Why?

• Goal: Ultimate (CCLRC defined)Safety & Design Review

– How do we get there?• We need a Process

– What is needed?• Full Safety & Design assessment

– How do we ensure success?• Assessment within MICE but outside of the working groups

• Propose Design & Safety Working Group– Based on group involved in AFCSWG¹– Expanded to cover all MICE – in a timely manner

¹ but with fewer letters – easier to repeat!

AFCSWG – as was

• Original Concept for Absorber and Hydrogen System

• Process* heavy for most of MICE

• Ultimate goal stands

Morph to D&SWG…

• Role of existing working groups unchanged• Character and role of the “review panel” is

different:– Internal “audit” process

• unless D&SWG advises that an independent review is needed (matter of risk & competence within MICE)

– D&SWG guides documentation preparation through a series of audits

– D&SWG to assess the documentation• Not the same as a review (less overhead)

– Informs TB & EB on readiness for final review

Phase 1 Time Scales

• Beam Line needs to be in place end of 2006– Complete beam line review by end 2005– Radiation shielding is a more delicate matter– Target is a potential risk to ISIS operations– Beam Line is (probably low risk)

• ISIS/EID engineering staff• Following established & proven practices

• Spectrometer & Tracker– Low risk

• R&D activities– Medium - Potentially High – design to achieve Low Risk
