL by TR 8, 9, or 10, action b is applicable. However, if the nonfunctional valve remains open and does not adversely affect the flow path, the valve should be restored to functional status in a time frame determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program.
The surveillance requirement of TR7-4.7.9.1.1.c is to verify that the valves are in the correct position.
Therefore, a valve whose "normal" position is open but at the time of the surveillance is administratively controlled (tagged) closed, would have to be closed to be in the "correct" position at the time of the surveillance.
When a valve under administrative control (valve tagging order) is moved from its "normal" position to a different position, this different position (open or closed) becomes the "correct" position of the valve due to the tagging order. Prior to the issuance of a tagging order, an evaluation should be performed to determine the impact on the system of that tagging order and any required actions that would have to be taken due to the order.
2-7.4 SSTR Rev. 147
Technical Requirement 7 Fire Suppression Water System (Sheet 5 of 5)
Fire Tank Supply The system is designed with separate but not independent tanks and share some common flow paths.
The water supply for the fire protection system is stored in two 500,000-gallon tanks. 300,000 gallons in each tank is reserved exclusively for fire protection by means of vertical standpipes. This standpipe extends up to the 300,000-gallon level in each tank and provides a source of water for non-fire protection service. The Technical Requirement minimum volume of water in each tank is 215,000 gallons.
The suction piping to the three fire pumps is arranged to permit suction from either or both of the two fire water storage tanks. The manual valves in the suction piping to the fire pumps and in the relief valve header permit isolation of either storage tank.
The fire tanks are not train redundant water supplies. Two tanks are provided so that the minimum required water supply will be available if one of the tanks is nonfunctional.
There is the capability to isolate the water tanks from each other and maintain the water supply to the fire pumps. Placing a tank out of service does not cause any of the fire pumps to become nonfunctional.
As written in the Safety Evaluation Report it is acceptable for the fire pumps to take suction from both water storage tanks. Isolation valves provide the capability to separate the tanks.
Battery Charger The purpose of the battery charger is to maintain the batteries functional. The surveillance verifies the batteries are functional every 7 days thus indirectly verifying the charger is functioning properly. A non-functioning charger does not directly cause the diesel fire pump to become nonfunctional.
Fire Pump Sequential Start Testing The purpose of the sequential start test is to verify the functionality of the system design. The three fire pumps are designed so the electric motor driven fire pump starts at 127 psig decreasing with the time delay relay set at minimal delay. The first diesel driven pump will start at 127 psig decreasing with a ten-second-time delay and the second diesel driven pump will start at 127 psig decreasing with a twenty-second-time delay.
The pumps shall be tested by verifying: (1) that the start pressure switch generates a start signal at a pressure greater than or equal to 125 psig, (2) the time delay relay generates a start signal after the appropriate delay and (3) the pump starts and restores the fire suppression water system pressure greater than or equal to 125 psig.
Fire Pump Surveillance For surveillances or minor maintenance activities that remove a fire pump(s) from service, either ENTER TR7-3.7.9.1 action a or personnel shall remain in the vicinity of the pump(s) available to quickly restore the pump(s) to a FUNCTIONAL status in the event of a fire. If personnel remain in the vicinity and the pump(s) is able to be immediately restored, TR entry is not required.

Technical Requirement 11 Fire Rated Assemblies (Sheet 1 of 7)
LIMITING CONDITION FOR OPERATION TR11-3.7.9.5 All fire rated assemblies (walls, floor/ceilings, cable tray enclosures, and other fire barriers) separating safety-related fire areas or separating portions of redundant systems important to safe shutdown within a fire area and all sealing devices in fire rated assembly penetrations (fire doors, fire windows, fire dampers, cable, piping, and ventilation duct penetration seals) shall be FUNCTIONAL.
APPLICABILITY: When equipment protected by the fire rated assemblies is required to be OPERABLE.
ACTION:
With one or more of the above required fire rated assemblies and/or sealing devices nonfunctional, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> either:
- a. Establish a continuous fire watch on at least one side of the affected assembly, or
- b. Verify the FUNCTIONALITY of fire detectors on at least one side of the nonfunctional assembly and establish an hourly fire watch patrol.
NOTE HOURLY is defined as "being performed within the clock hour."
CAUTION: Management oversight should be exercised to ensure the intent of the requirement to perform patrols hourly is not undermined. For example, although meeting the above definition, it would not be within the intent of this requirement to perform a patrol of an area at one minute before the hour and one minute after the hour to satisfy a 2-hour period.
SURVEILLANCE REQUIREMENTS TR11-4.7.9.5.1 At least once per 18 months the above required fire rated assemblies and penetration sealing devices shall be verified FUNCTIONAL by performing a visual inspection of:
- a. the exposed surfaces of each accessible fire rated assembly,*
The containment and containment enclosure structures are exempt from this surveillance requirement. These structures are surveilled pursuant to Technical Specification Surveillance Requirement 4.6.1.2.
2-11.1 SSTR Rev. 106
Technical Requirement 11 Fire Rated Assemblies (Sheet 2 of 7)
SURVEILLANCE REQUIREMENTS TR11-4.7.9.5.1 (continued)
- b. at least 10% of the accessible fire dampers and associated hardware. If a fire damper is found to be nonfunctional, a visual inspection of an additional 10% sample shall be made.
This inspection shall continue until a 10% sample with no nonfunctional fire dampers is found, or until 100% of the accessible fire dampers are inspected. Samples shall be selected such that each accessible fire damper will be inspected every 15 years.#
- c. at least 10% of each type of accessible sealed penetration. If an apparent change in appearance or abnormal degradation is found that causes the seal to be nonfunctional, a visual inspection of an additional 10% of that type of sealed penetration shall be made.
This inspection shall continue until a 10% sample with no apparent change in appearance or abnormal degradation is found that causes the seal to be nonfunctional, or until 100%
of the accessible seals of that type are inspected. Samples shall be selected such that each accessible penetration will be inspected every 15 years.#
NOTE TYPE is synonymous with category.
If the "tamper seal" is broken, then the fitting cover must be removed and fire seal inspected. The sole purpose of the "tamper seal" is to provide an indication of the fire seal condition without removing the fitting cover. A broken "tamper seal" does not cause the fire seal to be nonfunctional.
TR11-4.7.9.5.2 Each of the above required fire doors shall be verified FUNCTIONAL by inspecting the automatic hold-open, release and closing mechanism and latches at least once per 6 months, and by verifying:**
- a. The FUNCTIONALITY of the fire door supervision system for each electrically supervised fire door by performing a TRIP ACTUATING DEVICE OPERATIONAL TEST at least once per 31 days.
- b. That each locked closed fire door is closed at least once per 7 days.
25% surveillance interval extension is not applicable to 15 year frequency.
The containment air locks are exempt from this surveillance requirement. They are surveilled pursuant to Technical Specification Surveillance Requirement 4.6.1.3.
2-11.2 SSTR Rev. 106
Technical Requirement 11 Fire Rated Assemblies (Sheet 3 of 7)
SURVEILLANCE REQUIREMENTS TR11-4.7.9.5.2 (continued)
- c. That doors with automatic hold-open and release mechanisms are free of obstructions at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and a functional test is performed at least once per 18 months, and

