-Determination EG Paae 1 of 6 Description of change Changes to the REMP sampling program -Determination REMP Enhancements due to removal of Plant trip vulnerabilities related to off gas valve 2N62-F057 | |||
-Determination OG Changes to the minimum analysis frequency for the Containment Vent and Purge System -Determination PURGE 1 All pages All pages EG Added the ODCM revision effective date (Plant Manager approval date) to the header on all oaoes for revision 7. 2 Title Page Title Page EG Updated the ODCM effective date for revision 7. 3 Table of TOG EG Updated reference page numbering for the various sections, subsections, etc. Contents throughout the TOG as necessary. (TOG) 4 TOG, TOG, EG Added a dot leader to section 12.5.1 to be consistent with the balance of the TOG. oaoe 2 oaoe2 5 TOG, TOG, EG Updated section 5.1 with subsections 5.1 .4 and 5.1.5 that currently exist in the body of page 6 page 6 the ODCM. 6 1-1.1-6 1-1.1-6 EG Updated the ODCM Equation references within the 1 OCFR50, Appendix I Regulations (components 1.a. and 2.) and the Technical Specifications Regulations (component | |||
: 1. and 2.) sections to reference the appropriate ODCM Equations. | |||
7 1-12.4.1-2 1-12.4.1-2 PURGE Added superscript "k" in "SAMPLING FREQUENCY" column of row "A. CONTAINMENT VENT AND PURGE SYSTEM" to reference new note "k" on page I-12.4.1-6 regarding detailed guidance on performing the appropriate sampling, analyses, and purge calculations. | |||
8 1-12.4.1-2 1-12.4.1-2 PURGE Split the "MINIMUM ANALYSIS FREQUENCY" column for row "A. CONTAINMENT VENT AND PURGE SYSTEM" into two (2) parts-one (1) part for principal gamma emitters (noble gas samples) and one (1) part for tritium (H-3). The analysis frequency for principal gamma emitters remains unchanged | |||
-"Prior to each release Each Purge". However, the minimum analysis frequency for tritium was changed from "Prior to each release Each Purge" to "31 days" to be consistent with NUREG 1302. Regulatory Assurance has verified that there are no regulatory commitments that would be impacted by this change. Since tritium analyses add approximately 3-4 hours to the completion of purge calculations, this change will significantly reduce the time needed to complete purge calculations and will expedite a drywell entry, if required. | |||
The time required to complete purge calculations can be reduced from a total of 4 -6 hours to approximately 1 hour. Drywell tritium results obtained during the previous 31 days will be used to initially perform the purge calculations. | |||
Followino the completion of the 9 1-12.4.1-6 10 1-12.4.1-6 11 1-12.5.1-6 to 1-12.5.1-10 12 1-12.5.1-6 13 1-12.5.1-6 14 1-12.5.1-7 1-12.4.1-6 1-12.4.1-6 1-12.5.1-6 to 1-12.5.1-11 1-12.5.1-6 1-12.5.1-6 1-12.5.1-7 Determination identifier PURGE PURGE EG REMP REMP REMP Paae 2 of 6 Description of change actual ODCM required tritium purge sampling and analyses, the purge calculations will be updated. New note "k" on page 1-12.4.1-6 contains detailed guidance on performing the appropriate sampling, analyses, and purge calculations. | |||
Updated the wording in the last paragraph of Note h to be consistent with the change in the "MINIMUM ANALYSIS FREQUENCY" column in row "A. CONTAINMENT VENT AND PURGE SYSTEM" of Table R12.4.1-1. | |||
The original wording stated " ... both noble gas and tritium analyses must be completed | |||
... " The new wording states " ... both noble gas and tritium sampling along with the appropriate purge calculations must be completed | |||
... " The fact that the appropriate analyses are required is now understood based on the wording of the sentence. | |||
That is, the appropriate analyses must be completed in order to perform the purge calculations. | |||
Added notes "j" and "k". Note "j" states: "Not used." This was done to avoid future confusion between "j" and "i" when viewing the ODCM where poor document resolution may exist. Note "k" adds detailed guidance to perform the appropriate sampling, analyses, and purge calculations. Updated the page numbering on all pages in Table R12.5.1-1 from "(Page X of 5)" to "(Page X of 6)" due to new page 5 being added to the Table (Page 1-12.5.1-10). In the "SAMPLING AND COLLECTION FREQUENCY" column for the airborne radioiodine and particulates exposure pathway (ODCM Table R12.5.1-1, Section 1.), updated the particulate sample collection frequency from " ... once per 7 days ... " to " ... weekly ... " to be consistent with the current ODCM Table 6-1 and NUREG-1302. | |||
Also, updated radioiodine canister collection frequency from " ... once per 14 days." to " ... weekly'' to be consistent with NUREG-1302 Table 3.12-1 as identified by the NRC (Reference ATI 2541452-02).

The defined terms of this section appear in capitalized type and are applicable throughout these Offsite Dose Calculation Manual (ODCM) Controls and Bases. ACTION CHANNEL CALIBRATION CHANNEL CHECK CHANNEL FUNCTIONAL TEST Definition ACTION shall be that part of a control that prescribes remedial measures required under designated conditions. | |||
A CHANNEL CALIBRATION shall be the adjustment, as necessary, of the channel output such that it responds within the necessary range and accuracy to known values of the parameter that the channel monitors. | |||
The CHANNEL CALIBRATION shall encompass the entire channel, including the required sensor, alarm, display, and trip functions, and shall include the CHANNEL FUNCTIONAL TEST. Calibration of instrument channels with resistance temperature detector (RTD) or thermocouple sensors may consist of an in-place qualitative assessment of sensor behavior and normal calibration of the remaining adjustable devices in the channel. The CHANNEL CALIBRATION may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is calibrated. | |||
For specific calibration requirements refer to surveillance requirements section for the applicable instrumentation. | |||
A CHANNEL CHECK shall be a qualitative assessment, by observation, of channel behavior during operation. | |||
This determination shall include, where possible, comparison of the channel indication and status to other indications or status derived from independent instrument channels measuring the same parameter. | |||
A CHANNEL FUNCTIONAL TEST shall be the injection of a simulated or actual signal into the channel as close to the sensor as practicable to verify OPERABILITY, including required alarm, interlock, display, and trip functions, and channel failure trips. The CHANNEL FUNCTIONAL TEST may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is tested. (continued) | |||

