Logical Connectors 1.2 1.0 USE AND APPLICATION

1.2 Logical

Connectors The purpose of this section 1S to explain the meaning of logical connectors.

Logical connectors are used in Technical Specifications (TS)to discriminate between, and yet connect. discrete Conditions, Required Actions, Completion Times, Surveillances, and Frequencies.

The only logical connectors that appear in are AND and OR. The physical arrangement of these connectors constituteS-logical conventions with specific meanings.

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

When logical connectors are used to state a Condition, Completion Time. Surveillance.

or Frequency, only the first level of logic used, and the logical connector is left justified with the statement of the Condition, Completion Time, Surveillance, or Frequency.

EXAMPLES The following examples illustrate the use of logical connectors.

Required Actions A.1. A.2.

and A.3 are alternative choices. only one of which must be performed as indicated by the use of the logical connector OR and the left justified placement.

Anyone of these three Actions may be chosen. If A.2 is chosen. then both A.2.1 and A.2.2 must be performed as indicated by the logical connector AND. Required Action A.2.2 is met by perform-ing A.2.2.1 or A.2.2.2. The indented position of the logical connector OR indicates that A.2.2.1 and A.2.2.2 are alternative cnoices. only one of which must be performed.

Completion Times 1.3 1.0 USE AND APPLICATION

1.3 Completion

Times PURPOSE The purpose of this section is to establish the Completion Time convention and to provide guidance for its use. BACKGROUND Limiting Conditions for Operation (LCOs) specify minimum requirements for ensuring safe operation of the unit. The ACTIONS associated with an LCD state Conditions that typically describe the ways in which the requirements of the LCO can fail to be met. Specified with each stated Condition are Required Action(s) and Completion Time(s).

The Completion Time is the amount of time allowed for completing a Required Action. It is referenced to the time of discovery of a situation (e.g .. inoperable equipment or variable not within limits) that requires entering an ACTIONS Condi on unless otherwise specified.

providing the unit is in a MODE or specified condition stated in the Applicability of the LCD. Required Actions must be completed prior to the expiration of the specified Completion Time. An ACTIONS Condition remains in and the Required Actions apply until the Condition no longer exists or the unit is not within the LCD Applicability.

If situations are discovered that require entry into more than one Condition at a time within a single LCO (multiple Conditions), the Required Actions for each Condition must be performed within the associated Completion Time. When in multiple Condi ons, separate Completion Times are tracked for each Condition starting from the time discovery of the situation that required entry into the Condition.

Once a Condition has been entered, subsequent trains. subsystems, components.

or variables expressed in the Condition.

discovered to be inoperable or not within limits. will not result in separate entry into the Condition.

unless specifiCally stated. The Required Actions of the Condition continue to to each additional failure. with Completion Times based on initial entry into the Condition. (continued)

However. when a subsequent train. subsystem.

or variable expressed in the Condition is discovered to be inoperable or not within limits. the Completion Time(s) may be extended.

To apply this Completion T-ime extension.

two criteria must first be met. The subsequent inoperability: Must exist concurrent with the first inoperability;Must remain inoperable or not within limi after the first inoperability is resolved.

or variable expressed in the Condition) and separate tracking of Compl on Times based on this re-entry.

These exceptions are stated in individual The above Completion Time extension does not apply to Completion me with a modified "time zero." This "time zero" may be expressed as a repetitive time (i .e ..

Completion Times 1.3 1.3 Completion Times EXAMPLES EXAMPLE 1.3 3 (continued)

When one Function X train and one Function Y train are inoperable, Condition A and Condition B are concurrently applicable.

The Completion Times for Condition A and Condition B are tracked separately for each train starting from the time each train was declared inoperable and the Condition was entered. A separate Completion Time is established for Condition C and tracked from the time the second train was declared inoperable (i .e., the time the situation described in Condition C was discovered).

If Required Action C.2 is completed within the specified Completion me, Conditions Band C are exited. If the Completion Time for Required Action A.l has not expired, operation may continue in accordance with Condition A. The remaining Completion Time in Condition A is measured from the time the affected train was declared inoperable (i .e., initial entry into Condition A). The Completion Times of Conditions A and B are modified by a logical connector, with a separate 10 day Completion me measured from the time it was discovered the LCD was not met. In this example, without the separate Completion Time, it would be possible to alternate between Conditions A. B. and C in such a manner that operation could continue indefinitely without ever restoring systems to meet the LCD. The separate Completion Time modified by the phrase "from di scovery fail ure to meet the LCD" is desi gned to prevent indefinite continued operation while not meeting the LCD.