ADDITIONAL INFORMATION
- 1. Verification of Functionality Verification of functionality, when required by an ACTION statement, does not require the performance of the Surveillance Requirements for the affected equipment, if the Surveillance Requirements are current. To verify FUNCTIONALITY of equipment, the action required is to review the appropriate logs to ensure that the equipment has not been declared nonfunctional and ensure that no conditions exist which could render the affected equipment nonfunctional (i.e. power is available, etc.).
- 2. Inspection of Exposed Surfaces of Fire Rated Assemblies Technical Requirement Surveillance Requirement TR11-4.7.9.5.1a requires a visual inspection of the exposed surfaces of each Technical Requirement fire rated assembly. The types of fire rated assemblies inspected under this requirement are concrete and steel walls, ceilings, floors, fire-wrapped conduits and steel beams/columns with fireproofing. Inspection of these fire rated assembly surfaces every 18 months using a hand-over-hand inspection technique is clearly onerous and beyond the intent of the requirement. Such an inspection would be severely labor intensive requiring major scaffolding evolutions, ladder usage and rappelling. Hand-over-hand inspections using scaffolding, ladders and rappelling greatly increase the potential for personnel injury.
2-11.3 SSTR Rev. 106
Technical Requirement 11 Fire Rated Assemblies (Sheet 4 of 7)
ADDITIONAL INFORMATION (continued)
A reasonable visual inspection of the above fire rated assemblies can be accomplished from the floor. Such an inspection may necessitate the use of visual aids such as temporary lighting and binoculars. Precedent currently exists for the performance of inspections from the floor. For example, DRR 92-061 states that a visual inspection of Pyrocrete coated surfaces from the floor, with binoculars if necessary, will provide a reasonable assurance of functionality. The general inspection of the Containment/Containment Enclosure accessible surfaces prior to Type A Integrated Leak Rate Tests has also been performed from the floor using visual aids. This inspection is performed in accordance with the Containment Leakage Rate Testing Program.
Concrete and steel surfaces are unquestionably less susceptible to inadvertent damage than are fireproofed or wrapped surfaces. The design and work controls in place will ensure that penetrations in concrete or steel fire rated assemblies are strictly controlled. If a fire rated assembly is degraded by the performance of a work order or modification, the required compensatory measures would be implemented. A baseline inspection of conduits which require fire seals was conducted by FPLE Seabrook (ref. 93WR2796) to ensure that all conduits which require a seal are actually sealed. This baseline inspection for the presence of conduit seals was also effective in identifying fire rated assembly surfaces that are degraded.
Floor inspections, using visual aids such as temporary lighting or binoculars, if necessary, will provide an acceptable visual inspection in lieu of a hand-over-hand technique. If the inspection from the floor indicates that the fire rated assembly may be degraded it will become necessary to perform a close inspection to evaluate the condition of the barrier.
Undoubtedly, the floor inspections will not be able to cover certain blind-spots on the fire rated assembly surfaces. For example, a section of a wall may not be visible due to the presence of a large ductwork running through/along the wall. In such cases where a blind spot may exist, it is reasonable to conclude that the baseline inspections discussed above provide sufficient evidence to conclude that the fire rated assembly surface is satisfactory. There is no credible mechanism for the wall to become damaged in this blind spot area such that fire barrier would not function.
Certain fire barriers are located in posted/locked high radiation areas. Fire barriers which are located in posted/locked radiation areas, such as Demin. Alley (PAB elev. 7'), may be considered temporarily or permanently inaccessible. Inspections should be coordinated with other activities which are required to be performed in the area. The Health Physics Department should be contacted to establish the practicality of coordination of the barrier inspection with other locked high radiation area entries in accordance with FPLE Seabrook ALARA policies. If it is determined that inspection of the fire barriers cannot be coordinated with other activities in the locked high radiation area, ALARA considerations should be the deciding factor in whether the barrier is inspected or considered temporarily or permanently inaccessible. The Maintenance Manager and/or Station Director should review and approve fire barrier inspections which are waived due to ALARA considerations.
2-11.4 SSTR Rev. 106
Technical Requirement 11 Fire Rated Assemblies (Sheet 5 of 7)
ADDITIONAL INFORMATION (continued)
Penetration seals may be deemed inaccessible if their inspection would necessitate the breaching of a fire barrier such as fire wrap, the movement of seismic supports, the breaching of an equipment qualification barrier, exposure to a high personnel safety risk or if the inspection would be inconsistent with FPLE Seabrook ALARA policies. Specific examples of these conditions are (1) the removal of a metal cover which has an equipment qualification function; (2) the removal of a metal cover which can only be removed by eliminating obstructions such as piping or pipe supports; (3) the removal of fire wrap; or (4) a high personnel safety risk (to be determined by the Plant Manager or Operations Manager). Penetration seals which are not conveniently inspected (e.g., those which require the erection of staging) may not be deemed inaccessible based on inconvenience only. Penetration seals which are temporarily inaccessible may be postponed but must be inspected at a later date. Penetration seals which are located in locked high radiation areas, such as Demin. Alley (PAB elev. 7'), may be considered temporarily inaccessible to allow the inspection to be coordinated with other activities which are required to be performed in the locked high radiation area.
For penetration seals which are deemed inaccessible based on the criteria discussed above, the following procedure and documentation thereof on the applicable surveillance will satisfy the visual inspection requirement of Technical Requirement 11-4.7.9.5.1c:
- 1) Review penetration seal installation documentation and inspection documentation for correct sealant material, seal depth and QA acceptance. Determine if the penetration seal has been reworked and review rework documentation for the same attributes (material, depth, QA), and
- 2) Inspect the fire barrier, EQ barrier or obstructing piping or pipe supports to ensure they are intact. If these items are not intact, the penetration seal must be visually inspected.
- 3. Degraded Fire Doors/Penetration Seals/Fire Rated Assembly Surfaces Technical Requirement Surveillance Requirement TR11-4.7.9.5.2 specifies the surveillance requirements for fire doors. If a surveillance is being performed on a fire door and the door is determined to be nonfunctional, the fire door surveillance must be deemed unsatisfactory and the ACTION requirements of Technical Requirement 11 applied. On occasion, concurrent surveillances are performed on a fire door(s) and on the surfaces of the wall through which the door(s) penetrates. Assuming separate tests are being performed for the doors and the wall surfaces, a failure of the door test does not require a failure of the wall test and conversely a failure of the wall test does not require a failure of the door test. A failure of either test for the door or the wall would require entry into the ACTION requirements of Technical Requirement 11.
If, during a fire barrier inspection, a fire door is incidentally discovered to be degraded, the Work Order is the appropriate mechanism for documenting/correcting the degradation and initiating entry into the ACTION requirements of Technical Requirement 11.
2-11.5 SSTR Rev. 106
Technical Requirement 11 Fire Rated Assemblies (Sheet 6 of 7)
ADDITIONAL INFORMATION (continued)
As identified in TR11-4.7.9.5.1, the Containment and Containment Enclosure structures are exempt from the 18 month surveillance frequency for all fire rated assemblies (walls, floor/ceilings, cable tray enclosures, and other fire rated barriers). It is identified in TR11-4.7.9.5.1 that these structures are surveilled pursuant to Technical Specification Surveillance Requirement 4.6.1.2. This exemption from the 18 month surveillance frequency was approved as a result of Technical Requirements Change Request (CR) 94-01 dated 01/07/94.
The exemption of the Containment and Containment Enclosure from the requirements of TR11-4.7.9.5.1 was justified on the following basis:
- 1) The Integrated Leakage Rate Test (ILRT) visual inspection procedure (EX1803.004) has the same inspection characteristics and general acceptance criteria.
- 2) The robust design of the Containment and Containment Enclosure structures exceeds the requirements for an Appendix R fire barrier.
- 3) The design, work control process and structure integrity requirements will ensure that the integrity of these structures is not compromised.
The containment equipment hatch and personnel hatch doors are considered fire doors as a result of their function but are exempt from the surveillance requirements outlined in Technical Requirement Surveillance Requirement 11-4.7.9.5. The design of the air locks in conjunction with the testing requirements specified in the Containment Leakage Rate Testing Program is adequate to satisfy the inspection requirements of Technical Requirement 11-4.7.9.5.2 for these doors. The intent of the Technical Requirement inspection of the fire doors is to verify that the doors are functional. The testing requirements of the Containment Leakage Rate Testing Program provide reasonable assurance that the air lock doors are operable and the integrity of the fire barrier will be maintained. Failure of the air lock leakage test will not be cause to declare the air lock a nonfunctional fire barrier provided that one of the air lock doors is closed. Technical Specification 3.6.1.3, Action (a) 1 and 2 will ensure that the integrity of this fire barrier is maintained.
Technical Requirement Surveillance Requirement TR11-4.7.9.5.1c specifies the surveillance requirements for penetration fire seals. If a surveillance is being performed on a penetration seal and the seal is determined to be degraded, the penetration seal surveillance must be deemed unsatisfactory and the ACTION requirements of Technical Requirement 11 applied. On occasion, concurrent surveillances are performed on penetration fire seals and on the surfaces of the wall containing the sealed penetration. Assuming separate tests are being performed for the penetration fire seals and the wall surfaces, a failure of the penetration fire seal test does not require a failure of the wall test and conversely a failure of the wall test does not require a failure of the penetration fire seal test. A failure of either the test for the penetration fire seal or the wall would require entry into the ACTION requirements of Technical Requirement 11.
2-11.6 SSTR Rev. 106
Technical Requirement 11 Fire Rated Assemblies (Sheet 7 of 7)
ADDITIONAL INFORMATION (continued)
If, during a fire barrier inspection or at any other time, a penetration seal is incidentally discovered to be missing, the Condition Report is the appropriate mechanism for documenting the degradation and initiating entry into the ACTION requirements of Technical Requirement 11.
Technical Requirement Surveillance Requirement TR11-4.7.9.5.1a requires a visual inspection of the exposed surfaces of each fire rated assembly. The types of fire rated assemblies inspected under this requirement are concrete and steel walls, ceilings, floors, fire-wrapped conduits and steel beams/columns with fireproofing.
If, during a fire rated assembly inspection, a breach in the assembly is identified and verified to be under the scope of the work control process and the ACTION requirements of Technical Requirement 11 have been entered, it is not necessary to fail the fire rated assembly test due to the existence of this breach. Assuming the remainder of the fire rated assembly is satisfactory, the test can be deemed satisfactory in spite of the known/planned breach. It is recommended that the surveillance be annotated to state that the breach was identified and verified to be under the scope of the work control process and the ACTION requirements of Technical Requirement 11 have been entered. If the breach cannot be verified to be under the scope of the work control process and the ACTION requirements of Technical Requirement 11 have not been entered, the Condition Report is the appropriate mechanism for documenting the degradation and initiating entry into the ACTION requirements of Technical Requirement 11.

- f. With any fire detection control panel(s) unable to communicate with the control room, within one hour establish a watch to monitor the non-communicating fire detection control panel(s).
NOTE HOURLY is defined as "being performed within the clock hour."
CAUTION: Management oversight should be exercised to ensure the intent of the requirement to perform patrols hourly is not undermined. For example, although meeting the above definition, it would not be within the intent of this requirement to perform a patrol of an area at one minute before the hour and one minute after the hour to satisfy a 2-hour period.
SURVEILLANCE REQUIREMENTS TR12-4.3.3.7.1
- Each of the required fire detection instruments shown in the following table which are accessible during plant operation shall be demonstrated functional at least once per 18 months (Heat detectors - 25% every 18 months, all in 6 years)# by performance of a TRIP ACTUATING DEVICE OPERATIONAL TEST.
- Fire detectors which are not accessible during plant operation shall be demonstrated functional by the performance of a TRIP ACTUATING DEVICE OPERATIONAL TEST during each COLD SHUTDOWN exceeding 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> unless performed in the previous 18 months (Heat detectors - 25% every 18 months, all in 6 years).#
TR12-4.3.3.7.2 The NFPA Standard 72D supervised circuits supervision associated with the detector alarms of each of the above required fire detection instruments shall be demonstrated functional at least once per 12 months.
TR12-4.3.3.7.3 The nonsupervised circuits, associated with detector alarms, between the instrument and the control room shall be demonstrated functional at least once per 31 days.
25% surveillance interval extension is not applicable to 6 year frequency.

Technical Requirement 12 Fire Detection Instrumentation (Sheet 3 of 10)
ADDITIONAL INFORMATION Activities required to demonstrate that the fire protection instruments are functional may require technicians to work atop ladders and staging while the plant is at power and create a significant personnel safety hazard. This condition is sufficient to determine that the fire detection instruments are not accessible during plant operation. Therefore, these fire detection instruments should be demonstrated functional by the performance of a TRIP ACTUATING DEVICE OPERATIONAL TEST during each COLD SHUTDOWN exceeding 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> unless performed in the previous 18 months (18 months for smoke detectors).
The logic described above should be applied to any other fire detection instrument which may not be accessible during plant operation. The Station Director or designee should be consulted to determine if other fire detection equipment is inaccessible. When extraordinary means, which can affect the capability to provide safe immediate evacuation or egress for personnel or which constitute a personnel safety hazard, are required to gain access to areas and equipment, that equipment should be considered as inaccessible. Additionally, the appropriate changes should be made to the preventive maintenance scheduling system so that any fire detection instruments determined not to be accessible are demonstrated to be functional during the appropriate COLD SHUTDOWN.