CONTINUOUS SAMPLING DOSE EQUIVALENT 1-131 GASEOUS RADWASTE TREATMENT SYSTEM MEMBERS OF THE PUBLIC MODE OCCUPATIONAL DOSE Uninterrupted sampling with the exception of sampling interruptions of short duration for required surveillances. | |||
That concentration of 1-131 (microcuries/gram) that alone would produce the same thyroid dose as the quantity and isotopic mixture of 1-131, 1-132, 1-133, 1-134, and 1-135 actually present. The thyroid dose conversion factors used for this calculation shall be those listed in Table Ill of TIO -14844, AEC, 1962, "Calculation of Distance Factors for Power and Test Reactor Sites"; Table E-7 of Regulatory Guide 1.109, Rev. 1, NRC, 1977; or ICRP 30, Supplement to Part 1, pages 192-212, Table titled, "Committed Dose Equivalent in Target Organs or Tissues per Intake of Unit Activity." Any system designed and installed to reduce radioactive gaseous effluents by collecting primary coolant system offgases from the primary system and providing for delay or holdup for the purpose of reducing the total radioactivity prior to release to the environment. | |||
Any individual, except when that individual is receiving an occupational dose. A MODE shall correspond to any one inclusive combination of mode switch position, average reactor coolant temperature, and reactor vessel head closure bolt tensioning specified in Technical Specifications with fuel in the reactor vessel. The dose received by an individual in the course of employment in which the individual's assigned duties involve exposure to radiation and/or to radioactive material from licensed and unlicensed sources of radiation, whether in the possession of the licensee or other person. Occupational dose does not include dose from background radiation, as a patient from medical practices, from voluntary participation in medical research programs, or as a member of the public.

===1.2 Logical=== | |||
Connectors PURPOSE BACKGROUND EXAMPLES The purpose of this section is to explain the meaning of logical connectors. | |||
Logical connectors are used in ODCM to discriminate between, and yet connect, discrete Conditions, Required Actions, Completion Times, Surveillances, and Frequencies. | |||
The only logical connectors that appear in ODCM are AND and OR. The physical arrangement of these connectors constitutes logical conventions with specific meanings. | |||
Several levels of logic may be used to state Required Actions. These levels are identified by the placement | |||
{or nesting) of the logical connectors and by the number assigned to each Required Action. The first level of logic is identified by the first digit of the number assigned to a Required Action and the placement of the logical connector in the first level of nesting {i.e., left justified with the number of the Required Action). The successive levels of logic are identified by additional digits of the Required Action number and by successive indentations of the logical connectors. | |||
When logical connectors are used to state a Condition, Completion Time, Surveillance, or Frequency, only the first level of logic is used, and the logical connector is left justified with the statement of the Condition, Completion Time, Surveillance, or Frequency. | |||
The following examples illustrate the use of logical connectors. (continued) | |||
Page 1-1.2-1 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.2 Logical Connectors EXAMPLES (continued} | |||
EXAMPLE 1.2-1 ACTIONS CONDITION A. Control not met. REQUIRED ACTION A.1 Verify ... A.2 Restore ... COMPLETION TIME In this example, the logical connector AND is used to indicate that, when in Condition A, both Required Actions A.1 and A.2 must be completed. (continued) | |||

EXAMPLE 1.2-2 ACTIONS CONDITION REQUIRED ACTION COMPLETION TIME A. Control not met. A.1 Trip ... OR A.2.1 Verify ... AND A.2.2.1 Reduce ... OR A.2.2.2 Perform ... OR A.3 Align This example represents a more complicated use of logical connectors. | |||
Required Actions A.1, A.2 and A.3 are alternate choices, only one of which must be performed as indicated by the use of the logical connector OR and the left justified placement. | |||
Any one of these three Action may be chosen. If A.2 is chose, then both A.2.1 and A.2.2 must be performed as indicated by the logical connector AND. Required Action A.2.2 is met by performing A.2.2.1 or A.2.2.2. The indented position of the logical connector OR indicates that A.2.2.1 and A.2.2.2 are alternative choices, only one of which must be performed. | |||

===1.3 Completion=== | |||
Times PURPOSE BACKGROUND DESCRIPTION The purpose of this section is to establish the Completion Time convention and to provide guidance for its use. ODCM Radiological Effluent Controls (RECs) specify minimum requirements for ensuring safe operation of the unit. The ACTIONS associated with a REC state Conditions that typically describe the ways in which the requirements of the REC can fail to be met. Specified with each stated Condition are Required Action(s) and Completion Times. 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 Condition unless otherwise specified, providing the unit is in a MODE or specified condition stated in the Applicability of the REC. Required Actions must be completed prior to the expiration of the specified Completion Time. An ACTIONS Condition remains in effect and the Required Actions apply until the Condition no longer exists or the unit is not within the REC Applicability. | |||
If situations are discovered that require entry into more than one Condition at a time within a single REC (multiple Conditions), the Required Actions for each Condition must be performed within the associated Completion Time. When in multiple Conditions, separate Completion Times are tracked for each Condition starting from the time of discovery of the situation that required entry into the Condition. | |||
Once a Condition has been entered, subsequent divisions, subsystem, 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 apply to each additional failure, with Completion Times based on initial entry into the Condition. (continued) | |||
Page 1-1.3-1 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.3 Completion Times DESCRIPTION (continued) | |||
EXAMPLES However, when a subsequent division, subsystem, component, 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 Time extension, two criteria must first be met. The subsequent inoperability: | |||
: a. Must exist concurrent with the first inoperability; and b. Must remain inoperable or not within limits after the first inoperability is resolved. | |||
The total Completion Time allowed for completing a Required Action to address the subsequent inoperability shall be limited to the more restrictive of either: a. The stated Completion Time , as measured from the initial entry into the Condition, plus an additional 24 hours; or b. The stated Completion Time as measured from discovery of the subsequent inoperability. | |||
The above Completion Time extension does not apply to those RECs that have exceptions that allow completely separate re-entry into the Condition (for each division, subsystem, component, or variable expressed in the Condition) and separate tracking of Completion Times based on this entry. These exceptions are stated in individual RECs. The above Completion Time extension does not apply to a Completion Time with a modified "time zero." This modified "time zero" may be expressed as a repetitive time (i.e., "once per 8 hours," where the Completion Time is referenced from a previous completion of the Required Action versus the time of Condition entry) or as a time modified by the phrase "from discovery | |||
... " Example 1.3-3 illustrates one use of this type of Completion Time. The 10 day Completion Time specified for Condition A and B in Example 1.3-3 may not be extended. | |||
The following examples illustrate the use of Completion Times with different types of Conditions and changing Conditions. | |||

