Preparation for Conducting Decommissioning Actions.

Engaging a Contractor

Gary SimmsANSTO Major Projects Delivery Office

IntroductionGary Simms.• Supervised the Characterisation process.• B22 Dilapidation report• Managed the Containment process from Concept

Design through to the tent installation and commission and handover

• Managed the Fit out of the containment tent.• Engaged the Demo consultant and partook in the

Demo development process with Greg Berry and the project team.

• Prepared the Tender Specification.• Prepared the Emergency plan.• Prepared the Training plan for the induction of the

Demo contractors.• Member of the Tender evaluation committee.• Prepared daily Safety check lists in consultation with

safety Management.• Trained the Ansto Supervisory staff.• Managed the development of the Ventilation Strategy

with our Senior HVAC Engineer and Active Ventilation Safety Approvals Officer.

Procurement process

• Procurement process– You must have a robust scope of work to feed in

to the tender process. Use a consultant who has specialist experience with concrete demolition projects, to provide direct professional advice.

– Tender evaluation process must be tailored to suit the preferred outcome.

Who to Look for

• The Project team could not find a company in Australia (or this hemisphere) with radioactive demolition experience.

Who to Look for

• The closest comparable task to radioactive Bio shield demolition…. is demolition of concrete structures which have a heavy presence of asbestos.

• “Weight” your contractor evaluation and selection process to include all the attributes of a heavy demolition company with asbestos experience and you are 90% there.

Why look to the Asbestos industry

• PPE is the same– P3 full face mask.– Tyvek (paper) Overalls– Wet work

• Disposal tactics are similar. (With regard to wrapping)

• Active contamination and asbestos contamination require similar risk mitigation.

The other 10%

• Turning asbestos removal workers is based on the premise,

– that “our asbestos” (activated Concrete) is easier to detect due to the simple fact that it emits energy…… via instrumentation, you can see and hear radiation and contamination, you can set control parameters that have been proven to be safe within which you can work……this advantage sadly missing in the asbestos removal business.

Sound training from the basics

• The adage that “knowledge dispels fear” is the key to bringing non radiation industry personnel in to the nuclear sector.

• Provide training that is board based and be prepared to answer any questions directly.

• Respect the decisions of those personnel that have decided that this work falls outside of their own personal risk profile.

Encourage Third Party Advice

• Back up this approach with sound 1st principles knowledge.

• Encourage your new radiation workers to seek third party advise from professionals, IAEA web site is a good place to start (not your mates), and encourage them make independent informed decisions as to the safety risks of working on a reactor demolition Project.

The assessment process

– Government Procurement Guideline.• Rigid, strict, but fair and auditable.

– Ansto Evaluation plan (which meets the GPG) has the flexibility to “weight” selection criteria.

• The experience criteria in the plan was 15% of the total success criteria, more than enough to tip the balance toward the best skilled rather than the best price.

Evaluation Criteria

Be transparent with risk

• Total disclosure of risk, and mitigation of that risk.

• Do not be tempted to pay a “safety bonus” -from past experience they encourage concealment of injury….and by default the potential for the concealment of contamination….. Avoid at all cost!

Keep the Contractor Happy!• Take the pressure off the contractor.

– Ansto owned environmental risk (monitoring, containment, ventilation, and

disposal) this allowed the contractor to concentrate on his own expertise. Note! if you contract these core business skills out you run the risk of losing control….This “Turn key” contract approach was rejected by the project team for these reasons.

– Do not have milestones that can not be moved.– Be prepared to have a large contingency and be prepared to use it.– Do not penalise the contractor for delays beyond his control, i.e.

environmental control, contamination control, regulatory control delays.

– Have a daily site log that is open to both the contractor and the Client and Regulator……Record issues, as and when they occur, and sign them off day by day(prevents augments, and stops the “creative” memory process).

Attributes of a good Active Demo Contactor

• Expertise of the contractor.– Proven safety management experience.

• Ask to see samples of non conformance reports in the safety plan.

– Demolition expertise– Asbestos experience.– Good past references (Do background checks

and get references).

The Big 5Be prepared for the big 5 questions from your new contractors. •The following, in order of frequency with translations, were the big 5 for the Moata Project during the tender and training process.

– Can I still have children?• = What are the biological effects of radiation?

– Will I glow in the dark?• = Opportunity to explain why it does happen …..but not to you!

– What happens if I become contaminated?• =Can you explain prevention?

– What happens if my Demo Equipment becomes contaminated?• = what are your decontamination procedures?

– Has anybody been hurt with radiation?• = How good is your safety record?

Risk recognised from the beginningExcerpt from the Tender Evaluation Report as written by Project Manager Alec Kimber to the steering committee before award of the contract to Cardinal

Key statement to Arpansa

Training Plan

• Top Tips– Make sure questions from contractors are

answered by the correct expert, do not be tempted to guess, if you are not sure…. defer.

– Concerns from your contractor are Gold…value them as if your project depended on it, because it does….Note, its ok to change and amend SWMES (Safe Work Methods & Environmental Statement) as you GO.

Lessons learnt• Good Contractor Selection is crucial (Asbestos Demo is a good

place to start).• Own environmental risk control.• Good contractor training can allow you to use non-radiation

industry personnel for active demo work.• Use an independent Demolition Consultant (Greg Berry) to help

develop and review the scope of work document.• Take the Pressure off the contractor.• Constant supervision and consultation is a must.• Large temporary containment system can work well.• Ansto has the in-house know how to provide safe environment for

active decontamination demolition.