Technical Requirement 13 Containment Penetration Conductor Overcurrent Protective Devices (Sheet 1 of 45)
LIMITING CONDITION FOR OPERATION TR13 The test setpoints and verification times of each containment penetration conductor overcurrent protective device required to be FUNCTIONAL by Technical Requirement 34 shall be as specified herein.
APPLICABILITY: MODES 1, 2, 3 and 4.
ACTION: As specified in TR 34 SURVEILLANCE REQUIREMENTS The test setpoints and verification time of each containment penetration conductor overcurrent protective device is demonstrated by Surveillance Requirement TR 34-4.8.4.2.
ADDITIONAL INFORMATION
- 1. Prior to replacement of any circuit breakers, ensure that the replacement is the same as existing (i.e., frame size, trip size, and manufacturer) including consideration of any usage restrictions given on applicable drawings. This is necessary for test setpoints and verification times listed in the Table to remain applicable. Replacements that are not the same must be evaluated by Engineering prior to installation.
Approved replacement breakers of a different type, as indicated on design drawings and in this table, can be used without any additional Engineering evaluation.
- 2. Certain Type HE breakers with the same trip rating may have different test criteria specified because of usage restrictions.
- 3. Whenever the tie breakers between US-E53 & US-E51 and US-E63 & US-E61 are closed and the incoming breakers opened on US-E53 and US-E63, penetration protection for the loads supplied from US-E53 and US-E63 must be considered nonfunctional. The incoming breakers on US-E51 and US-E61 have not been analyzed for penetration protection and are not listed in the following table of Technical Requirement 13.
- 4. Type ED thermal magnetic breakers may be used as replacements for Type E thermal magnetic breakers as designated in this table. Applicable test setpoints and verification times are provided as appropriate. This substitution is approved for all applicable panels except EDE-PP-112A &
112B branch breakers. Type ED thermal magnetic breakers are considered a different type of breaker than the type E thermal magnetic breakers when performing surveillance testing.
2-13.1 SSTR Rev. 162
Technical Requirement 13 Containment Penetration Conductor Overcurrent Protective Devices (Sheet 2 of 45)
ADDITIONAL INFORMATION (continued)
- 5. Type KD thermal magnetic breakers may be used as replacements for type JL thermal magnetic breakers as designated in this table. Applicable test setpoints and verification times are provided as appropriate. Type KD thermal magnetic breakers are considered a different type of breaker than the type JL thermal magnetic breakers when performing surveillance testing.
- 6. Verification that a breaker trips at the specified current within the required time demonstrates compliance with TR 34. This method of testing is consistent with NEMA AB-2, AB-4 and the vendor's (Telemecanique & NLI) recommendations. Resetting the breaker immediately following a trip provides additional verification that the instantaneous trip device and not the thermal element was responsible for the trip, but is not required to satisfy the surveillance requirement. As the acceptance criterion for response time is 0.167 seconds (equivalent to 10 cycles), the thermal element would not respond quickly enough to provide the trip. Therefore, meeting the time and current acceptance criteria provides verification that the instantaneous trip device functions as required. However, to ensure that the repeated pulsing of current has not resulted in the thermal element tripping the breaker, the breaker should be allowed to cool and then retested at the current which resulted in a successful test or a current higher but still within the allowed range to demonstrate that the instantaneous trip element was responsible for the trip.
Based on the foregoing, the inability to immediately reset a tripped breaker does not constitute a failure of the instantaneous trip test and does not affect the operability of the instantaneous trip function. However, if an attempt to reset the breaker after it has cooled fails, an investigation into the cause of the failure to reset is required to be performed.
- 7. Type HFD thermal magnetic breakers are used as replacements for Type HE3 thermal magnetic breakers as designated in this table. Applicable test setpoints and verification times are provided as appropriate. Type HFD thermal magnetic breakers are considered a different type of breaker than the Type HE3 thermal magnetic breakers when performing surveillance testing.
- 8. Similarly, type HMCP motor circuit protectors are used as replacements for AMPCAP motor circuit protectors as designated in this table, with appropriate testing data provided for these different type devices.
- 9. Similarly, type CR123 thermal overload relays are used as replacements for G30 thermal overload relays as designated in this table, with appropriate testing data provided for these different type devices.

Technical Requirement 15 Protective Devices for Non-Class 1E Circuits Connected to Class 1E Power Sources (Sheet 1 of 17)
LIMITING CONDITION FOR OPERATION TR15 The test setpoints and verification times of each protective device for Non-Class 1E circuits connected to Class 1E power sources required to be FUNCTIONAL by Technical Requirement 34 shall be as specified herein.
APPLICABILITY: MODES 1, 2, 3, 4, 5 and 6.
ACTION: As specified in TR 34.
SURVEILLANCE REQUIREMENTS The test setpoints and verification times of each protective device for Non-Class 1E circuits connected to Class 1E power sources is demonstrated by Surveillance Requirement TR 34-4.8.4.2.
ADDITIONAL INFORMATION
- 1. Prior to replacement of any circuit breakers, ensure that the replacement is the same as existing, i.e., frame size, trip size, manufacturer. This is necessary for test setpoints and verification times listed in the Table to remain applicable. Replacements that are not the same must be evaluated by Engineering prior to installation.
- 2. Type ED may be used as replacements for Type E thermal magnetic breakers as designated in this table. Applicable test setpoints and verification times are provided as appropriate. This substitution is approved for all applicable panels except EDE-PP-112A & 112B branch breakers.
Type ED thermal magnetic breakers are considered a different type of breaker than the type E thermal magnetic breakers when performing surveillance testing.
2-15.1 SSTR Rev. 142
Technical Requirement 15 Protective Devices for Non-Class 1E Circuits Connected to Class 1E Power Sources (Sheet 2 of 17)
ADDITIONAL INFORMATION (continued)
- 3. Verification that a breaker trips at the specified current within the required time demonstrates compliance with TR 34. This method of testing is consistent with NEMA AB-2, AB-4 and the vendor's (Telemechanique) recommendations. Resetting the breaker immediately following a trip provides additional verification that the instantaneous trip device and not the thermal element was responsible for the trip, but is not required to satisfy the surveillance requirement. As the acceptance criterion for response time is <0.067 seconds (equivalent to 4 cycles), the thermal element would not respond quickly enough to provide the trip. Therefore, meeting the time and current acceptance criteria provides verification that the instantaneous trip device functions as required. However, to ensure that the repeated pulsing of current has not resulted in the thermal element tripping the breaker, the breaker should be allowed to cool and then retested at the current which resulted in a successful test or a current higher but still within the allowed range to demonstrate that the instantaneous trip element was responsible for the trip.
Based on the foregoing, the inability to immediately reset a tripped breaker does not constitute a failure of the instantaneous trip test and does not affect the functionality of the instantaneous trip function. However, if an attempt to reset the breaker after it has cooled fails, an investigation into the cause of the failure to reset is required to be performed.

Technical Requirement 19 Feedwater Isolation on Low RCS Tave Coincident with Reactor Trip (Sheet 1 of 2)
LIMITING CONDITION FOR OPERATION TR19: The Feedwater Isolation on Low RCS Tave Coincident with Reactor Trip control function shall be FUNCTIONAL.
- Total No. of Channels - 4
- Minimum Channels for actuation - 2
- Minimum Channels FUNCTIONAL - 3
- Trip Setpoint - greater than or equal to 557°F
- Allowable Value - greater than or equal to 554.3°F.
APPLICABILITY: MODES 1 and 2 ACTION: As determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program. An evaluation is not required if the noncompliance is a consequence of surveillance testing or planned maintenance.
SURVEILLANCE REQUIREMENTS
- A CHANNEL CHECK shall be performed at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
- An ANALOG CHANNEL OPERATIONAL TEST shall be performed at least once per 92 days.
- A CHANNEL CALIBRATION shall be performed at least once per 18 months.
ADDITIONAL INFORMATION The purpose of the feedwater isolation function on low RCS Tavg coincident with a reactor trip is to preclude overcooling events due to continued feedwater flow following a reactor trip. It also has a role in establishing the design transients which form the basis of the system and components design.
After a reactor trip, the average RCS Temperature (Tavg) will decrease to the no-load temperature due to steam dump actuation and continued feedwater flow. Additionally, for reactor trips from power levels above 50%, the shrink in steam generator level typically goes below the lo-lo level setpoint, actuating emergency feedwater (EFW). If feedwater flow is not isolated while the RCS is cooling down, Tavg will undershoot the target value of no-load temperature. The addition of EFW will further aggravate the undershoot effects. This undershoot could subsequently result in safety injection actuation on low RCS pressure as well as loss of required minimum shutdown margin. Consequently, a feedwater isolation on low RCS Tavg coincident with reactor trip has been provided in the design.
However, while the feedwater flow isolation feature is not credited in the safety analysis it does perform a control function. It is intended that the function will remain functional and any changes to the setpoint or function will be controlled pursuant to the requirements of 10 CFR 50.59.

Technical Requirement 19 Feedwater Isolation on Low RCS Tave Coincident with Reactor Trip (Sheet 2 of 2)
ADDITIONAL INFORMATION (continued)
Westinghouse Electric Corporation performs the Loss of Coolant Accident (LOCA) and related analyses for Seabrook Station. Westinghouse confirmed that the LOCA analyses and related analyses, including large and small break LOCA, reactor vessel and loop LOCA blowdown forces, post-LOCA long term core cooling subcriticality, post-LOCA long term core cooling minimum flow and hot leg switchover to prevent boron precipitation are not affected by the low RCS Tavg feedwater isolation setpoint. Feedwater isolation in these analyses is achieved as the result of the initiation of a Safety Injection (SI).

- c. A FUNCTIONAL incore detector location consists of a fuel assembly containing a fixed detector string with a minimum of three FUNCTIONAL detectors.
APPLICABILITY: When the Incore Detector System is used for:
- a. Recalibration of the Excore Neutron Flux Detection System, or
- b. Monitoring the QUADRANT POWER TILT RATIO, or
- c. Measurement of FNH and FQ(Z).

