TMI- 1 Standing Order Rev. 3- Issued 12/2/09@ 0'1:05ý This order applies any time the Containment Liner Plate is breached and is applicable to all station personnel, including but not limited to Operations, Maintenance., SGT, Shaw, Rad Pro and Chemistry Operations will maintain RB Purge Exhaust flow in order to maximize air inflow thru the RB Openings (both the Equipment Hatch and the RB construction opening)
If at any time airflow is observed by any personnel to be out of the RB openings, notify the Operations Control Room Supervisor (x8071).
The Radiation Protection GRCS will ensure documented observation of air inflow/tarp inward deflection at a minimum of once every 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> by observing ribbon strips or tarp deflection at the RB openings (see attached table). In addition, once per day I&C will take airflow measurements at the construction opening and the equipment hatch.
All personnel will obtain permission from the Operations Control Room Supervisor (x8071) prior to changing the configuration of RB openings. Personnel may pass through the tarps without contacting Operations. They shall ensure the tarps are fully closed after each passage.
Prior to granting permission to manipulate RB openings, The Operations Control Room Supervisor will evaluate the following:
___ Stable Purge exhaust Stable Aux and FHB exhaust flow
___ Discuss with the duty RPM or the OCC RPM any radiological evolutions in progress or planned and ensure adequate controls are established to allow opening of containment
___ The duty RPM or the OCC RPM will verify stable RB airborne activity
___ Airborne activity monitors near RB openings are operating
___ An RB opening closure plan is established that includes at a minimum, the supervisor responsible to close the opening, contact phone # and radio channel, and estimated time to close the opening A continuous airborne radioactivity monitor capable of alarming shall be operating near the RB openings. This requirement can be waived by duty RPM provided the requirements of RAF 09-011 are met.
The Radiation Protection GRCS will ensure recording of airborne radiation monitor indications near the RB openings at a minimum of once every 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (see attached table)
If airflow exists out of an RB opening or if an airborne Radiation Monitor at an RB opening rises to > 0.3 DAC, then perform the following:
Discontinue work activities with potential to cause airborne contamination in the RB until evaluated by ttieduity RPM or the OCC RPM to ensure propr egineering controls are in place, and approved by the Shift Outage Manager
___ Evaluate radiation release impact
___ Close the opening with outflow or if closure is not possible, document the time, airflow measurement/estimate, and duration of outward flow for evaluation of non-routine release Evaluate EAL's Generate IR
