Scope of work: Safe Storage Minimum Complement Changes

Estimated Contact Length: 6 - 12 months

Department: Nuclear Training

Task Summary: Training Analysis, Training Development and other training tasks

Location: Remote, you will be provided the necessary documentation, to complete this scope of work. Based on current Covid restrictions, work will be carried out virtually to the extent possible

Position Summary:

OPG is currently in the process of planning for the permanent shutdown of the Pickering Nuclear Generating Station. The current plan is for Pickering units 1 and 4 followed by units 5 - 8 to end commercial operations at the end of 2024 and 2025 respectively. As units enter their permanent guaranteed shutdown state, they will enter a safe storage period during which systems no longer required will be end stated and others modified as required to support a long term Storage with Surveillance (SWS) phase. The SWS period is nominally 30 years after which time the station will be dismantled.

Once the units are shut down, the units will be defueled, transferring their inventory to the irradiated fuel bays (IFBs). Also, D2O will be removed from the unit reactor buildings and placed into long term storage in various tanks. Once these transfers have occurred for each unit, the risk profile of each unit changes significantly. The focus of nuclear safety analysis will transition to the IFBs, and the potential for loss of bay cooling or inventory accidents. As a result, minimum compliment and emergency response requirements can also be adjusted inline with the reduced risk profile. This will support a reduction in minimum staffing in order to align with the future of the Pickering Site. The purpose of this scope of work is to identify the required changes to PNGS training and minimum complement staffing post defuel and dewatering of each of the reactor units.

Task Description:

Task 1: Revision of the Task Analysis for Authorized staff and other minimum shift complement positions. Revisions will be based on the elimination of Unit Based design basis accidents. The only remaining DBAs will be centred on the IFBs and D2O storage. TCD: Q2 2022.

Task 2: Update task to Training Matrices. For Authorized positions and other minimum complement positions, the task to training matrices will need to be revised to reflect the required tasks identified in the updated task analysis. TCD: Q2 2022

Task 3 Identify the station minimum complement staffing requirements based on the previous tasks. TCD: Q2 2022

Task 4: Update Minimum Complement Training Requirements. Training courses will need to be updated to include training for Pickering in the Safe Storage/Storage with Surveillance states, and the elimination of course/requirements for unit based DBAs. TCD: Q2 2022. Note: Consideration should be given to initial vs continuing training. Continuing training will be required for tasks that hit a certain threshold on a DIF rating.

Task 5 Procedure Updates. Operations, maintenance, and other response procedures will need to be updated based on the tasks above. TCD: Q2 2022

Special Requirements/Quality Considerations/Interactions/Communication

It is expected that the contractor will be available to conduct a kick-off meeting and commence work within 1 week of award of the contract. The contractor will provide a preliminary schedule of activities with their proposal for acceptance by OPG. The schedule should demonstrate completion of tasks 1-4 and the list of procedures to be updated for task 5 by end of Q2 2022.

Contractor effort and schedule of activities may be adjusted based on consultation and approval by OPG to support timely completion of this scope of work.

Deliverables

• Updated Task Analysis and Task to Training Matrices for post defuel/dewater minimum compliment positions by unit if applicable.
• Updated Task to Training Matrices for post defuel / dewater minimum complement positions.
• A list of Minimum Shift Complement positions in the post defuel / dewater state by unit if applicable
• A list of required training and a proposal for preparation of updated training material for those courses.
• A list of procedures to be updated, and TPARs with the required update information.
• The contractor should assume one round of revision for each deliverable before finalization. OPG will commit to providing consolidated comments within two weeks of receipt of deliverables to facilitate this process.

Qualification Requirements