Technical Requirement 21 Seismic Instrumentation (Sheet 1 of 3)
LIMITING CONDITION FOR OPERATION TR21-3.3.3.3 The seismic monitoring instrumentation listed on the following table shall be FUNCTIONAL.
APPLICABILITY: At all times.
ACTION:
As determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program. An evaluation is not required if the noncompliance is a consequence of surveillance testing or planned maintenance.
SURVEILLANCE REQUIREMENTS TR21-4.3.3.3.1 Each of the above required seismic monitoring instruments shown in the seismic monitoring instrumentation surveillance requirements table shall be demonstrated FUNCTIONAL by the performance of:
- a. A Monthly CHANNEL CHECK, and
- b. A Semiannual CHANNEL FUNCTIONAL TEST, and
- c. A Refueling Interval CHANNEL CALIBRATION TR21-4.3.3.3.2 Each of the above required seismic monitoring instruments which is actuated during a seismic event greater than or equal to 0.01 g, and which does not self-reset, shall be restored to FUNCTIONAL status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and a CHANNEL CALIBRATION performed within 30 days following the seismic event. Data shall be retrieved from actuated instruments and analyzed to determine the magnitude of the vibratory ground motion.
ADDITIONAL INFORMATION The function of the seismic instrumentation is to provide information in the event of an earthquake to support a prompt evaluation of the response of Category I structures and components and comparison to the design basis. The seismic instrumentation is capable of recording seismic event after seismic event without operator intervention. Therefore, following actuation of the system by a seismic event or a false trigger, the seismic instrumentation remains functional. Further, the requirements in TR21-4.3.3.3.2 to restore actuated seismic instruments to functional status and perform channel calibrations apply only to instruments that do not self reset. Since the Seabrook instruments self reset, these requirements are normally not applicable following actuation of the seismic instruments.

Technical Requirement 22 Meteorological Instrumentation (Sheet 1 of 3)
LIMITING CONDITION FOR OPERATION TR22-3.3.3.4 The meteorological monitoring instrumentation channels shown in the following table shall be FUNCTIONAL.
APPLICABILITY: At all times.
ACTION:
As determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program. An evaluation is not required if the noncompliance is a consequence of surveillance testing or planned maintenance.
SURVEILLANCE REQUIREMENTS TR22-4.3.3.4 Each of the meteorological monitoring instrumentation channels shown in the following table shall be demonstrated FUNCTIONAL by the performance of:
- a. A Daily CHANNEL CHECK, and
- b. A Semiannual CHANNEL CALIBRATION.
ADDITIONAL INFORMATION Meteorological data can be obtained from either the Primary or Backup Meteorological Monitoring Systems. The Primary Meteorological System (Primary Met Tower) is included in the Seabrook Station Technical Requirements manual. This system is a 210 foot (ft) tower which provides data on the wind speed and direction at 43 ft and 209 ft nominal elevations, and the temperature differential between 43 ft and 150 ft, and 43 ft and 209 ft. The Backup Meteorological System (Backup Met Tower) is a 53 ft tower which provides wind speed and direction at the elevation corresponding to the 43 ft elevation of the Primary Met Tower. An algorithm is used to compute the average upper wind speed, wind direction, and delta-T. The Backup Met Tower was installed to provide meteorological data in the event the Primary Met Tower became unavailable and was not designed to replace the Primary Met Tower for Technical Requirement compliance.
2-22.1 SSTR Rev. 153
Technical Requirement 22 Meteorological Instrumentation (Sheet 2 of 3)
ADDITIONAL INFORMATION (continued)
A CHANNEL CHECK is defined as follows: "A CHANNEL CHECK shall be the qualitative assessment of channel behavior during operation by observation. This determination shall include, where possible, comparison of channel indication and/or status with other indications and/or status derived from independent instrument channels measuring the same parameter." The meteorological instrumentation on the various levels of the Primary Met Tower and on the Backup Met Tower may be subject to variations in local weather conditions. This may cause variances in the data obtained from similar instruments in proximity to one another. In addition, the Backup Met Tower does not directly measure upper wind speed, upper wind direction, and air temperature delta T, but instead uses an algorithm to estimate this data. Consequently, variations in data values among the various Primary and Backup Met Tower channels require further evaluation before a determination of channel nonfunctionality can be made.
The preferred method for performing a CHANNEL CHECK is to compare the upper level and lower level wind speed, wind direction, and air temperature delta T. This comparison can be done using the Main Plant Computer (MPC) or the local indications at the Primary Met Tower. If this method cannot be performed, a CHANNEL CHECK may be done by comparing data from the Primary Met Tower with similar data from the Backup Met Tower. If neither of the two CHANNEL CHECK methods described above is available, then a comparison of Primary Met Tower data with apparent outside weather conditions is acceptable and satisfies the intent of a CHANNEL CHECK.
The following are examples of operational situations and an appropriate CHANNEL CHECK methodology:
Main Plant Computer not available Utilize the local indications at the Primary Met Tower to compare upper and lower level wind speed, wind direction, and air temperature delta T.
Primary Met Tower upper wind speed not available Enter Technical Requirement TR22-3.3.3.4 for the upper wind speed instrument. Perform a CHANNEL CHECK of the lower wind speed instrument by comparison with lower wind speed from the Backup Met Tower.
Primary Met Tower upper wind speed and Backup Met Tower not available Enter Technical Requirement TR22-3.3.3.4 for the upper wind speed instrument. Perform a CHANNEL CHECK of the lower wind speed instrument by comparison with apparent outside weather conditions.

Technical Requirement 23 Turbine Overspeed Protection (Sheet 1 of 2)
LIMITING CONDITION FOR OPERATION TR23-3.3.4 At least one Turbine Overspeed Protection System shall be FUNCTIONAL.
APPLICABILITY: MODES 1, 2, and 3.
ACTION:
With the Turbine Overspeed Protection System nonfunctional, restore the system to functional status within the time period determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program. An evaluation is not required if the noncompliance is a consequence of surveillance testing or planned maintenance.
SURVEILLANCE REQUIREMENTS TR23-4.3.4.1 The above required Turbine Overspeed Protection System shall be demonstrated FUNCTIONAL:
- a. At least once per 90 days by cycling each of the following valves through at least one complete cycle from the running position:
- 1) Four high pressure turbine stop valves, and
- 2) Six low pressure combined intermediate valves.
- b. At least once per 90 days by direct observation of the movement of each of the above valves and at least once per 150 days for the four high pressure turbine control valves through one complete cycle from the running position,
- 1) In the case of using an operational turbine trip and subsequent restart as credit for demonstration of functionality under this provision, direct observation can be defined as:
- Observance of the valve, actuator and its supervisory equipment to be in running position prior to the trip but after the last operation.
- Observance of the valve, actuator and its supervisory equipment to be in the fully closed position after trip actuation, but prior to any attempt to actuate the valve.
- During the restart process subsequent to the trip each valve, actuator and its supervisory equipment is directly observed as it is moved from the closed position to running position.
- The turbine control and monitoring systems indicate no evidence of turbine over-speed from initiation of the trip signal.
2-23.1 SSTR Rev. 158
Technical Requirement 23 Turbine Overspeed Protection (Sheet 2 of 2)
- No work was performed on the valves, actuators or its supervisory equipment during the period from the trip for which credit is desired.
- c. At least once per 18 months by performance of the following:
- 1) a CALIBRATION of the analog to digital conversion devices and
- 2) a digital channel operation test on the Primary and Emergency Turbine Overspeed Protection Systems.
- d. At least once per 40 months by disassembling at least one of each of the above valves and performing a visual and surface inspection of valve seats, disks, and stems and verifying no unacceptable flaws or excessive corrosion. If unacceptable flaws or excessive corrosion is found, all other valves of that type shall be inspected.
ADDITIONAL INFORMATION Surveillance Requirements TR23-4.3.4.1a and TR23-4.3.4.1b both require cycling each valve "from the running position." The requirements of Surveillance Requirements TR23-4.3.4.1a and TR23-4.3.4.1b must be satisfied within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of being able to cycle each valve from its "running position."
Typically, the "running position" for the turbine control valves is greater than 10% open; however, certain plant conditions may result in a "running condition" less than 10% open. In these cases any open valves should be tested.
If the unit is operated at low power levels for extended periods (>90 days), the Surveillance should be performed on those valves which are in their running position to demonstrate their functionality.
The calibration of the analog to digital conversion is the verification that a known frequency input results in a digital output that matches within a defined tolerance. Since these devices are not adjustable, calibration in this context is simply verification of expected performance and does not include adjustment. The digital channel operational test shall consist of exercising the digital computer hardware using database manipulation and/or injecting simulated process data and/or actual operating conditions to verify operability of alarm and/or trip functions for turbine overspeed protection.
Calibration of the sensor is not required because the system performs the automated equivalent of a continuous channel check and will provide alarms if a sensor deviates from other sensors by a predefined amount.
As part of 07DCR005 (EC12635) the mechanical turbine overspeed protection system was removed and replaced with a redundant diverse, electrical overspeed protection system, therefore this surveillance requirement includes tests of both the primary and emergency overspeed protection systems.
The digital turbine control system includes additional protective features/trips associated with the speed signal faults and acceleration/deceleration. These additional protective features/trips are not considered part of the primary and emergency overspeed protection systems. Also, the emergency overspeed protection system includes redundant channels, only one of which is required to be demonstrated as being functional.

