The following items are requested for the
Occupational Radiation Safety Inspection
at Wolf Creek
Dates of Inspection: 04/05/2021 to 04/09/2021
Integrated Report 2021002
Inspection areas are listed in the attachments below.
Please provide the requested information on or before Friday, March 19, 2021.
Please submit this information using the same lettering system as below. For example, all
contacts and phone numbers for Inspection Procedure 71124.01 should be in a file/folder titled
1-A, applicable organization charts in file/folder 1-B, etc.
The information should be provided in electronic format or a secure document management
service. If information is placed on a secured document management system, please ensure
the inspection exit date entered is at least 30 days later than the onsite inspection dates, so the
inspectors will have access to the information while writing the report.
In addition to the corrective action document lists provided for each inspection procedure listed
below, please provide updated lists of corrective action documents at the entrance meeting.
The dates for these lists should range from the end dates of the original lists to the day of the
entrance meeting.
If more than one inspection procedure is to be conducted and the information requests appear
to be redundant, there is no need to provide duplicate copies. Enter a note explaining in which
file the information can be found.
If you have any questions or comments, please contact Natasha Greene at 817-200-1154 or via

NOTE: These lists should include a description of the condition that provides sufficient
detail that the inspectors can ascertain the regulatory impact, the significance
level assigned to the condition, the status of the action (e.g., open, working,
closed, etc.) and the search criteria used. Please provide in document formats

efficiently determine appropriate sampling and perform word searches, as
needed. (Excel spreadsheets are the preferred format.) If codes are used,
please provide a legend for each column where a code is used.
H.
List of radiologically significant work activities scheduled to be conducted during the