Frequency 1.4 1.0 USE AND APPLICATION

1.4 Frequency

PURPOSE The purpose of this section is to define the proper use and application of Frequency requirements. Each Surveillance Requirement (SR) has a speci ed Frequency in which the Surveillance must be met in order to meet the associated LCD. An understanding of the correct application of the specified Frequency is necessary for compliance with the SR. The "specified Frequency" is referred to throughout this section and each of the Specifications of Section 3.0, Reql.rirement (SR) Applicability.

The "specified Frequency" consists of the requirements of the Frequency column of each SR, as well as certain Notes in the Surveillance column that modify performance requirements.

Situations where a Surveillance could be required (i .e., its Frequency could expire). but where it is not possible or not desired that it be performed until sometime after the associated LCD is within its Applicability, represent potential SR 3.0.4 conflicts.

To avoid these conflicts.

the SR (i .e .. the Surveillance or the Frequency) is stated such that it is only "required" when it can be and should be performed.

With an SR satisfied.

SR 3.0.4 imposes no restriction.

EXAMPLES The following examples illustrate the various ways that Frequencies are specified.

In these examples.

the Applicability of the LCD (LCD not shown) is MODES 1. 2. and 3.

Performance of the Surveillance initiates the subsequent interval.

Although the Frequency is stated as 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. an extension of the time interval to 1. times the stated Frequency is allowed by SR 3.0.2 for operational flexibility.

The measurement of this interval continues at all times. even when the SR is not required to be met per SR 3.0.1 (such as when the equipment is inoperable.

a variable is outside specified limits, or the unit is outside the Applicability of the LCD). If the interval specified by SR 3.0.2 is exceeded while the unit is in a MODE or other specified condition in the Applicability of the and the performance of the Surveillance is not otherwise modified (refer to Example 1.4-3). then SR 3.0.3 becomes applicable.

If the interval as specified by SR 3.0.2 is exceeded while the unit is not in a MODE or other specified condition in the Applicability of the LCD for which performance of the SR is required, then SR 3.0.4 becomes applicable.

The Surveillance must be performed within the Frequency requirements of SR 3.0.2 prior to entry into the MODE or other specified condition.

The first is a one time performance Frequency, and the second is of the type shown in Example 1.4-1. The logical connector "AND" indicates that both Frequency requirements must be met. Each time reactor power is increased from a power level < 25% RTP to 25% RTP, the Surveillance must be performed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The use of "once" indicates a single performance will satisfy the specified Frequency (assuming no other Frequencies are connected by "AND"). This type of Frequency does not qualify for the extension allowed by SR 3.0.2. "Thereafter" indicates future performances must be established per SR 3.0.2, but only after a specified condition is first met (i .e., the "once" performance -in this example).

If reactor power decreases to < 25% RTP, the measurement of both intervals stops. New intervals start upon reactor power reaching 25% RTP.

7 The interval continues, whether or not the unit operation is < 25% RTP between performances.

As the Note modifies the required performance of the Surveillance, it is construed to be part of the "specified Frequency." Should the 7 day interval be exceeded while operation is < 25% RTP, this Note allows 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after power reaches 25% RTP to perform the Surveillance.

The Surveillance is still considered to be performed within the "specifi ed Frequency." Therefore.

if the Survei 11 ance were not performed within the 7 day (plus the extension allowed by SR 3.0.2) interval.

but operation was < 25% RTP, it would not constitute a failure of the SR or failure to meet the LCD. Also, no violation of SR 3.0.4 occurs when changing MODES. even with the 7 day Frequency not met. provided operation does not exceed 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> with power 25% RTP.

• 9 3 4 4 4 4 S 5 6 7 7 7 9 9 9 9 9 1.0 Objectives of the Environmental Protection Plan The Environmental Protection Plan (EPP) is to provide for protection of environmental values during construction and operation of the nuclearfacility. The principal objectives of the EPP are as follows: (1) Verify that the station is operated in an environmentally acceptable manner, as established by the FES and other NRC environmental impact assessments.

• (2) Coordinate NRC requirements and maintain consistency with other Federal, State and local requirements for environmental protection.

