Revised Technical Specification Pages (Page 1 of 8)
Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.19 Risk Informed Completion Time Program (continued) e.
A RICT Calculation must include the following hazard groups:
Internal Events PRA (IEPRA) model (includes internal floods)
Internal Events Fire PRA (FPRA) model Seismic PRA (SPRA) model High Winds PRA (HW PRA) model Changes to these means of assessing the hazard groups require prior NRC approval.
f.
The PRA models used to calculate a RICT shall be maintained and upgraded in accordance with the processes endorsed in the regulatory positions of Regulatory Guide 1.200, Revision 3, Acceptability of Probabilistic Risk Assessment Results for Risk-Informed Activities.
g.
A report shall be submitted in accordance with Specification 5.6.11 before a newly developed method is used to calculate a RICT.
CALLAWAY PLANT 5.0-24 Amendment No.
Reporting Requirements 5.6 5.6 Reporting Requirements (continued) 5.6. 1 0 Steam Generator Tube Inspection Report A report shall be submitted within 180 days after the initial entry into MODE 4 following completion of an inspection performed in accordance with Specification 5.5.9, Steam Generator (SG) Program. The report shall include:
a.
The scope of inspections performed on each SG; b.
The nondestructive examination techniques utilized for tubes with increased degradation susceptibility; c.
For each degradation mechanism found; I.
The nondestructive examination techniques utilized; 2.
The location, orientation (if linear), measured size (if available),
and voltage response for each indication. For tube wear at support structures less than 20 percent through-wall, only the total number of indications needs to be reported; 3.
A description of the condition monitoring assessment and results, including the margin to the tube integrity performance criteria and comparison with the margin predicted to exist at the inspection by the previous forward-looking tube integrity assessment; and 4.
The number of tubes plugged during the inspection outage; d.

The number and percentage of tubes plugged to date, and the effective plugging percentage in each steam generator; and f.
The results of any SG secondary side inspections.

Reporting Requirements 5.6 5.6 Reporting Requirements (continued) 5.6.1 1 Risk Informed Completion Time (RICT) Program Upgrade Report A report describing newly developed methods and their implementation must be submitted following a probabilistic risk assessment (PRA) upgrade associated with newly developed methods and prior to the first use of those methods to calculate a RICT. The report shall include:
a.
The PRA models upgraded to include newly developed methods; b.
A description of the acceptability of the newly developed methods consistent with Section 5.2 of PWROG-19027-NP, Revision 2, Newly Developed Method Requirements and Peer Review; c.
Any open findings from the peer review of the implementation of the newly developed methods and how those findings were dispositioned; and d.
All changes to key assumptions related to newly developed methods or their implementation.

High Radiation Area 5.7 5.0 ADMINISTRATIVE CONTROLS 5.7 High Radiation Area As provided in paragraph 20.1601(c) of 10 CFR Part 20, the following controls shall be applied to high radiation areas in place ofthe controls required by paragraph 20.1601 (a) and (b) of 10 CFR Part 20:
5.7. 1 High Radiation Areas with Dose Rates Not Exceeding I.0 rem/hour at 30 Centimeters from the Radiation Source or from any Surface Penetrated by the Radiation:
a.
Each entryway to such an area shall be barricaded and conspicuously posted as a high radiation area. Such barricades may be opened as necessary to permit entry or exit of personnel or equipment; b.
Access to, and activities in, each such area shall be controlled by means of Radiation Work Permit (RWP) or equivalent that includes specification of radiation dose rates in the immediate work area(s) and other appropriate radiation protection equipment and measures.
C.
Individuals qualified in radiation protection procedures and personnel continuously escorted by such individuals may be exempted from the requirement for an RWP or equivalent while performing their assigned duties provided that they are otherwise following plant radiation protection procedures for entry to, exit from, and work in such areas.
d.
Each individual or group entering such an area shall possess:
I A radiation monitoring device that continuously displays radiation dose rates in the area; or 2.
A radiation monitoring device that continuously integrates the radiation dose rates in the area and alarms when the devices dose alarm setpoint is reached, with an appropriate alarm setpoint, or 3.
A radiation monitoring device that continuously transmits does rate and cumulative dose rate information to a remote receiver monitored by radiation protection personnel responsible for controlling personnel radiation exposure within the area, or 4.
A self-reading dosimeter (e.g., pocket ionization chamber or electronic dosimeter) and (continued)

Be under the surveillance as specified in the RWP or equivalent, while in the area, by means of closed circuit television, of personnel qualified in radiation protection procedures, responsible for controlling personnel radiation exposure in the area, and with the means to communicate with individuals in the area who are covered by such surveillance.
e.
Except for individuals qualified in radiation protection procedures, entry into such areas shall be made only after dose rates in the area have been determined and entry personnel are knowledgeable of them.
5.7.2 High Radiation Areas with Dose Rates Greater than I.0 rem/hour at 30 Centimeters from the Radiation Source or from any Surface Penetrated by the Radiation. but less than 500 rads/hour at I Meter from the Radiation Source or from any Surface Penetrated by the Radiation:
