RP-AA-461 Revision 2 Page 20 of 23 ATTACHMENT 3 Pre-Dive Checklist Page 1 of 1 (USED FOR SUBSEQUENT DIVES AFTER CREW'S INITIAL BRIEF. MAY BE PERFORMED IN ANY ORDER)

Ai PEDIVEiCH ECK i,-!CIiPt.eoe ie Inft7N/A,

1. Complete a pre-job briefing (discussion to include dive area boundaries, dose rate information and task(s)).
2. Verify two underwater survey instruments are in calibration and source checked and are available.
3.

Verify water clarity and underwater lighting adequate.

4.

Verify dive site survey is performed (historical survey available for initial dive) and methodology by RP Supervision approved.

5.

Verify dive suit is wet prior to diving.

6.

Verify diver's suit(s) is surveyed and meets the requirements of step 4.3.5

7.

Verify helmet dosimetry attached with wire/plastic ties, when applicable. Do not use material, such as plastic bags or tape, which could block diver's exhalation valve.

8. Verify diver dosimetry in proper location (e.g., EDs, TLDs, Extremity, etc.).
9.

Verify remote dosimetry equipment is operational.

t.

10. Verify two-way voice communications are available and operational.
11. Verify approved method of visual contact is available.
12. Verify survey instrumentation used by diver is operable.
13. Verify in-leakage test of diver suit has been performed.
14. Verify that breathing air is monitored.
15. Evaluate the need for vacuuming and shielding.
16. Ensure all prerequisites of RP-AA-461 are met prior to dive operations.
17. Discuss immediate actions for each the following: CO alarm, High Rad alarm, CAM alarm, diver disorientation, diver signaled to leave, failure of underwater survey instrumentation, diver reaches pre-established dose limits, radiological aspects of dive can NOT be maintained or are suspect
18. Discuss when the dive operations shall be suspended as per step 4.4.7.
19. Verify with Diver Supervisor that Ops Shift Supervision has been notified prior to start of dive evolutions.
20. Ensure appropriate controls are in place for dive evolutions in a high dose rate gradient area.
21. Ensure water are within limits. (<95= F unless approved by Dive supervisor aned pree to notiftiLon to RPISafety)
22. Discuss approved dose levels with divers.
23. When meeting the requirements of step 3.3.11, ensure a documented plan exists with the appropriate approvals when evaluating diver safety.

If Discrete Radioactive Particle >10 mrad/hr and 4500 mrad/hr, then RPT to survey diver suit approximately every 1/2 hr, perform detailed survey, cilect paruices and allow diver to return to water.

If Discrete Radioactive Partice >500 mrad/hr, then immediately remove diver from suit. perform detailed survey of suit, characterize prtidtes and Initiate dose assessment.

(g r Briefin, Content: (checkiinitial completed steps)

Introduce brief with statement identifyifig briers purpose. (Example: 'This is a High Radiation Area or Locked High Radiation Area Brief.')

SInform worker they are responsible for ensuring correct RWP is being used.

A Use survey or location maps as appropriate to accurately identify location of work activities / entries.

,4 Identify dose rate in work area.

e Identify low dose area information.

~

Identify required dosimetry.

Identify alarm set points.

0016V 0 Identify maximum stay-times.

SInform worker to conduct self-check of ED alarm set points against set points noted on Radiation Worker Pocket RWP Data Sheet prior to HRAsLHRA entry.

Inform worker that a verification of ED alarms set points should be conducted if entering HRAILHRA with another individual.

Inform worker to verify ED has a display prior to HRA /LHRA entry (Reinforce need to check dose frequency while in HRA/LHRA).

Inform worker to NOT move material within area that will increase boundary dose rates without RPT in attendance.

4 Discuss proper control of barricades and postings upon entering I exiting area StInform workers that if they identify an uncontrolled unlocked access point that they must control the area and contact