(3) Keep NRC informed of the environmental effects of facility construction and operation and of actions taken to control those effects. 2.0 Environmental Protection Issues In the FES-OL dated February 1982, the staff considered the environmental impacts associated with the operation of the Palo Verde Nuclear Generating Station. Certain environmental issues were identified which required study or license conditions to resolve environmental concerns and to assure adequate protection of the environment.

2.1 Aquatic

Issues Because there will be no station effluents discharged to natural surface water bodies, station operation will have no direct adverse impacts on the qualityof surface water. Therefore, there are no aquatic issues raised by the staff in the FES-OL.2.2 Terrestrial Issues No new terrestrial issues requiring environmental monitoring programs were identified in the FES-OL. The FES-CP did identify a program for monitoring the effects of salt deposition due to cooling tower drift. The requirements for this program specified in Subsection 4.2.2 of this EPP.2.3 Cultural Resources Issues Upon resolution of the final alignment of the PVNGS-to-Saouaro transmission line, the applicant will conduct an appropriate cultural resource survey relative to the corridor for NRC review and evaluation pursuant to condition 7.f. of the construction permit (FES-CP, p. iii). There is a need to protect any cultural resources sites identified in the survey which may be eligiblefor or which are included in the National Register of Historic Places. NRC requirements with regard to the cultural resources issues are specified in Subsection 4.2.1 of this EPP._ _ 3.0 Consistency Requirements

3.1 Plant

Design and Operation The licensees may make chances in station design or operation or perform tests or experiments affecting the environment provided such changes, tests or experiments do not involve an unreviewed environmental question, and do not involve a change in the Environmental Protection Plan. Changes in plant design or operation or performance of tests or experiments which do not affect the environment are not subject to the requirements of this EPP. Activities governed by Subsection 3.2 of this EPP are not subject to the requirements-of this subsection.

Before enaaginq in additional construction or operational activities which may affect the environment, the licensees shall prepare and record an environmental evaluation of such activity*.

When the evaluation indicates that such activity-involves an unreviewed environmental question, the licensees shall provide a written evaluation of such activities and obtain prior approval from the NRC.When such activity involves a chance in the Environmental Protection Plan, such activity and change to the Environmental Protection Plan may be implemented only in accordance with an appropriate license amendment as set forth in Subsection 5.3 of this EPP.A proposed change, test or experiment shall be deemed to involve an unreviewed environmental question if it concerns (1) a matter which may result in a significant increase in any adverse environmental impact previously evaluated in the Final Environmental Statement (FES) as modified by staff's testimony to the Atomic Safety and Licensing Board, supplements to the FES, environmental impact appraisals, or in any decisions of the Atomic Safety and Licensing Board; or (2) a significant change in effluents or power level or (3) a matter not previously reviewed and evaluated in the documents specified in (1) of this subsection, which may have a significant adverse environmental impact.The licensees shall maintain records of changes in facility design or operation and of tests and experiments carried out pursuant to this subsection.

These records shall include a written evaluation which provide bases for the deter-mination that the change, test, or experiment does not involve an unreviewed environmental question nor constitute a decrease in the effectiveness of this EPP to meet the objectives specified in Section 1.0. The licensees shall include as part of their Annual Environmental Operating Report (per Subsec-tion 5.4.1 of this EPP) brief descriptions, analyses, interpretations, andevaluations of such changes, tests and experiments.

• Activities are excluded from this requirement if all measurable nonradiological effects are confined to the on-site areas previously disturbed during site preparation and plant construction.

3.2 Changes

Required for Compliance with Other Environmental Regulations Changes in plant design or operation and performance of tests or experiments whicfi are required to achieve compliance with other Federal, State, or localenvironmental regulations are not subject to the requirements of Subsection 3.1 of this EPP.

---6 -4.0 Environmental Conditions

4.1 Unusual

or Important Environmental Events Any occurrence of an unusual or important event that indicates, or could result in, significant environmental impact causally related to plant operation shall be recorded and promptly reported to the NRC within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> by telephone,telegraph, or facsimile transmissions followed by a written report per Sub-section 5.4.2 of this EPP. The following are examples:

excessive bird impac-tion events, onsite plant or animal disease outbreaks, mortality or unusual occurrence of any species protected by the Endangered Species Act of 1973, fish kills, and an increase in nuisance organisms or conditions.

No routine monitoring programs are required to implement this condition.

