APPLICABILITY I
SURVEILLANCE REQUIREMENTS (Continued) b.
Surveillance intervals specified in Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda for the inservice inspection and testing activities required by the ASME Boiler and Pressure Vessel Code and applicable Addenda shall De applicable as follows in these Technical Specifications:
ASME Boiler and Pressure Vessel Required frequencies for Code and applicable Addenda performing inservice terminology for inservice inspection and testing inspection and testing activities activities Weekly At least once per 7 days Monthly At least once per 31 days Quarterly or every 3 months At least once per 92 days Semiannually or every 6 months At least once per 184 days Every 9 months At least once per 276 days Yearly or annually At least once per 366 days c.
The provisions of Specification 4.0.2 are applicable to the above required frequencies for performing inservice inspection and testing activities; d.
Performance of the above inservice inspection and testing activities shall be in addition to other specified Surveillance Requirements; and e.
Nothing in the ASME Boiler and Pressure Vessel Code shall be construed to supersede the requirements of any Technical Specification.
4.0.6 Surveillance Requirements shall apply to each unit individually unless otherwise indicated as stated in Specification 3.0.5 for individual specifica-tions or whenever certain portions of a specification contain surveillance parameters different for each unit, which will be identified in parentheses, footnotes or body of the requirement.
SOUTH TEXAS - UNITS 1 & 2 3/4 0-4 UNIT 1 - AMENDMENT NO. 4
3.4.0 _ APPLICABILITY BASES (Continued)
The time limits of Specification 3.0.3 allow E hours for the plant to be in the COLD SHUTDOWN MODE when a shutdown is required during the POWER MODE of operation.
If the plant is in a lower MODE of operation when a shute:own is required, the time limit for reaching the next lower MODE of operation ap-plies.
However, if a lower MODE of operation is reached in less time than allowed, the total allowable time to reach COLD SHUTDOWN, or other app 1' cable MODE, is not reduced.
For example, if HOT STANDBY is reached in 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, the time allowed to reach HOT SHUTDOWN is the next 11 hours1.273148e-4 days <br />0.00306 hours <br />1.818783e-5 weeks <br />4.1855e-6 months <br /> because the total time to reach HOT SHUTDOWN is not reduced from the allowable limit of 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />.
Therefore, if remedial measures are completed that would permit a return to POWER operation, a penalty is not incurred by having to reach a lower MODE of operation in less than the total time allowed.
The same principle applies with regard to the allowable outage time limits of the ACTION requirements, if compliance with the ACTION requirements for one specification results in entry into a MODE or condition of operation for another specification in which the requirements of the Limiting Condition for Operation are not met.
If the new specification becomes applicab H in less time than specified, the difference may be added to the allowable ouute time limits of the second specification.
However, the allowable outage time limits of ACTION requirements for a higher MODE of operation may not be used to extend the allowable outage time that is applicable when a Limiting Condition for Operation is not met in a lower MODE of operation.
The shutdown requirements of Specification 3.0.3 do not apply in.'40 DES 5 and 6, because the ACTION requirements of individual specifications define the remedial measures to be taken.
Specification 3.0.4 establishes limitations on MODE cha7ges when a Limiting Condition for Operation is not met.
It precludes placing the facility in a higher MODE of operation when the requirements for a Limiting Condition for Operation are not met and continued noncompliance to these conditions would result in a shutdown to comply with the ACTION requirements if a change in MODES were permitted.
The purpose of this specification is to ensure that facility operation is not initiated or that higher MODES of operation are not entered when corrective action is being taken to obtain compliance with a specification by restoring equipment to OPERABLE status or parameters to specified limits.
Compliance with ACTION requirements that permit continued operation of the facility for an unlimited period of time provides an accept-able level of safety for continued operation without regard to the status of the plant before or after a MODE change.
Therefore, in this case, entry into an OPERATIONAL MODE or other specified condition m,ay be made in accordance with the provisions of the ACTION requirements.
The provisions of this specification should not, however, be interpreted as endorsing the failure te exercise good practice in restoring systems or components to OPERABLE status before plant startup.

3.4.0 APPLICABILITY I
BASES (Continued)
When a shutdown is required to comply with ACTION requirements, the provisions of Specification 3.0.4 to not apply because they would delay placing the facility in a lower MODE of operation.
Specification 3.0.5 delineates the applicability of each specification to Unit 1 and Unit 2 operation.
Specifications 4.0.1 through 4.0.6 establish the generai requirements applicable to Surveillance Requirements.
These requirements are based on the Surveillance Requirements stated in the Code of Federal Regulations, 10 CFR S0.36(c)(3):
" Surveillance requirements are requirements relating to test, calibra-tion, or inspection to ensure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions of operation will be met."
Specification 4.0.1 establishes the requirement that surveillances must be performed during the OPERATIONAL MODES or other conditions for which the requirements of the Limiting Conditions for Operation apply unless otherwise stated in an individual Surveillance Requirement.
The purpose of this speci-fication is to ensure that surveillances are performed to verify the opera-
' tional status of systems and components and that parameters are within speci-fied limits to ensure sefe operation of the facility when the plant is in a MODE or other specified condition for which the associated Limiting Conditions for Operation are applicable.
Surveillance Requirements do not have to be performed when the facility is in an OPERATIONAL MODE for which the requirements of the associated Limiting Condition for Operation do not apply unless otherwise specified.
The Surveillance Requirements associated with a Special Test
. Exception ara only applicable when the Special Test Exception is used as an allowable exception to the requirements of a specification.
Specification 4.0.2 establishes the limit for which the specified time interval for Surveillance Requirements may be extended.
It permits an allowable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operating conditions that may not be suitable for conducting the surveillance; e.g., transient conditions or other ongoing surveillance or maintenance activities.
It also provides flexibility to accommodate the length of a fuel cycle for surveillances performed at each refueling outage and are specified with a 18-month surveillance interval.
It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances not performed during refueling outages.
The limitation of Specification 4.0.2 is based on engineering judgment and the recognition that the most probable result of any particular surveillance being performed is verification of conformance with the Surveillance Requirements.
This provision is sufficient to ensure that reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.
Specification 4.0.3 establishes the failure to perform a Surveillance T(equirement within the allowed surveillance interval, defined by the provisions of Specification 4.0.2, as a condition that constitutes a failure to meet the SOUTH TEXAS - UNITS 1 & 2 B 3/4 0-4 UNIT 2 - AMENDMENT N0.