EXAMPLE 1.3-1 ACTIONS CONDITION REQUIRED ACTION B. Required Action and B.1 Be in MODE 3. associated Completion Time not met. B.2 Be in MODE 4. COMPLETION TIME 12 hours 36 hours Condition B has two Required Actions. Each Required Action has its own separate Completion Time. Each Completion Time is referenced to the time that Condition B is entered. The Required Actions of Condition Bare in to be in MODE 3 within 12 hours AND in MODE 4 within 36 hours. A total of 12 hours is allowed for reaching MODE 3 and a total of 36 hours (not 48 hours) is allowed for reaching MODE 4 from the time that Condition B was entered. If MODE 3 is reached within 6 hours, the time allowed for reaching MODE 4 is the next 30 hours because the total time allowed for reaching Mode 4 is 36 hours. If Condition B is entered while in MODE 3, the time allowed for reaching MODE 4 is the next 36 hours. (continued) | |||

EXAMPLE 1.3-2 ACTIONS CONDITION REQUIRED ACTION COMPLETION TIME A. One monitor A.1 Restore monitor to 7 days inoperable. | |||
OPERABLE status. B. Required Action and B.1 Be in MODE 3. 12 hours associated Completion Time not met. AND B.2 Be in MODE4. 36 hours When a monitor is declared inoperable, Condition A is entered. If the monitor is not restored to OPERABLE status within 7 days, Condition B is also entered and the Completion Time clocks for Required Action B.1 and 8.2 start. If the inoperable monitor is restored to OPERABLE status after Condition B is entered, Condition A and B are exited, and therefore, the Required Actions of Condition B may be terminated. | |||
When a monitor pump is declared inoperable while the first monitor is still inoperable, Condition A is not re-entered for the second monitor. REC 12.0.3 is entered, since the ACTIONS do not include a Condition from more than one inoperable monitor. The Completion Time clock for Condition A does not stop after REC 12.0.3 is entered, but continues to be tracked from the time Condition A was initially entered. While in REC 12.0.3, if one of the inoperable monitors is restored to OPERABLE status and the Completion Time for Condition A has not expired, REC 12.0.3 may be exited and operation continued in accordance with Condition A. (continued) | |||

While in REC 12.0.3, if one of the inoperable monitors is restored to OPERABLE status and the Completion Time for Condition A has expired, REC 12.0.3 may be exited and operation continued in accordance with Condition B. The Completion Time for Condition B is tracked from the time the Condition A Completion Time expired. On restoring one of the monitors to OPERABLE status, the Condition A Completion Time is not reset, but continues from the time the first monitor was declared inoperable. | |||
This Completion Time may be extended if the monitor restored to OPERABLE status was the first inoperable monitor. A 24 hour extension to the stated 7 days is allowed, provided this does not result in the second monitor being inoperable for > 7 days. (continued) | |||

AND 10 days from discovery of failure to meet the Control Restore Function Y 72 hours subsystem to OPERABLE status. AND 10 days from discovery to meet Control Restore Function X 72 hours subsystem to OPERABLE status. 72 hours Restore Function Y subsystem to OPERABLE status. (continued) | |||
Page 1-1.3-6 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.3 Completion Times EXAMPLES EXAMPLE 1.3-3 (continued) | |||
When one Function X subsystem and one Function Y subsystem are inoperable, Condition A and Condition B are concurrently applicable. | |||
The Completion Times for Condition A and Condition B are tracked separately for each subsystem, starting from the time each subsystem was declared inoperable and the Condition was entered. A separate Completion Time is established for Condition C and tracked from the time the second subsystem 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 Time, Conditions Band Care exited. If the Completion Time for Required Action A.1 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 subsystem 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 Time measured from the time it was discovered the REC 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 REC. The separate Completion Time modified by the phrase "from discovery of failure to meet the Control" is designed to prevent indefinite continued operation while not meeting the REC. This Completion Time allows for an exception to the normal "time zero" for beginning the Completion Time "clock." In this instance, the Completion Time "time zero" is specified as commencing at the time the associated Condition was entered. (continued) | |||

instruments(s) to OPERABLE status. B. Required Action and B.1 Be in MODE3. 12 hours associated Completion Time not met. AND 36 hours B.2 Be in MODE4. A single Completion Time is used for any number of instruments inoperable at the same time. The Completion Time associated with Condition A is based on the initial entry into Condition A and is not tracked on a per instrument basis. Declaring subsequent instruments inoperable, while Condition A is still in effect, does not trigger the tracking of separate Completion Times. | |||
Once one of the instruments has been restored to OPERABLE status, the Condition A Completion Time is not reset, but continues from the time the first instrument was declared inoperable. | |||
The Completion Time may be extended if the instrument restored to OPERABLE status was the first inoperable instrument. | |||
The Condition A Completion Time may be extended for up to 4 hours provided this does not result in any subsequent instrument being inoperable for > 4 hours. If the Completion Time of 4 hours (plus the extension) expires while one or more instruments are still inoperable, Condition B is entered. (continued) | |||

EXAMPLE 1.3-5 ACTIONS ---------------------------NOTE------------------------------ | |||
Separate Condition entry is allowed for each inoperable instrument. | |||
CONDITION REQUIRED ACTION COMPLETION TIME A. One or more instruments A.1 Restore 4 hours inoperable. | |||
instrument(s) to OPERABLE status. B. Required Action and B.1 Be in MODE 3. 12 hours associated Completion Time not met. AND 36 hours B.2 Bein MODE4. The Note above the ACTIONS Table is a method of modifying how the Completion Time is tracked. If this method of modifying how the Completion Time is tracked was applicable only to a specific Condition, the Note would appear in that Condition rather than at the top of the ACTIONS Table. The Note allows Condition A to be entered separately for each inoperable instrument, and Completion Times tracked on a per instrument basis. When an instrument is declared inoperable, Condition A is entered and its Completion Time starts. If subsequent instruments are declared inoperable, Condition A is entered for each instrument and separate Completion Times start and are tracked for each instrument. | |||
If the Completion Time associated with an instrument in Condition A expires, Condition B is entered for that instrument. | |||
If the Completion Times associated with subsequent instruments in Condition A expire, Condition B is entered separately for each instrument and separate Completion Times start and are tracked for each instrument. | |||
If a instrument that caused entry into Condition B is restored to OPERABLE status, Condition B is exited for that instrument. | |||
Since the Note in this example allows multiple Condition entry and tracking of separate Completion Times, Completion Time extensions do not apply. (continued) | |||