Technical Requirement 24 Area Temperature Monitoring (Sheet 1 of 4)
LIMITING CONDITION FOR OPERATION TR24-3.7.10 The temperature of each area shown in Table 24-1 shall not be exceeded.
APPLICABILITY: Whenever the equipment in an affected area is required to be OPERABLE.
ACTION:
If Technical Specification (TS) equipment cannot perform its specified function due to non-functional air conditioning or ventilation equipment (HVAC), then it is necessary to enter the Technical Specification action statement(s) for the affected equipment. Figure 1 provides a listing of HVAC systems and the corresponding most limiting Technical Specification or Technical Requirement for equipment affected by the HVAC systems.
For systems with approved Compensatory Ventilation Plans (CVPs), the OPERABILITY of supported equipment may be satisfied by aligning equipment in the manner specified. The CVPs may include specific time allowances for system re-alignment based on Engineering Area Heat Rate Calculations. For the duration of the approved CVP re-alignment, no additional HVAC limits apply to OPERABLE equipment.
In those instances where compensatory ventilation measures have not been established and an allotted time allowance for room heatup has been provided in OS1023.74, 50% of the time allowance may be used and reset as an iterative process provided that the room temperature is re-evaluated on a periodic basis and efforts continue to restore the air conditioning and ventilation system to normal. Re-evaluation periods shall be based on application of no more than 50% of the allotted time. During this time, the room temperature shall be monitored to ensure compliance with the requirements of TR24-3.7.10.
SURVEILLANCE REQUIREMENTS TR24-4.7.10 The temperature in each of the areas shown in Table 24-1 shall be determined to be within its limit at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
2-24.1 SSTR Rev. 154
Technical Requirement 24 Area Temperature Monitoring (Sheet 2 of 4)
ADDITIONAL INFORMATION The following administrative limitations shall apply during the performance of HVAC system maintenance or testing. This is done to limit the time HVAC equipment is unavailable, assuring the continued ventilation support function for OPERABLE equipment.
For those instances where compensatory ventilation measures have not been established and an iterative allotted time allowance has been applied, a seventy-two (72) hour administrative limit will be applied to ensure expedient efforts are taken to restore the HVAC system to normal. Exceedance of this limit will require approval by the Shift Manager.
For short periods of time (e.g., maintenance, testing, troubleshooting), the substitution of manual action for an automatic system function or for the immediate restoration of HVAC service is allowed. These specific actions must be contained in a procedure or evaluated and documented in approved written instructions with approval by the on-duty Shift Manager. The evaluation shall consider the limitations and requirements of procedure EN-AA-203-1001 to address the use of manual action in place of automatic action.
When air conditioning/ventilation systems alignment not covered by CVPs are not functional and the OPERABILITY of Technical Specification equipment is called into question, OPERABILITY shall be documented using procedure EN-AA-203-1001, Operability Determinations/Functionality Assessments.
Some TS systems are supported by non-TS ventilation systems that consist of two redundant 100%
capacity trains, each capable of supporting both trains of a TS system. These include the following ventilation systems: emergency feedwater pump house, hydrogen analyzer room and hydrogen analyzer electrical room, PCCW pump area, service water pump house, service water pump house electrical rooms, service water cooling tower pump room, and containment enclosure cooling system. A loss of one train of these ventilation systems does not result in a loss of support for either train of TS equipment provided the functional train is capable of being powered from an emergency diesel generator. Both TS trains remain operable, despite a loss of support function redundancy, because the TS definition of operability does not require a TS subsystem's necessary support function to meet single-failure design criterion. Therefore, the TS for the supported system does not limit the duration of the non-TS support system outage even though the single failure design criterion for the supported TS system is not met.
The duration that a redundant 100% capacity ventilation train may remain non-functional for preventative or corrective maintenance is determined in accordance with 10 CFR 50.65(a)(4). If, however, the supporting ventilation train will be nonfunctional for more than 90 days, an evaluation of the configuration change, including consideration of the single failure design consideration, must be made under 10 CFR 50.59. If both trains of the ventilation system are non-functional, then both trains of the supported TS system must be declared inoperable unless an operability determination concludes that the support system is not actually required for operability of the supported TS system or implementation of compensatory actions provides the required support.

LIMITING CONDITION FOR OPERATION TR27-3.9.7 Loads in excess of 2100 pounds shall be prohibited from travel over fuel assemblies in the storage pool.
APPLICABILITY: With fuel assemblies in the storage pool.
ACTION:
With the requirements of the above specification not satisfied, place the crane load in a safe condition.
SURVEILLANCE REQUIREMENTS TR27-4.9.7 Crane interlocks that prevent crane travel with loads in excess of 2100 pounds over fuel assemblies shall be demonstrated FUNCTIONAL within 7 days prior to crane use and at least once per 7 days thereafter during crane operation.
ADDITIONAL INFORMATION The restriction on movement of loads in excess of the nominal weight of a fuel and control rod assembly and associated handling tool over other fuel assemblies in the storage pool ensures that in the event this load is dropped: (1) the activity release will be limited to that contained in a single fuel assembly and (2) any possible distortion of fuel in the storage racks will not result in a critical array. This assumption is consistent with the activity release assumed in the safety analyses.
During Dry Cask Loading operations, the single-failure-proof (in accordance with NUREG-0554,
'Single-Failure-Proof Cranes for Nuclear Power Plants', and compliant with NUREG-0612, 'Control of Heavy Loads') Cask Handling Crane (1-FH-RE-1) shall be utilized for the movement of heavy loads over fuel assemblies located in the Cask Loading Pool. This TR does not apply when using the single-failure-proof crane in accordance with NUREG-0612 requirements.

SURVEILLANCE REQUIREMENTS (continued)
TR28-4.2. Perform a flow balance test, during shutdown, following completion of modifications to the ECCS subsystems that alter the subsystem flow characteristics and verifying that:
- 1) For centrifugal charging pump lines, with a single pump running:
- a. The sum of the injection line flow rates, excluding the highest flow rate, is greater than or equal to 298.3 gpm, and
- b. The total pump flow rate is less than or equal to 549 gpm.
- 2) For Safety Injection pump lines, with a single pump running:
- a. The sum of the injection line flow rates, excluding the highest flow rate, is greater than or equal to 410.4 gpm, and
- b. The total pump flow rate is less than or equal to 669 gpm.

Technical Requirement 29 Boration Systems (Sheet 2 of 9)
ADDITIONAL INFORMATION In general, vents, drains, sampling system connections, and instrument taps are not required to be included in the Surveillance Requirements to verify a system's correct lineup per Technical Requirements. For flowpaths addressed by Technical Requirements, only those valves and other components in the direct flowpath through safety-related equipment whose position is critical to the proper functioning of safety-related equipment, are considered part of the safety-related flowpath.
Sampling connections and instrument taps are not considered to be essential components and thus are not required to be verified in their correct position per Technical Requirements. Vents, drains, and other components not directly in the flowpath, whose position is not critical to the proper functioning of safety-related equipment, are also not required to be verified in their correct position.
A valve that receives an accident signal is allowed to be in a non-accident position provided the valve will automatically re-position upon receipt of an actuation signal within the required stroke time.
Upon a failure to meet the LCO, the action requires suspension of core alterations and positive reactivity changes. Operations that individually add limited, positive reactivity are acceptable when, combined with other actions that add negative reactivity, the overall net reactivity addition is zero or negative. For example, a positive reactivity addition caused by temperature fluctuations from inventory addition or temperature control fluctuations is acceptable if it is combined with a negative reactivity addition such that the overall, net reactivity addition is zero or negative.

2-29.8 SSTR Rev. 122
Technical Requirement 29 Boration Systems (Sheet 9 of 9)
ADDITIONAL INFORMATION Based on the Seabrook Station 10CFR50 Appendix R report, the BATs are required to meet the requirements provided in TR29-3.1.2.6 during Modes 1, 2, and 3. During power operation, the BATs are routinely recirculated to establish a uniform boron concentration and associated surveillance. In addition, the BATs may be isolated for maintenance. The alignment of the BATs to the charging pumps is, however, not required for the system to be considered functional for Appendix R purposes. The following provides the basis for this consideration.
As discussed in 07DCR003 (EC-12633):
Fire safe shutdown analyses assume at the onset of the postulated fire event that all safe shutdown systems (including applicable redundant trains) are operable and available for post-fire safe shutdown. Systems are assumed to be operational with no repairs, maintenance, testing, Limiting Conditions for Operation, etc. in progress. The units are assumed to be operating at full power under normal conditions and normal lineups. These statements are based on NEI document NEI-00-01, Section 3.1.1.3 [now 3.1.1.5].
Based on this, an Appendix R event is not assumed to occur with the system in a surveillance or maintenance alignment.
In accordance with the requirements of Branch Technical Position RSB 5-1, safety grade cold shutdown includes a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> hot standby period followed by a cooldown to RHR cut-in conditions in approximately 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />. Per calculation C-S-1-84214, the BATs need to be aligned by the commencement of plant cooldown. Therefore, operator action to align the BATs is required in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. This provides adequate time for any additional required operator action, should the tanks not be in the normal lineup.

2-33.1 SSTR Rev. 157
Technical Requirement 33 Ultrasonic Mode Calorimetric (Sheet 2 of 8)
ADDITIONAL INFORMATION The maximum allowable reactor core power levels discussed in this Technical Requirement are based on the analyzed reactor core power level assumed in the reactor safety analysis of 3659 MWt and the magnitude of the calorimetric power determination uncertainty which is a function of the calorimetric power determination method.
Calorimetric Power Allowable Safety Maximum Allowable Determination Uncertainty Calorimetric Power Analysis Indicated Reactor Core Determination Power Level Power Level (Reference Calculation) Mode(s) 3659 MWt 0.3% (C-S-1-50035) 3648 MWt Ultrasonic 3659 MWt 2.0% (C-S-1-50031) 3587 MWt Feedwater Flow or Steam Flow Operation at core power levels above 3587 MWt requires a calorimetric power determination uncertainty of less than 2.0%. This is only possible if the Ultrasonic mode calorimetric is used. Therefore, except for the Allowed Outage Time (AOT) described later, operation at reactor core power levels greater than 3587 MWt requires the use of the Ultrasonic mode calorimetric.
The Ultrasonic mode calorimetric is unique in that it receives feedwater mass flow, feedwater temperature and feedwater pressure inputs directly from the LEFM Ultrasonic flow measurement system (1-FW-FIQ-4343-1, -2, -3 and -4). The LEFM system measures and transmits this data more accurately than the equivalent instrumentation for the feedwater flow or steam flow calorimetric modes. This is the basis for the reduced uncertainty that is characteristic of the Ultrasonic mode calorimetric.
The Ultrasonic mode calorimetric can be performed using either of two methods: automatically by the Main Plant Computer System (MPCS) or manually using a non-MPCS calculation. The MPCS method is performed entirely by the MPCS with no operator participation required. The calculated core power for MPCS Ultrasonic mode calorimetric is displayed on Main Control Board (MCB) indicator 1-CP-JI-412 and via several MPCS Satellite Display System (SDS) displays. The manual method is performed by station personnel on a calculating device other than the MPCS and is controlled by a station procedure. The manual Ultrasonic mode calorimetric requires input data gathered directly from the LEFM system via the local displays on the LEFM CPU panels as well as supporting process data provided by either analog points displayed by the MPCS or by alternate measurement methods which satisfy the Ultrasonic mode calorimetric uncertainty assumptions. MCB indicators shall not be used as the source of input data for the manual Ultrasonic mode calorimetric because the increased uncertainty associated with the use of these indicators has not been included in the Ultrasonic mode calorimetric uncertainty analysis.
2-33.2 SSTR Rev. 157
Technical Requirement 33 Ultrasonic Mode Calorimetric (Sheet 3 of 8)
Both the MPCS and manual methods of performing the Ultrasonic mode calorimetric power determination meet the requirements of the uncertainty analysis supporting operation at power levels greater than 3587 MWt. Whenever possible, the MPCS Ultrasonic mode calorimetric should be used to determine reactor core power when operating at power levels greater than 3587 MWt.
LEFM System Functional Status:
For this Technical Requirement, "Functional Status" of the LEFM system is defined as the ability to provide feedwater mass flow, feedwater temperature and feedwater pressure at the required uncertainty level to be used as input for either the MPCS Ultrasonic mode calorimetric calculation or the manual Ultrasonic mode calorimetric calculation. The LEFM data may be retrieved via the LEFM/MPCS datalink application (for the MPCS Ultrasonic mode calorimetric) or locally via the displays on the LEFM CPU panels (for the manual Ultrasonic mode calorimetric).
The LEFM electronics package (1-FW-FIQ-4343-1, -2, -3 and -4) and the MPCS/LEFM datalink application (DALEFZZ.EXE) perform extensive self monitoring and internal diagnostics to ensure proper operation. The LEFM system provides a number of alarms to the Main Plant Computer System (MPCS) Video Alarm System (VAS) to annunciate degraded or failed conditions. These alarms and their associated functional status are described in the table below.

Technical Requirement 33 Ultrasonic Mode Calorimetric (Sheet 5 of 8)
Alarm Alarm Description Alarm Condition LEFM System Status IRTU2 processes the discrete input signals for hardwired LEFM system VAS alarms; D8240 and D8241. These D points are inputs into the "Healthy OR" (HOR) block Failure or NON-FUNCTIONAL F8127. If IRTU2 is out of service, the NONE shutdown of MPCS D points listed above and F8127 will become IRTU #2 (Note 1) status NCAL. This will cause the Ultrasonic mode calorimetric to become invalid.
Calorimetric mode must be changed from Ultrasonic to Steam Flow or Feed Flow.
Notes:
- 1. If the MPCS/LEFM datalink is nonfunctional or IRTU2 is out of service, upon approval from Design Engineering, the LEFM System may be declared FUNCTIONAL to provide data for input to the manual Ultrasonic mode calorimetric calculation. This data would be retrieved via the local displays on the LEFM CPU panels.
MPCS Availability Status:
For this Technical Requirement, "Availability" of the MPCS is defined as the ability of the MPCS to either perform an MPCS Ultrasonic mode calorimetric calculation or to provide supporting process input data for a manual Ultrasonic mode calorimetric calculation via analog points displayed on the MPCS.
"Availability" for various faults is defined in the following table.
Fault Discussion MPCS Availability Failure or shutdown of IRTU #2 and IRTU #8 process the discrete MPCS IRTU #2 or input signals for hardwired LEFM system VAS AVAILABLE IRTU #8 alarms; D8240, D8241, D8506, D8499 and D8500.

MPCS Coldstart Loss of MPCS Calorimetric power calculation and I/O points. Manual calorimetric power calculation and control of reactor core power UNAVAILABLE using the power range NI indicators is required.
Complete MPCS Failure Complete loss of all MPCS functions. Manual calorimetric power calculation and control of UNAVAILABLE reactor core power using the power range NI indicators is required.
Notes:
- 2. Upon approval from Design Engineering, the MPCS may be declared AVAILABLE if the calorimetric input data required to perform a manual (non MPCS) Ultrasonic mode secondary calorimetric power calculation is being displayed by the MPCS or can be measured by alternate methods which satisfy the calorimetric uncertainty assumptions.
Reactor Control Using the NI Power Indicators While the Main Plant Computer System is Unavailable:
Reactor core power limitations for this Technical Requirement shall be based on the highest reading Power Range NI channel. The readability of these indicators is 0.5% of rated thermal power (RTP). The required power level of 98.3% RTP (3587 MWt) has been conservatively rounded down to 98% RTP.
2-33.6 SSTR Rev. 157
Technical Requirement 33 Ultrasonic Mode Calorimetric (Sheet 7 of 8)
A main plant computer system (MPCS) unavailability will be treated as if the Caldon LEFM CheckPlusTM System had also concurrently become nonfunctional. Operation at the rated thermal power level of 3648 MWt (100% RTP) may continue until the next required nuclear instrumentation / power calorimetric comparison, which could be up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The main plant computer system unavailability will result in reducing maximum reactor core power to 98% RTP or less by NI indication, as needed, to support a manual calorimetric power calculation without MPCS display of calorimetric input points or input from the LEFM system. The 48-hour time period will not apply in this specific case.
LEFM System Allowed Outage Time:
The allowed outage time for operation at any reactor core power level in excess 3587 MWt with the Caldon LEFM CheckPlusTM System nonfunctional, is 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, provided steady-state conditions persist (i.e., no power changes below 3587 MWt) throughout the 48-hour period. The bases for the proposed allowed outage time are:
- Alternate plant instruments (feedwater venturies and main steam flow) shall be used if the Caldon LEFM CheckPlusTM System is nonfunctional for greater than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. Specifically, the main steam flow instruments will be normalized to the Caldon LEFM CheckPlusTM System, and their accuracy will gradually degrade over time as a result of nozzle fouling and transmitter drift.
However, values of drift are typically in the range of tenths of a percent of the calibrated span over 18 to 24 months or more. This typical drift value will not result in any significant drift for the instrumentation associated with the calorimetric measurements over a 48-hour period.
- Most repairs to the Caldon LEFM CheckPlusTM System can be made within an eight-hour shift.
Forty-eight hours will give plant personnel time to plan the work, make repairs, and verify normal operation of the Caldon LEFM CheckPlusTM System within its original uncertainty bounds at the same power level and indications as before the failure.
- Operations personnel will operate the plant based on the calibrated alternate plant instruments when the Caldon LEFM CheckPlusTM System is nonfunctional. A reduction in power could, and in many cases, will be avoided altogether since repairs would typically be accomplished prior to the expiration of the 48-hour period.
- License amendment 110 requires that if the plant experiences a power change of greater than ten percent during the 48-hour period, then the permitted maximum allowable reactor core power level will be reduced to 3587 MWt, since a plant transient may result in calibration changes to the alternate instruments. Action statements a and b require that maximum allowable reactor core power be limited to 3587 MWt (98% RTP) if reactor core power is reduced below 3587 MWt (98% RTP). These action statement limits are selected to be consistent with other Technical Specification actions and are conservative to the License Amendment 110 requirements.
For the Caldon LEFM CheckPlusTM System nonfunctional condition, the 48-hour "clock" will start at the time of the failure. Failure will be annunciated in the control room.
2-33.7 SSTR Rev. 157
Technical Requirement 33 Ultrasonic Mode Calorimetric (Sheet 8 of 8)
Use of Alternate Flow Instruments While the Caldon LEFM CheckPlusTM System is Nonfunctional:
The power calorimetric calculation flow inputs using the alternate instrumentation (feedwater venturies or main steam flow) and the Caldon LEFM CheckPlusTM System calorimetric are completely separate, and the calculations of reactor core thermal power are performed independently by the main plant computer system.
The preferred alternate method to provide flow input to the calorimetric power calculation is the main steam flow instruments normalized to the Caldon LEFM CheckPlusTM System flow. The steam flow normalization is performed periodically as needed while the LEFM system is functional by taking the ratio of total steam flow to the feedwater flow from the Caldon LEFM CheckPlusTM System. In addition, the flow input can be provided by either the main steam flow normalized to the venturies, or the feedwater venturies directly. All three methods are bounded by the 2% uncertainty for the maximum reactor core power level of 3587 MWt.

ADDITIONAL INFORMATION Containment electrical penetrations and penetration conductors are protected by demonstrating the FUNCTIONALITY of primary and backup overcurrent protection circuit breakers during periodic surveillance. The Surveillance Requirements applicable to lower voltage circuit breakers provide assurance of breaker reliability by testing at least one representative sample of each manufacturer's brand of circuit breaker. Each manufacturer's air circuit breakers, molded case circuit breakers, and overload devices are grouped into representative samples which are then tested on a rotating basis to ensure that all breakers are tested. If a wide variety exists within any manufacturer's brand of circuit breakers, it is necessary to divide that manufacturer's breakers into groups and treat each group as a separate type of breaker for surveillance purposes.

Technical Requirement 35 Movable Control Assemblies Position Indication System - Shutdown (Sheet 1 of 1)
LIMITING CONDITION FOR OPERATION TR35 One digital rod position indicator (excluding demand position indication) shall be FUNCTIONAL and capable of determining the control rod position within +/- 12 steps for each shutdown or control rod not fully inserted.
APPLICABILITY: MODES 3* **, 4* **, and 5* **
ACTION:
With less than the above required position indicator(s) FUNCTIONAL, immediately open the Reactor Trip System breakers.
SURVEILLANCE REQUIREMENTS The surveillance requirement intended to demonstrate DRPI functionality is covered under Technical Specification Surveillance Requirement 4.1.3.2, for modes when DRPI is required to OPERABLE. DRPI is considered to be FUNCTIONAL if determined to be OPERABLE in accordance with 4.1.3.2.
ADDITIONAL INFORMATION Verification that the DRPI agrees with the demanded position within 12 steps at 24, 48, 120, and 228 steps withdrawn for the control banks and 18, 210, and 228 steps withdrawn for the shutdown banks provides assurances that the DRPI is operating correctly over the full range of indication. Since the DRPI does not indicate the actual shutdown rod position between 18 steps and 210 steps, only points in the indicated ranges are picked for verification of agreement with demanded position.
- With the Reactor Trip System breakers in the closed position.
- See Special Test Exceptions Technical Requirement 36 2-35.1 SSTR Rev. 161
Technical Requirement 36 Special Test Exception Position Indication System - Shutdown (Sheet 1 of 1)
LIMITING CONDITION FOR OPERATION TR36 The limitations of TR35 may be suspended during the performance of individual full-length shutdown and control rod drop time measurements provided;
- a. Only one shutdown or control bank is withdrawn from the fully inserted position at a time, and
- b. The rod position indicator is FUNCTIONAL during the withdrawal of the rods.*
APPLICABILITY: MODES 3, 4 and 5 during performance of rod drop time measurements.
ACTION:
With the Position Indication Systems inoperable or with more than one bank of rods withdrawn, immediately open the Reactor trip breakers.
SURVEILLANCE REQUIREMENTS The above required Position Indication Systems shall be determined to be FUNCTIONAL within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to the start of and every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> thereafter during rod drop time measurements by verifying the Demand Position Indication System and the Digital Rod Position Indication System agree within 12 steps when the rods are stationary.
ADDITIONAL INFORMATION This special test exception permits the Position Indication Systems to be non-functional during rod drop time measurements. The exception is required since the data necessary to determine the rod drop time are derived from the induced voltage in the position indicator coils as the rod is dropped. This induced voltage is small compared to the normal voltage and, therefore, cannot be observed if the Position Indication Systems remain FUNCTIONAL.
- This requirement is not applicable during the initial calibration of the Digital Rod Position Indication System provided: (1) keff is maintained less than or equal to 0.95, and (2) only one shutdown or control rod bank is withdrawn from the fully inserted position at one time.