4.2 Environmental

Monitoring

4.2.1 Cultural

Resources Section 4.3.6 of the FES-OL states, "No Archeological surveys have been undertaken in the PYNGS-to-Saouaro corridor because the construction of this line is not scheduled until 1984-1986.

When a final alignment for theSaguaro transmission line is selected, appropriate archeological surveys will X~ be undertaken and submitted for staff review and evaluation pursuant to condition 7.f. of the construction permit (FES-CP, p. iii)." The licensees should consult with the State Historic Preservation Office (SHPO) and the NRC in developing an appropriate cultural resource survey. A survey report will be submitted to NRC for review. Should the survey identify significant sites which may be eligible for the National Register of Historic Places, the licensees shall be required to provide the NRC with the information necessary to initiate a determination of eligibility request to the Keeper of the National Register.

The U.S. Department of Interior form entitled, "National Register of Historic Places Inventory-Nomination Form," should be filled out in detail with appropriate maps and other materials for each such site and returned to the NRC. Item 12 of the form need not be filled out. Thelicensees should refer to the Federal Register, September 21, 1977, Part 11, for detailed guidance. The NRC requests the licensees to take appropriate measures to protect such sites during the determination of eligibility process.Upon receipt and review of the information, the NRC will forward the materials to the Keeper for action. If the Keeper rules the sites are not eligible, the finding will be filed and this subsection of the EPP is fully satisfied with nofurther action required.If the Keeper rules that any of the sites are eligible for the National Register, the licensees are required to provide the NRC with the information with regard to completing a determination of effect which the operation and maintenance activities of the plant may have on the eligible sites. The licensees should follow the steps presented in 36 CFR 800.3 and 36 CFR 800.4 in developing the information. Upon receipt of the information, the NRC, in consultation withthe SHPO, will complete the determination of effect process. If the determi-nation results in a no effect determination as provided in 36 CFR 800.4(4)(B)(1), the documentation will be filed and this subsection of the EPP is fully satisfied with no further action required.

--7 -If the determination results in an effect determination, the licensees will be required to provide the NRC with information adequate to document the effect determination and an appropriate action program which the licensees have devel-oped in consultation with the SHPO and concurred in by the SHPO. Upon review of the program, the NRC will forward the documentation to the Advisory Council onHistoric Preservation (ACHP) for comment.After ACHP comment is received by NRC, the program will be revised, if necessary, to incorporate any comments provided by the ACHP. The licensees shall then proceed, in consultation with the SHPO, to implement the proposed program.Upon completion of the program, a report shall be submitted to the NRC which will include a description of the results of the program and the disposition of data recovered (if applicable).

Upon submittal of this report, this subsection of the EPP is fully satisfied with no further action required.4.2.2 Terrestrial Ecology MonitoringThe licensees will implement the Salt Deposition and Impact Monitoring Plan provided to NRC by letter dated May 17, 1985 from E. E. Van Brunt, Jr., Arizona Nuclear Power Project, to G. W. Knighton, U. S. Nuclear RegulatoryCommission. The purpose of the Plan is to assess the impacts of cooling towersalt drift on soils, native vegetation and agricultural crops in the PVNGS vicinity.The monitoring program shall commence by the onset of commercial operation of the first unit and continue for a minimum of three full years after the onset of operation of all three PVNGS Units or until such time that the licensees can demonstrate to the satisfication of the NRC that the objectives of the study have been fulfilled.

Annual monitoring reports shall be submitted tothe NRC for review.The licensees may not make changes in the procedures described in the documentwithout prior NRC approval unless the proposed changes do not affect the program objectives described in the introduction to the Monitoring Plan. For example, changes in the procedures, which affect sampling frequency, location,gear, or replication, can be made without prior NRC approval, but shall be reported to the NRC within 30 days after their implementation.

These reports shall describe the changes made, the reasons for making the changes, and a statement showing how continuity of the study will be affected.

Any modifications or chances of the initially approved program shall be governed by the need to maintain consistency with previously used procedures so that direct comparisons of data are technically valid. Such modifications or changes shall be justified and supported by adequate comparative sampling programs or studies demonstrating the comparability of results or which provide a basis for making adjustments that would permit direct comparisons.

The licensees shall maintain at the site, available for inspection, a copy of the Monitoring Plan with all revisions. 5.0 Administrative Procedures