OR Reduce THERMAL POWER to 8 hours RTP. B. Required Action and B.1 Be in MODE 3. 12 hours associated Completion Time not met. Entry into Condition A offers a choice between Required Action A.1 or A.2. Required Action A.1 has a "once per" Completion Time, which qualifies for the 25% extension, per RSR 12.0.2 to each performance after the initial performance. | |||
The initial 8 hour interval of Required Action A.1 begins when Condition A is entered and the initial performance of Required Action A.1 must be completed within the first 8 hour interval. | |||
If Required Action A.1 is followed and the Required Action is not met within the Completion Time (plus the extension allowed by RSR 12.0.2), Condition B is entered. If Required Action A.2 is followed and the Completion Time of 8 hours is not met, Condition B is entered. If after entry into Condition B, Required Action A.1 or A.2 is met, Condition B is exited and operation may then continue in Condition A. (continued) | |||

AND B.2 Be in MODE4. 36 hours Required Action A.1 has two Completion Times. The 1 hour Completion Time begins at the time the Condition is entered and each "Once per 8 hours thereafter" interval begins upon performance of Required Action A.1. If after Condition A is entered, Required Action A.1 is not met within either the initial 1 hour or any subsequent 8 hour interval from the previous performance (plus the extension allowed by RSR 12.0.2), Condition B is entered. The Completion Time clock for Condition A does not stop after Condition Bis entered, but continues from the time Condition A was initially entered. If Required Action A.1 is met after Condition B is entered, Condition B is exited and operation may continue in accordance with Condition A, provided the Completion Time for Required Action A.2 has not expired. When "Immediately" is used as a Completion Time, the Required Action should be pursued without delay and in a controlled manner.

===1.4 Frequency=== | |||
PURPOSE DESCRIPTION The purpose of this section is to define the proper use and application of Frequency requirements. | |||
Each ODCM Radiological Effluent Surveillance Requirement (RSR) has a specified Frequency in which the Surveillance must be met in order to meet the associated ODCM REC. An understanding of the correct application of the specified Frequency is necessary for compliance with the RSR. The "specified Frequency" is referred to throughout this section and each of the Requirements of Section 12.0, ODCM Surveillance Requirement (RSR) Applicability. The "specified Frequency" consists of the requirements of the Frequency column of each RSR, as well as certain Notes in the Surveillance column that modify performance requirements. | |||
Sometimes special situations dictate when the requirements of a Surveillance are to be met. They are "otherwise stated" conditions allowed by RSR 12.0.1. They may be stated as clarifying Notes in the Surveillance, as part of the Surveillance, or both. Example 1.4-4 discusses these special situations. | |||
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 REC is within its Applicability, represent potential RSR 12.0.4 conflicts. | |||
To avoid these conflicts, the RSR (i.e., the Surveillance or the Frequency) is stated such that it is only "required" when it can be and should be performed. | |||
With a RSR satisfied, RSR 12.0.4 imposes no restriction. | |||
The use of "met" or "performed" in these instances conveys specified meanings. | |||
A Surveillance is "met" only when the acceptance criteria are satisfied. | |||
Known failure of the requirements of a Surveillance, even without a Surveillance specifically being "performed," constitutes a Surveillance not "met." "Performance" refers only to the requirement to (continued) | |||