SEABROOK STATION TECHNICAL REQUIREMENTS Chapter 5 - Programs and Procedures
Technical Requirement Program 5.1 Diesel Fuel Oil Testing Program (Sheet 1 of 4)
This program complies with TS 6.7.6i. It provides controls for the required testing of both new fuel oil and stored fuel oil. For the intent of this program, new fuel oil shall represent diesel fuel oil that has not been added to the DG Fuel Oil Storage Tank(s). Once the fuel oil is added to the DG Fuel Oil Storage Tank(s), the diesel fuel oil is considered stored fuel oil and shall meet the applicable requirements for stored fuel oil.
APPLICABILITY: When associated DG is required to be OPERABLE.
- a. New Fuel Oil The sampling and analysis requirements for new fuel oil are a means to verify that the fuel is of the appropriate grade and has not been contaminated with substances that would have an immediate detrimental impact on diesel engine combustion. The following sampling and analysis requirements apply to new fuel oil:
- 1. New fuel oil is sampled from the delivery tanker in accordance with ASTM D4057-81, "Standard Practice for Manual Sampling of Petroleum and Petroleum Products," prior to addition to the storage tanks.
- 2. Prior to addition to the storage tank(s) the sample is verified using the guidance of the tests specified in ASTM D975-09b, "Standard Specification for Diesel Fuel Oils," to have:
a) An API gravity of within 0.3 degrees at 60ºF, or a specific gravity of within 0.0016 at 60/60ºF, when compared to the bill of lading, or an absolute specific gravity at 60/60ºF of 0.81 and 0.88, or an API gravity of 30 degrees and 42 degrees; b) A flash point 125ºF; c) A kinematic viscosity of 1.9 centistokes and 4.1 centistokes at 40ºC, if gravity was not determined by comparison with the supplier's certification; and d) A clear and bright appearance with proper color when tested in accordance with ASTM D4176-82, "Test Method for Free Water and Particulate Contamination in Distillate Fuels." The centrifuge method specified in ASTM D2709-82, "Test Method for Water and Sediment in Distillate Fuels By Centrifuge," is an acceptable quantitative method of performing this verification. These tests verify that the fuel oil is free of visible water and particulates, and is congruent with the bases identified in T.S. 6.7.6i.
Failure to meet any of the above limits is cause for rejecting the new fuel oil, but is not an OPERABILITY concern since the fuel oil has not been added to the diesel fuel oil storage tanks.
5-1.1 SSTR Rev. 123
Technical Requirement Program 5.1 Diesel Fuel Oil Testing Program (Sheet 2 of 4)
In addition to the tests specified in ASTM D975-09b, the fuel oil is tested to verify a biodiesel content of < 0.1%, which is based on the lower limit of detection for the biodiesel detection equipment. A screening method can be used to verify a biodiesel content of < 2.0%, which is the lower limit of detection for the biodiesel screening equipment, provided that a sample of the fuel oil is tested to verify a biodiesel content of < 0.1% within 31 days. The 31 day period is based on the degradation of stored fuel oil which contains biodiesel being a long term process, allowing remediation of an affected storage tank before it can impact the performance of the emergency diesel generator. If the biodiesel results indicate a biodiesel content > 0.1%, then the storage tank is sampled to verify a biodiesel content < 0.1%. If the biodiesel in the storage tank is > 0.1% then the tank is monitored for particulates and action taken as directed by the corrective action program. The tank is not considered inoperable solely due to biodiesel > 0.1% if particulates are within the acceptable limit as discussed in section b.
- 3. Verify within 31 days of obtaining the new fuel oil sample that the other properties specified in Table 1 of ASTM D975-09b are met when tested in accordance with ASTM D975-09b, except that the analysis for sulfur may be performed in accordance with ASTM D5453-09, "Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oil by Ultraviolet Fluorescence", D7039-07, "Test Method for Sulfur in Gasoline and Diesel Fuel by Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry" or ASTM D2622-07, "Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-ray Fluorescence Spectrometry". If any of the results exceed the required values then the storage tank is sampled to determine if the storage tank values are within the required values and action taken as directed by the corrective action program.
- b. Stored Fuel Oil Fuel oil degradation during long-term storage generally shows up as an increase in particulate contamination, primarily due to oxidation. The presence of particulate contamination does not mean that the fuel oil will not burn properly in a diesel engine.
The particulate contamination can, however, cause fouling of filters and fuel oil injection equipment, which can cause engine failure. The following sampling and analysis requirements apply to stored fuel oil:
5-1.2 SSTR Rev. 123
Technical Requirement Program 5.1 Diesel Fuel Oil Testing Program (Sheet 3 of 4)
- 1. At least once every 31 days, obtain a sample of stored fuel oil in accordance with ASTM D2276-06, "Standard Test Methods for Particulate Contaminant in Aviation Fuels by line Sampling," or ASTM D5452-08, "Standard Test Method for Particulate Contamination in Aviation Fuels by Laboratory Filtration" and verify that total particulate contamination is less than 10 mg/liter when checked in accordance with D6217-98, "Standard Test Method for Particulate Contaminant in Middle Distillate Fuels by Laboratory Filtration" or ASTM D5452-08, "Standard Test Method for Particulate Contamination in Aviation Fuels by Laboratory Filtration." It is acceptable to obtain a field sample in accordance with ASTM D4057-81, "Standard Practice for Manual Sampling of Petroleum and Petroleum Products," for subsequent laboratory testing in lieu of field testing. Where the total stored fuel oil volume is contained in two or more interconnected storage tanks, each storage tank must be considered and tested separately. The 31-day frequency of this analysis considers fuel oil degradation trends that indicate that particulate contamination is not likely to change significantly during the interval.
Note: A composite sample should be taken at multi levels within the diesel generator fuel oil storage tanks. This method of sampling will provide for more consistent data acquisition to enhance trend analysis of particulate matter. (See Engineering Evaluation 90-33 for additional details.)
- 2. Stored fuel oil total particulates not within limits shall be restored within limits within 7 days. Since the presence of particulates does not mean failure of the fuel oil to burn properly in the diesel engine, and particulate concentration is unlikely to change significantly between Surveillance Frequency intervals, and proper engine performance has been recently demonstrated (within 31 days), it is prudent to allow a brief period prior to declaring the associated EDG inoperable. The 7 day completion time allows for further evaluation, re-sampling and re-analysis of the EDG fuel oil, and restoration actions, as required.
- 3. Stored fuel oil, when mixed with new fuel oil having properties not meeting the requirements specified in TRP 5.1a.3, above, shall have its fuel oil properties restored within limits within 30 days. The 30 day time interval considers that even if a DG start and load was required during this time interval, with fuel oil properties outside the limits, there is a high likelihood that the DG would still be capable of performing its intended function.
- 4. TS 4.8.1.1.2b and 4.8.1.1.2c set the frequency and conditional requirements for checking for water in the day and storage tanks. The analytical methodology to be used shall be ASTM D4176, ASTM D2709 or ASTM equivalent test for water in the fuel oil.
5-1.3 SSTR Rev. 123
Technical Requirement Program 5.1 Diesel Fuel Oil Testing Program (Sheet 4 of 4)
- c. At least once per 10 years, each fuel oil storage tank shall be drained, the accumulated sediment removed, and the tanks cleaned using a sodium hypochlorite solution, or equivalent.
The presence of sediment does not necessarily represent a failure of this surveillance requirement, provided that accumulated sediment is removed during performance of the Surveillance.

Technical Requirement Program 5.3 Containment Leakage Rate Testing Program (Sheet 1 of 1)
This Technical Requirement Program implements the requirements of Technical Specification (TS) 6.15, Containment Leakage Rate Testing Program (CLRTP). The program implements the leakage rate testing of the containment as required by 10 CFR 50.54(o) and 10 CFR 50, Appendix J, Option B, as modified by approved exemptions. The program is in accordance with the guidelines contained in Regulatory Guide 1.163, "Performance-Based Containment Leak Test Program, dated September 1995,"
as modified by approved exceptions. The specific implementation details are located in the Leakage Test Reference Manual (SLTR).
The provisions of Technical Specification 4.0.2 are not applicable to the CLRTP.
The provisions of Technical Specification 4.0.3 are applicable to the CLRTP.