===1.4 Frequency=== | |||
DESCRIPTION (continued) | |||
EXAMPLES specifically determine the ability to meet the acceptance criteria. | |||
RSR 12.0.4 restrictions would not apply if both the following conditions are satisfied: | |||
: a. The Surveillance is not required to be performed; and b. The Surveillance is not required to be met or, even if required to be met, is not known to be failed. The following examples illustrate the various ways that Frequencies are specified. | |||
In these examples, the Applicability of the REC (REC not shown) is MODES 1, 2, and 3. EXAMPLE 1.4-1 SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY Perform CHANNEL CHECK 12 hours Example 1.4-1 contains the type of RSR most often encountered in the ODCM. The Frequency specifies an interval (12 hours) during which the associated Surveillance must be performed at least one time. Performance of the Surveillance initiates the subsequent interval. | |||
Although the Frequency is stated as 12 hours, an extension of the time interval to 1.25 times the interval specified in the Frequency is allowed by RSR 12.0.2 for operational flexibility. The measurement of this interval continues at all times, event when the RSR is not required to be met per RSR 12.0.1 (such as when the equipment is inoperable, a variable is outside specified limits, or the unit is outside the Applicability of the REC). If the interval specified by RSR 12.0.2 is exceeded while the unit is in a MODE or other specified condition in the Applicability of the REC, (continued) | |||
Page 1-1.4-2 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.0 USE AND APPLICATION 1.4 Frequency EXAMPLES EXAMPLE 1.4-1 (continued) and the performance of the Surveillance is not otherwise modified (refer to Examples 1.4-3 and 1.4-4 ), then RSR 12.0.3 becomes applicable. | |||
If the interval as specified by RSR 12.0.2 is exceeded while the unit is not in a MODE or other specified condition in the Applicability of the REC for which performance of the RSR is required, the Surveillance must be performed within the Frequency requirements of RSR 12.0.2 prior to entry into the MODE or other specified condition. | |||
Failure to do so would result in a violation of RSR 12.0.4. EXAMPLE 1.4-2 SURVEILLANCE REQUIREMENTS SURVEILLANCE Verify flow is within limits. FREQUENCY Once within 12 hours after.::, 25% RTP 24 hours thereafter Example 1.4-2 has two Frequencies. | |||
The first is a one time performance Frequency, and the second is of the type shown in Example 1.4-1. The logical connector "AND" indicates that both Frequency requirements must be met. Each time reactor power is increased from a power level < 25% RTP to .::, 25% RTP, the Surveillance must be performed within 12 hours. (continued) | |||
Page 1-1.4-3 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.0 USE AND APPLICATION | |||
===1.4 Frequency=== | |||
EXAMPLES EXAMPLE 1.4-2 (continued) | |||
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 RSR 12.0.2. "Thereafter'' | |||
indicates future performances must be established per RSR 12.0.2, 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. EXAMPLE 1.4-2 SURVEILLANCE REQUIREMENTS SURVEILLANCE | |||
-----------------NOTE------------- | |||
Not required to be performed until 12 hours 25% RTP. Perform channel adjustment. | |||
FREQUENCY 7 days 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 hours after power reaches 25% RTP to perform the Surveillance. | |||
The Surveillance is still considered to be within the "specified Frequency." Therefore, if the Surveillance were not performed within the 7 day interval (plus the extension allowed by RSR 12.0.2), but operation was< 25% RTP, (continued) | |||
Page 1-1.4-4 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.0 USE AND APPLICATION | |||
===1.4 Frequency=== | |||
EXAMPLES EXAMPLE 1.4-3 (continued) it would not constitute a failure of the RSR or failure to meet the REC. Also, no violation of RSR 12.0.4 occurs when changing MODES, even with the 7 day Frequency not met, provided operation does not exceed 12 hours with power ?_25% RTP. Once the unit reaches 25% RTP, 12 hours would be allowed for completing the Surveillance. | |||
If the Surveillance were not performed within this 12 hour interval, there would then be a failure to perform a Surveillance within the specified Frequency, and the provisions of RSR 12.0.3 would apply. EXAMPLE 1.4-2 SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY | |||
--------------NOTE---------------- | |||
Only required to be met in MODE 1. Verify leakage rates are within limits. 24 hours Example 1.4-4 specifies that the requirements of this Surveillance do not have to be met until the unit is in MODE 1. The interval measurement for the Frequency of this Surveillance continues at all times, as described in Example 1.4-1. However, the Note constitutes an "otherwise stated" exception to the Applicability of this Surveillance. | |||
Therefore, if the Surveillance were not performed within the 24 hour interval (plus the extension allowed by RSR 12.0.2), but the unit was not in MODE 1, there would be no failure of the RSR nor failure to meet the REC. Therefore, no violation of RSR 12.0.4 occurs when changing MODES, even with the 24 hour Frequency exceeded, provided the MODE change was not made into MODE 1. Prior to entering MODE 1 (assuming again that the 24 hour Frequency were not met), RSR 12.0.4 would require satisfying the RSR. Page 1-1.4-5 1.0 USE AND APPLICATION 1.5 REC and RSR Implementation CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls The ODCM provides those limitations upon plant operations which are part of the licensing basis for the station but do not meet the criteria for continued inclusion in the Technical Specifications. | |||
It also provides information which supplements the Technical Specifications by implementing the requirements of Technical Specification Sections 5.5.1, 5.5.4, 5.6.2, and 5.6.3. RECs and RSRs are implemented the same as Technical Specifications (see 12.0 Applicability). | |||
However, RECs and RSRs are treated as plant procedures and are not part of the Technical Specifications. | |||
Therefore the following exceptions apply: a. Violations of the Action or Surveillance requirements in a REC are not reportable as conditions prohibited by, or deviations from, the Technical Specifications per 10 CFR 50.72or10 CFR 50.73. b. Power reduction or plant shutdowns required to comply with the Actions of a REC are not reportable per 10 CFR 50.72or10 CFR 50.73. Page 1-1.5-1 | |||

-Determination EG Paae 1 of 6 Description of change Changes to the REMP sampling program -Determination REMP Enhancements due to removal of Plant trip vulnerabilities related to off gas valve 2N62-F057
-Determination OG Changes to the minimum analysis frequency for the Containment Vent and Purge System -Determination PURGE 1 All pages All pages EG Added the ODCM revision effective date (Plant Manager approval date) to the header on all oaoes for revision 7. 2 Title Page Title Page EG Updated the ODCM effective date for revision 7. 3 Table of TOG EG Updated reference page numbering for the various sections, subsections, etc. Contents throughout the TOG as necessary. (TOG) 4 TOG, TOG, EG Added a dot leader to section 12.5.1 to be consistent with the balance of the TOG. oaoe 2 oaoe2 5 TOG, TOG, EG Updated section 5.1 with subsections 5.1 .4 and 5.1.5 that currently exist in the body of page 6 page 6 the ODCM. 6 1-1.1-6 1-1.1-6 EG Updated the ODCM Equation references within the 1 OCFR50, Appendix I Regulations (components 1.a. and 2.) and the Technical Specifications Regulations (component
- 1. and 2.) sections to reference the appropriate ODCM Equations.
7 1-12.4.1-2 1-12.4.1-2 PURGE Added superscript "k" in "SAMPLING FREQUENCY" column of row "A. CONTAINMENT VENT AND PURGE SYSTEM" to reference new note "k" on page I-12.4.1-6 regarding detailed guidance on performing the appropriate sampling, analyses, and purge calculations.
8 1-12.4.1-2 1-12.4.1-2 PURGE Split the "MINIMUM ANALYSIS FREQUENCY" column for row "A. CONTAINMENT VENT AND PURGE SYSTEM" into two (2) parts-one (1) part for principal gamma emitters (noble gas samples) and one (1) part for tritium (H-3). The analysis frequency for principal gamma emitters remains unchanged
-"Prior to each release Each Purge". However, the minimum analysis frequency for tritium was changed from "Prior to each release Each Purge" to "31 days" to be consistent with NUREG 1302. Regulatory Assurance has verified that there are no regulatory commitments that would be impacted by this change. Since tritium analyses add approximately 3-4 hours to the completion of purge calculations, this change will significantly reduce the time needed to complete purge calculations and will expedite a drywell entry, if required.
The time required to complete purge calculations can be reduced from a total of 4 -6 hours to approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. Drywell tritium results obtained during the previous 31 days will be used to initially perform the purge calculations.

New note "k" on page 1-12.4.1-6 contains detailed guidance on performing the appropriate sampling, analyses, and purge calculations.
Updated the wording in the last paragraph of Note h to be consistent with the change in the "MINIMUM ANALYSIS FREQUENCY" column in row "A. CONTAINMENT VENT AND PURGE SYSTEM" of Table R12.4.1-1.
The original wording stated " ... both noble gas and tritium analyses must be completed
... " The new wording states " ... both noble gas and tritium sampling along with the appropriate purge calculations must be completed
... " The fact that the appropriate analyses are required is now understood based on the wording of the sentence.
That is, the appropriate analyses must be completed in order to perform the purge calculations.
Added notes "j" and "k". Note "j" states: "Not used." This was done to avoid future confusion between "j" and "i" when viewing the ODCM where poor document resolution may exist. Note "k" adds detailed guidance to perform the appropriate sampling, analyses, and purge calculations. Updated the page numbering on all pages in Table R12.5.1-1 from "(Page X of 5)" to "(Page X of 6)" due to new page 5 being added to the Table (Page 1-12.5.1-10). In the "SAMPLING AND COLLECTION FREQUENCY" column for the airborne radioiodine and particulates exposure pathway (ODCM Table R12.5.1-1, Section 1.), updated the particulate sample collection frequency from " ... once per 7 days ...

1.1 DEFINITIONS
The defined terms of this section appear in capitalized type and are applicable throughout these Offsite Dose Calculation Manual (ODCM) Controls and Bases. ACTION CHANNEL CALIBRATION CHANNEL CHECK CHANNEL FUNCTIONAL TEST Definition ACTION shall be that part of a control that prescribes remedial measures required under designated conditions.
A CHANNEL CALIBRATION shall be the adjustment, as necessary, of the channel output such that it responds within the necessary range and accuracy to known values of the parameter that the channel monitors.
The CHANNEL CALIBRATION shall encompass the entire channel, including the required sensor, alarm, display, and trip functions, and shall include the CHANNEL FUNCTIONAL TEST. Calibration of instrument channels with resistance temperature detector (RTD) or thermocouple sensors may consist of an in-place qualitative assessment of sensor behavior and normal calibration of the remaining adjustable devices in the channel. The CHANNEL CALIBRATION may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is calibrated.
For specific calibration requirements refer to surveillance requirements section for the applicable instrumentation.
A CHANNEL CHECK shall be a qualitative assessment, by observation, of channel behavior during operation.
This determination shall include, where possible, comparison of the channel indication and status to other indications or status derived from independent instrument channels measuring the same parameter.
A CHANNEL FUNCTIONAL TEST shall be the injection of a simulated or actual signal into the channel as close to the sensor as practicable to verify OPERABILITY, including required alarm, interlock, display, and trip functions, and channel failure trips. The CHANNEL FUNCTIONAL TEST may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is tested. (continued)

CONTINUOUS SAMPLING DOSE EQUIVALENT 1-131 GASEOUS RADWASTE TREATMENT SYSTEM MEMBERS OF THE PUBLIC MODE OCCUPATIONAL DOSE Uninterrupted sampling with the exception of sampling interruptions of short duration for required surveillances.
That concentration of 1-131 (microcuries/gram) that alone would produce the same thyroid dose as the quantity and isotopic mixture of 1-131, 1-132, 1-133, 1-134, and 1-135 actually present. The thyroid dose conversion factors used for this calculation shall be those listed in Table Ill of TIO -14844, AEC, 1962, "Calculation of Distance Factors for Power and Test Reactor Sites"; Table E-7 of Regulatory Guide 1.109, Rev. 1, NRC, 1977; or ICRP 30, Supplement to Part 1, pages 192-212, Table titled, "Committed Dose Equivalent in Target Organs or Tissues per Intake of Unit Activity." Any system designed and installed to reduce radioactive gaseous effluents by collecting primary coolant system offgases from the primary system and providing for delay or holdup for the purpose of reducing the total radioactivity prior to release to the environment.
Any individual, except when that individual is receiving an occupational dose. A MODE shall correspond to any one inclusive combination of mode switch position, average reactor coolant temperature, and reactor vessel head closure bolt tensioning specified in Technical Specifications with fuel in the reactor vessel. The dose received by an individual in the course of employment in which the individual's assigned duties involve exposure to radiation and/or to radioactive material from licensed and unlicensed sources of radiation, whether in the possession of the licensee or other person. Occupational dose does not include dose from background radiation, as a patient from medical practices, from voluntary participation in medical research programs, or as a member of the public.

1.2 Logical
Connectors PURPOSE BACKGROUND EXAMPLES The purpose of this section is to explain the meaning of logical connectors.
Logical connectors are used in ODCM to discriminate between, and yet connect, discrete Conditions, Required Actions, Completion Times, Surveillances, and Frequencies.
The only logical connectors that appear in ODCM are AND and OR. The physical arrangement of these connectors constitutes logical conventions with specific meanings.
Several levels of logic may be used to state Required Actions. These levels are identified by the placement
{or nesting) of the logical connectors and by the number assigned to each Required Action. The first level of logic is identified by the first digit of the number assigned to a Required Action and the placement of the logical connector in the first level of nesting {i.e., left justified with the number of the Required Action). The successive levels of logic are identified by additional digits of the Required Action number and by successive indentations of the logical connectors.
When logical connectors are used to state a Condition, Completion Time, Surveillance, or Frequency, only the first level of logic is used, and the logical connector is left justified with the statement of the Condition, Completion Time, Surveillance, or Frequency.
The following examples illustrate the use of logical connectors. (continued)
Page 1-1.2-1 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.2 Logical Connectors EXAMPLES (continued}
EXAMPLE 1.2-1 ACTIONS CONDITION A. Control not met. REQUIRED ACTION A.1 Verify ... A.2 Restore ... COMPLETION TIME In this example, the logical connector AND is used to indicate that, when in Condition A, both Required Actions A.1 and A.2 must be completed. (continued)

EXAMPLE 1.2-2 ACTIONS CONDITION REQUIRED ACTION COMPLETION TIME A. Control not met. A.1 Trip ... OR A.2.1 Verify ... AND A.2.2.1 Reduce ... OR A.2.2.2 Perform ... OR A.3 Align This example represents a more complicated use of logical connectors.
Required Actions A.1, A.2 and A.3 are alternate choices, only one of which must be performed as indicated by the use of the logical connector OR and the left justified placement.
Any one of these three Action may be chosen. If A.2 is chose, then both A.2.1 and A.2.2 must be performed as indicated by the logical connector AND. Required Action A.2.2 is met by performing A.2.2.1 or A.2.2.2. The indented position of the logical connector OR indicates that A.2.2.1 and A.2.2.2 are alternative choices, only one of which must be performed.