Technical Requirement Program 5.4 Standby Emergency Diesel Generator Inspection Program (Sheet 1 of 2)
Requirement:
Each diesel generator shall be demonstrated OPERABLE at least once per 18 months*, during shutdown#, by subjecting the diesel to an inspection in accordance with procedures prepared in conjunction with its vendor/owner's group recommendations for this class of standby service. In addition, other diesel generator inspection / surveillance activities identified on the following table shall be performed at the frequencies specified.
Note:
The words "prepared in conjunction with" do not mean that compulsory acceptance of all vendor/owner's group recommendations is necessary.
Ensuring EDG OPERABILITY and reliability is the overall goal of this Requirement and considering vendor/owner's group recommendations contributes to the achievement of that goal. The bases for demonstrating OPERABILITY of the diesel generators are in accordance with the recommendations of Regulatory Guide 1.108, "Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977. This Guide does not include any level of detail addressing specific maintenance activities or the need for verbatim compliance with vendor/owner's group recommendations.
In some instances vendor/owner's group recommendations may be overly conservative, prescriptive, or not applicable due to site specific applications. The FPL Energy Seabrook system engineer and maintenance personnel are cognizant of the site specific EDG operating experience which may be used to develop superior inspection alternatives that have a decided time savings advantage or cost benefit over vendor/owner's group recommendations.
Vendor/owner's group inspection recommendations are not regulatory requirements. FPL Energy Seabrook should use sound engineering judgment regarding the inclusion of, or omission of, vendor/owner's group recommendations in maintenance and inspection procedures. The safety significance of the EDGs warrants that any omission of vendor/owner's group recommendations or any use of alternatives should be justified by an evaluation that shows there is no compromise in EDG reliability or OPERABILITY. This evaluation shall be documented in the Preventative Maintenance Technical Basis. Basis for recommendations that will not be implemented shall be documented in the Corrective Action System.
- Selected inspection activities may be performed at frequencies other than 18 months provided a documented evaluation supports performance of that activity at a different frequency. Frequency changes shall be documented in the Preventative Maintenance Technical Basis.
Selected surveillance requirements, or portions thereof, may be performed during conditions or modes other than shutdown, provided an evaluation supports safe conduct of that surveillance in a condition or mode that is consistent with safe operation of the plant. (ref. NRC GL 91-04) 5-4.1 SSTR Rev. 87

4.0 INSTRUCTIONS 4.1 General Requirements Snubbers shall be examined and tested in accordance with the ASME OM Code, Subsection ISTD, 2004 Edition. Snubber attachment hardware shall be examined in accordance with ASME Section XI, Subsection IWF, 2004 Edition. Refer to program implementing procedure ER-AA-119-1000, Snubber Program Procedure.
4.2 Snubber Visual Examination Snubber Visual Examination shall be performed in accordance with ISTD-4000 of the ASME OM Code. The visual examination of snubber attachment hardware shall be performed in accordance with Article IWF-5000 of ASME Section XI, 2004 Edition.
4.2.1 Snubber Categorization Each snubber has been categorized as inaccessible or accessible during reactor operation. Based on the inaccessible and accessible categorization, each category of snubbers may be considered separately for examination.
5-5.1 SSTR Rev. 158
Technical Requirement Program 5.5 Seabrook Station Snubber Inservice Inspection Program (Sheet 2 of 5) 4.2.2 Snubber Visual Examination Acceptance Criteria Snubber visual examinations shall meet all the following requirements to be considered OPERABLE:
Restrained Movement: Snubbers shall be installed so they are capable of restraining movement when activated. Examinations shall include observations for the following and the conditions shall be evaluated when found:
(a) loose fasteners, or members that are corroded or deformed; (b) Disconnected components or other conditions that might interfere with the proper restraint of movement.
Snubbers evaluated to be incapable of restraining movement shall be classified unacceptable.
Thermal Movement: Snubber installations shall not restrain thermal movement to an extent that unacceptable stresses could develop in the snubber, the pipe, or other equipment that the snubber is designed to protect or restrain. This requirement is satisfied if no indication of binding, misalignment, or deformation of the snubber is observed.
Design-Specific Characteristics: Snubbers shall be free of defects that may be generic to particular designs as may be detected by visual examination. For example, fluid supply or content for hydraulic snubbers shall be observed. An observation that the fluid level is equal to or greater than the minimum specified amount that is sufficient for actuation at its operating extension is considered to satisfy this requirement. If the fluid is less than the minimum amount, the installation shall be identified as unacceptable, unless a test establishes that the performance of the snubber is within specified limits. The initial test shall start with the piston at the as-found setting and be performed in the extension (tension) direction, or in a mode that more closely resembles the operating and design requirements of the snubber.
Attachment Hardware: Snubber attachment hardware shall be free of the following conditions:
(a) deformations or structural degradations of fasteners, springs, clamps, or other support items; (b) missing, detached, or loosened support items; (c) arc strikes, weld spatter, paint, scoring, roughness, or general corrosion on close tolerance machined or sliding surfaces; (d) misalignment of supports; (e) improper clearances of guides and stops.

Technical Requirement Program 5.5 Seabrook Station Snubber Inservice Inspection Program (Sheet 3 of 5) 4.2.3 Snubber Visual Examination Failure Evaluation Snubbers that do not meet examination requirements of 4.2.2 shall be evaluated to determine the root cause of the unacceptability.
Snubber attachment hardware that does not meet the requirements of 4.2.2 shall be evaluated.
4.2.4 Snubber Visual Examination Corrective Action Unacceptable snubbers and snubber attachment hardware shall be adjusted, repaired, modified, or replaced. Repairs and replacements shall be in accordance with ASME Section XI, Article IWA-4000. Additional action regarding the examination interval shall be taken as required.
4.3 Snubber Testing Snubbers shall be tested for operational readiness during each fuel cycle. Tests are required to be in accordance with a specified sampling plan. Testing shall be performed during normal system operation, or during system or plant outages. The Seabrook administrative procedures govern removing snubbers from operable system(s). For each snubber determined to be unacceptable by operational readiness testing, additional snubbers shall be tested as determined by the type of failure and the corrective action taken.
4.3.1 Snubber Testing Defined Test Plan Groups (DTPGs)
Seabrook snubbers are separated into Types or Defined Test Plan Groups, which are based on the snubber design and manufacturer (and not the snubber capacity).
4.3.2 Snubber Testing Sampling Plan Seabrook has elected to implement the 10% Testing Sample Plan.
5-5.3 SSTR Rev. 158
Technical Requirement Program 5.5 Seabrook Station Snubber Inservice Inspection Program (Sheet 4 of 5)
NOTE Prior to initiation of the first Seabrook snubber testing program per the ASME OM Code, the NRC Regional Administrator was notified that the 10% Sampling Plan would be used (Ref. NYN 91053). Because the current snubber testing program also utilizes the 10% Sampling Plan, no additional NRC notifications are required. If another plan were to be used, these Technical Requirements must be revised and the NRC Regional Administrator must be notified of the change in writing prior to use of the new sample plan.
4.3.3 Snubber Testing Acceptance Criteria Snubber testing shall meet all of the following requirements to be considered OPERABLE:
(a) activation is within the specified range of velocity or acceleration in tension and in compression.
(b) release rate, when applicable, is within the specified range in tension and in compression.
For units specifically required not to displace under continuous load, ability of the snubber to withstand load without displacement.
(c) for mechanical snubbers, drag force is within specified limits, in tension and in compression.
4.3.4 Transient Event Inspection An inspection shall be performed of all snubbers attached to sections of systems that have experienced unexpected, potentially damaging transients as determined from a review of operational data and a visual inspection of the systems within 6 months following such an event.
In addition to satisfying the visual inspection acceptance criteria, freedom-of-motion of mechanical snubbers shall be verified using at least one of the following: (1) manually induced snubber movement; or (2) evaluation of in-place snubber piston setting; or (3) stroking the mechanical snubber through its full range of travel.
4.3.5 Test Failure Evaluation Snubbers that do not meet test requirements specified in 4.3.3 or the applicable Qualitative Tests shall be evaluated to determine the root cause of the failure, as follows:
(a) The evaluation shall include review of information related to other unacceptable snubbers found during testing that refueling outage.
(b) The evaluation results shall be used, as applicable, to determine Failure Mode Groups (FMGs) to which snubbers should be assigned. Additional justifying information should be used to assign snubbers with failures previously identified as unexplained or isolated to an appropriate FMG.
5-5.4 SSTR Rev. 158
Technical Requirement Program 5.5 Seabrook Station Snubber Inservice Inspection Program (Sheet 5 of 5) 4.3.6 Corrective Action Unacceptable snubbers shall be adjusted, repaired, modified, or replaced. Snubbers that do not meet the test requirements of 4.3.3 or the applicable Qualitative Tests shall be functionally tested as required.
4.4 Snubber Service Life Monitoring Program Service life shall be evaluated at least once each fuel cycle, and increased or decreased, if warranted. Evaluation shall be based upon technical data from representative snubbers that have been in service in the plant, or other information related to service life. If the evaluation indicates that service life will be exceeded before the next scheduled system or plant outage, one of the following actions shall be taken:
(a) the snubber shall be replaced with a snubber for which the snubber life will not be exceeded before the next scheduled system or plant outage.
(b) technical justification shall be documented for extending the service life to or beyond the next scheduled system or plant outage.
(c) the snubber shall be reconditioned such that its service life will be extended to or beyond the next scheduled system or plant outage.
Critical parts shall be replaced so that the maximum service life will not be exceeded during a period when the snubber is required to be OPERABLE. The parts replacements shall be documented and the documentation shall be retained in accordance with the Quality Assurance Topical Report (QATR).

Technical Requirement Program 5.6 Post Accident Assessment Program (Sheet 1 of 1)
This Technical Requirement Program establishes, implements and maintains the Post Accident Assessment Program (PAAP) at Seabrook Station. The PAAP ensures the capability to obtain information about the radionuclides existing post-accident. The information would allow those with decision-making responsibilities to plan for long-term recovery operations and limit the public's ingestion of radioactive materials. The program includes the following:
- 1) The capability for classifying fuel damage events at the Alert level threshold of 300 microcuries per ml dose equivalent iodine (DEI) or 3000 microcuries per ml gross activity.
- 2) Contingency plans for obtaining and analyzing highly radioactive samples of reactor coolant, containment sump (including pH), and containment atmosphere (including hydrogen).
- 3) The capability to monitor radioactive iodines that have been released to offsite environs.
NOTE Changes to the PAAP and associated implementing procedures will require the following determinations:
- 1. Whether the change decreases the effectiveness of the emergency plan in accordance with the provisions of 10 CFR 50.54(q) requirements, and
- 2. Assess the impact on Core Damage Assessment Methodology (CDAM).

It is recognized that exactly equal values cannot always be dialed into the numerator and denominator in the protection system hardware, even if the nominal values are the same (10 seconds). Thus given the inequality sign in the COLR (greater than or equal to) the intent of the definition of this time constant applies primarily to the rate time constant (i.e. the Tau value in the numerator). The lag time constant (denominator Tau value) may be less than 10 seconds or less than the value of the numerator Tau value (e.g., if the numerator is set at 10.5, the denominator may be set to 10 or 9.5) and still satisfy the intent of the anticipatory protective feature.