1.3 Completion
Times PURPOSE BACKGROUND DESCRIPTION The purpose of this section is to establish the Completion Time convention and to provide guidance for its use. ODCM Radiological Effluent Controls (RECs) specify minimum requirements for ensuring safe operation of the unit. The ACTIONS associated with a REC state Conditions that typically describe the ways in which the requirements of the REC can fail to be met. Specified with each stated Condition are Required Action(s) and Completion Times. 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 Condition unless otherwise specified, providing the unit is in a MODE or specified condition stated in the Applicability of the REC. Required Actions must be completed prior to the expiration of the specified Completion Time. An ACTIONS Condition remains in effect and the Required Actions apply until the Condition no longer exists or the unit is not within the REC Applicability.
If situations are discovered that require entry into more than one Condition at a time within a single REC (multiple Conditions), the Required Actions for each Condition must be performed within the associated Completion Time. When in multiple Conditions, separate Completion Times are tracked for each Condition starting from the time of discovery of the situation that required entry into the Condition.
Once a Condition has been entered, subsequent divisions, subsystem, 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 apply to each additional failure, with Completion Times based on initial entry into the Condition. (continued)
Page 1-1.3-1 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.3 Completion Times DESCRIPTION (continued)
EXAMPLES However, when a subsequent division, subsystem, component, 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 Time extension, two criteria must first be met. The subsequent inoperability:
- a. Must exist concurrent with the first inoperability; and b. Must remain inoperable or not within limits after the first inoperability is resolved.
The total Completion Time allowed for completing a Required Action to address the subsequent inoperability shall be limited to the more restrictive of either: a. The stated Completion Time , as measured from the initial entry into the Condition, plus an additional 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; or b. The stated Completion Time as measured from discovery of the subsequent inoperability.
The above Completion Time extension does not apply to those RECs that have exceptions that allow completely separate re-entry into the Condition (for each division, subsystem, component, or variable expressed in the Condition) and separate tracking of Completion Times based on this entry. These exceptions are stated in individual RECs. The above Completion Time extension does not apply to a Completion Time with a modified "time zero." This modified "time zero" may be expressed as a repetitive time (i.e., "once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />," where the Completion Time is referenced from a previous completion of the Required Action versus the time of Condition entry) or as a time modified by the phrase "from discovery
... " Example 1.3-3 illustrates one use of this type of Completion Time. The 10 day Completion Time specified for Condition A and B in Example 1.3-3 may not be extended.
The following examples illustrate the use of Completion Times with different types of Conditions and changing Conditions.

If the monitor is not restored to OPERABLE status within 7 days, Condition B is also entered and the Completion Time clocks for Required Action B.1 and 8.2 start. If the inoperable monitor is restored to OPERABLE status after Condition B is entered, Condition A and B are exited, and therefore, the Required Actions of Condition B may be terminated.
When a monitor pump is declared inoperable while the first monitor is still inoperable, Condition A is not re-entered for the second monitor. REC 12.0.3 is entered, since the ACTIONS do not include a Condition from more than one inoperable monitor. The Completion Time clock for Condition A does not stop after REC 12.0.3 is entered, but continues to be tracked from the time Condition A was initially entered. While in REC 12.0.3, if one of the inoperable monitors is restored to OPERABLE status and the Completion Time for Condition A has not expired, REC 12.0.3 may be exited and operation continued in accordance with Condition A.

(continued)
Page 1-1.3-6 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.3 Completion Times EXAMPLES EXAMPLE 1.3-3 (continued)
When one Function X subsystem and one Function Y subsystem are inoperable, Condition A and Condition B are concurrently applicable.
The Completion Times for Condition A and Condition B are tracked separately for each subsystem, starting from the time each subsystem was declared inoperable and the Condition was entered. A separate Completion Time is established for Condition C and tracked from the time the second subsystem 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 Time, Conditions Band Care exited. If the Completion Time for Required Action A.1 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 subsystem 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 Time measured from the time it was discovered the REC 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 REC. The separate Completion Time modified by the phrase "from discovery of failure to meet the Control" is designed to prevent indefinite continued operation while not meeting the REC. This Completion Time allows for an exception to the normal "time zero" for beginning the Completion Time "clock." In this instance, the Completion Time "time zero" is specified as commencing at the time the associated Condition was entered. (continued)

A single Completion Time is used for any number of instruments inoperable at the same time. The Completion Time associated with Condition A is based on the initial entry into Condition A and is not tracked on a per instrument basis. Declaring subsequent instruments inoperable, while Condition A is still in effect, does not trigger the tracking of separate Completion Times.
Once one of the instruments has been restored to OPERABLE status, the Condition A Completion Time is not reset, but continues from the time the first instrument was declared inoperable.
The Completion Time may be extended if the instrument restored to OPERABLE status was the first inoperable instrument.
The Condition A Completion Time may be extended for up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> provided this does not result in any subsequent instrument being inoperable for > 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

The Note above the ACTIONS Table is a method of modifying how the Completion Time is tracked. If this method of modifying how the Completion Time is tracked was applicable only to a specific Condition, the Note would appear in that Condition rather than at the top of the ACTIONS Table. The Note allows Condition A to be entered separately for each inoperable instrument, and Completion Times tracked on a per instrument basis. When an instrument is declared inoperable, Condition A is entered and its Completion Time starts. If subsequent instruments are declared inoperable, Condition A is entered for each instrument and separate Completion Times start and are tracked for each instrument.
If the Completion Time associated with an instrument in Condition A expires, Condition B is entered for that instrument.
If the Completion Times associated with subsequent instruments in Condition A expire, Condition B is entered separately for each instrument and separate Completion Times start and are tracked for each instrument.
If a instrument that caused entry into Condition B is restored to OPERABLE status, Condition B is exited for that instrument.
Since the Note in this example allows multiple Condition entry and tracking of separate Completion Times, Completion Time extensions do not apply. (continued)

1.4 Frequency
PURPOSE DESCRIPTION The purpose of this section is to define the proper use and application of Frequency requirements.
Each ODCM Radiological Effluent Surveillance Requirement (RSR) has a specified Frequency in which the Surveillance must be met in order to meet the associated ODCM REC. An understanding of the correct application of the specified Frequency is necessary for compliance with the RSR. The "specified Frequency" is referred to throughout this section and each of the Requirements of Section 12.0, ODCM Surveillance Requirement (RSR) Applicability. The "specified Frequency" consists of the requirements of the Frequency column of each RSR, as well as certain Notes in the Surveillance column that modify performance requirements.
Sometimes special situations dictate when the requirements of a Surveillance are to be met. They are "otherwise stated" conditions allowed by RSR 12.0.1. They may be stated as clarifying Notes in the Surveillance, as part of the Surveillance, or both. Example 1.4-4 discusses these special situations.
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 REC is within its Applicability, represent potential RSR 12.0.4 conflicts.
To avoid these conflicts, the RSR (i.e., the Surveillance or the Frequency) is stated such that it is only "required" when it can be and should be performed.
With a RSR satisfied, RSR 12.0.4 imposes no restriction.
The use of "met" or "performed" in these instances conveys specified meanings.
A Surveillance is "met" only when the acceptance criteria are satisfied.
Known failure of the requirements of a Surveillance, even without a Surveillance specifically being "performed," constitutes a Surveillance not "met." "Performance" refers only to the requirement to (continued)

1.4 Frequency
DESCRIPTION (continued)
EXAMPLES specifically determine the ability to meet the acceptance criteria.
RSR 12.0.4 restrictions would not apply if both the following conditions are satisfied:
- a. The Surveillance is not required to be performed; and b. The Surveillance is not required to be met or, even if required to be met, is not known to be failed. The following examples illustrate the various ways that Frequencies are specified.
In these examples, the Applicability of the REC (REC not shown) is MODES 1, 2, and 3. EXAMPLE 1.4-1 SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY Perform CHANNEL CHECK 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> Example 1.4-1 contains the type of RSR most often encountered in the ODCM. The Frequency specifies an interval (12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />) during which the associated Surveillance must be performed at least one time. Performance of the Surveillance initiates the subsequent interval.
Although the Frequency is stated as 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, an extension of the time interval to 1.25 times the interval specified in the Frequency is allowed by RSR 12.0.2 for operational flexibility. The measurement of this interval continues at all times, event when the RSR is not required to be met per RSR 12.0.1 (such as when the equipment is inoperable, a variable is outside specified limits, or the unit is outside the Applicability of the REC). If the interval specified by RSR 12.0.2 is exceeded while the unit is in a MODE or other specified condition in the Applicability of the REC, (continued)
Page 1-1.4-2 CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls 1.0 USE AND APPLICATION 1.4 Frequency EXAMPLES EXAMPLE 1.4-1 (continued) and the performance of the Surveillance is not otherwise modified (refer to Examples 1.4-3 and 1.4-4 ), then RSR 12.0.3 becomes applicable.
If the interval as specified by RSR 12.0.2 is exceeded while the unit is not in a MODE or other specified condition in the Applicability of the REC for which performance of the RSR is required, the Surveillance must be performed within the Frequency requirements of RSR 12.0.2 prior to entry into the MODE or other specified condition.
Failure to do so would result in a violation of RSR 12.0.4. EXAMPLE 1.4-2 SURVEILLANCE REQUIREMENTS SURVEILLANCE Verify flow is within limits.

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 />.

1.4 Frequency
EXAMPLES EXAMPLE 1.4-2 (continued)
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 RSR 12.0.2. "Thereafter
indicates future performances must be established per RSR 12.0.2, 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. EXAMPLE 1.4-2 SURVEILLANCE REQUIREMENTS SURVEILLANCE
NOTE-------------
Not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> 25% RTP. Perform channel adjustment.
FREQUENCY 7 days 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 within the "specified Frequency." Therefore, if the Surveillance were not performed within the 7 day interval (plus the extension allowed by RSR 12.0.2), but operation was< 25% RTP, (continued)

1.4 Frequency
EXAMPLES EXAMPLE 1.4-3 (continued) it would not constitute a failure of the RSR or failure to meet the REC. Also, no violation of RSR 12.0.4 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. Once the unit reaches 25% RTP, 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> would be allowed for completing the Surveillance.
If the Surveillance were not performed within this 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> interval, there would then be a failure to perform a Surveillance within the specified Frequency, and the provisions of RSR 12.0.3 would apply. EXAMPLE 1.4-2 SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY
NOTE----------------
Only required to be met in MODE 1. Verify leakage rates are within limits. 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Example 1.4-4 specifies that the requirements of this Surveillance do not have to be met until the unit is in MODE 1. The interval measurement for the Frequency of this Surveillance continues at all times, as described in Example 1.4-1. However, the Note constitutes an "otherwise stated" exception to the Applicability of this Surveillance.
Therefore, if the Surveillance were not performed within the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> interval (plus the extension allowed by RSR 12.0.2), but the unit was not in MODE 1, there would be no failure of the RSR nor failure to meet the REC. Therefore, no violation of RSR 12.0.4 occurs when changing MODES, even with the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Frequency exceeded, provided the MODE change was not made into MODE 1. Prior to entering MODE 1 (assuming again that the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Frequency were not met), RSR 12.0.4 would require satisfying the RSR. Page 1-1.4-5 1.0 USE AND APPLICATION 1.5 REC and RSR Implementation CY-LA-170-301 Revision 7 January 2016 Part I, Radiological Effluent Controls The ODCM provides those limitations upon plant operations which are part of the licensing basis for the station but do not meet the criteria for continued inclusion in the Technical Specifications.
It also provides information which supplements the Technical Specifications by implementing the requirements of Technical Specification Sections 5.5.1, 5.5.4, 5.6.2, and 5.6.3. RECs and RSRs are implemented the same as Technical Specifications (see 12.0 Applicability).
However, RECs and RSRs are treated as plant procedures and are not part of the Technical Specifications.
Therefore the following exceptions apply: a. Violations of the Action or Surveillance requirements in a REC are not reportable as conditions prohibited by, or deviations from, the Technical Specifications per 10 CFR 50.72or10 CFR 50.73. b. Power reduction or plant shutdowns required to comply with the Actions of a REC are not reportable per 10 CFR 50.72or10 CFR 50.73. Page 1-1.5-1

Failure to meet a RSR, whether such failure is experienced during the performance of the RSR or between performances of the RSR, shall be failure to meet the REC. Failure to perform a RSR within the specified Frequency shall be failure to meet the REC except as provided in RSR 12.0.3. RSRs do not have to be performed on inoperable equipment or variables outside specified limits. The specified Frequency for each RSR is met if the RSR is performed within 1.25 times the interval specified in the Frequency, as measured from the previous performance or as measured from the time a specified condition of the Frequency is met. For Frequencies specified as "once," the above interval extension does not apply. If a Completion Time requires periodic performance on a "once per ... " basis, the above Frequency extension applies to each performance after the initial performance.
Exceptions to this RSR are stated in the individual RSRs. If it is discovered that a RSR was not performed within its specified Frequency, then compliance with the requirement to declare the REC not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified Frequency, whichever is greater.

If the RSR is not performed within the delay period, the REC must immediately be declared not met, and the applicable Condition(s) must be entered. When the RSR is performed within the delay period and the RSR is not met, the REC must immediately be declared not met, and the applicable Condition(s) must be entered. (continued)
