Summary of Presentations

Paraphrased Quick walk down memory lane

3

Opportunities for improvement in the accelerator safety documentation

· Recommended better consistency and control of documentation

Good findings

· Tracking training for personnel

· Safety culture

· FSO Oversight Program

Fermi Lab Assessment – Scott Davis

ASO Revision Process – Scott Davis

Develop a minimum set of requirements Discuss approaches at Accelerator Safety Workshop Provide changes to the accelerator community as soon as practical Request comments from the accelerator community Prepare Justification Memorandum by September 30, 2009

5

The End State – Scott Davis

Performance based contracts with the right “requirements set” External regulation of safety Fully developed contractor assurance systems DOE Contract Management replaced by DOE Performance Management 2 to 3 year time frame

6

NSLS Experiment ESH Review – Andrew Ackerman

Formal documented process Electronic submissions by user NSLS liaisons assigned and ESH reviewed with user Authorizations required to start Beam line safety checklist developed Training of users checked

· Efficient web based training· Hands on training at beam-line· Training records maintained

Experiment begins

7

User Training APS – Steve Butala

APS core courses available remotely via web Training determined by experiment safety analysis or Training determined by job hazard questionnaire Lecture and practical training for several hazards Training verified Training records maintained Experiment is authorized by signatures; posted at beam line

8

Large Experiment Collaboration Structure and Training at FNAL – Don Cossairt

Large user collaborations (100s to 1000s) Experiments are institutions (procedures, policies) Formal MOUs including ESH section with FNAL ESH policies are same for FNAL employees and FNAL users Individual training needs assessments performed Web based, lecture and hands on training are in use Centralized ESH training where practicable Records maintained Language is a challenge Keeping user training current is a challenge

9

851 Exposure Assessment – Jim Floyd

Three tiered system proposed at LBNL· Hazard identification using risk based screening· Qualitative assessment and professional judgment· Quantitative assessment determined by decision tool

10

IH Monitoring Issues at Accelerators – Jim Floyd

Nano – need technical basis for sampling Nano – need standards for measurement interpretation Nuisance noise – when do you mitigate? Lasers – portability of third party eye exams ODH issues in labs – probability of event is low

11

DOE Accelerator Software and QA – Matt Cole

Pick a standard or combination of standards Map to the 10 DOE QA criteria Address the integration of software with hardware and humans Establish effective configuration management Periodically assess Share experiences

12

Draft DOE Standard Application Of Safety Instrumented Systems Used At DOE Non-reactor Nuclear Facilities – Asher Etkin

There is a lot of useful material in this standard For the accelerator community to benefit, we must extract

useful material into a separate guidance document

13

Metals Suspension, Moratorium – Sayed Rokni, George Goode

Accelerator community and Office of Science must engage in the process to lift the moratorium and develop workable solutions to this problem

SC and/or contractor staff should participate in the Los Alamos visit as observers and share lessons learned

Accelerator community should form a working group to develop a consensus position regarding lifting the moratorium and for review/comment in REVCOM of the revised DOE O 5400.5 

14

Update on Metals Recycling at DOE Facilities – Don Gregory

Use alternative approaches· Re-use· Common sense agreements with DOE· Retroactive de-posting

Issue has the attention of the Secretary of Energy

15

SNS Modulator Fires – David Anderson

Many “smoke generating” events to date Nature of component failures well understood PM and component replacement underway

16

BNL S-band LINAC Fire Safety Concerns – Andrew Ackerman

Three similar fires, 1999, 2003, 2009 – 3 BNL acceleratorsUnderstood the systems and the risks they present Identified controls (fire or arc detection, procedures, disconnects)Larger open issues:

• Sharing information and resources at BNL• Implementing complete and consistent corrective actions• Establishing standards for equipment design and maintenance

17

NFPA 101-2009 – E. Michael Saleski

Typical accelerator enclosure hardware does not meet standard Time delay release with audible alarm may be an acceptable solution

18

Contractors' Internal Self-Assessment Programs that Meet ASO Requirements

BNL, ANL, ORNL, FNAL, TJNAF, SLAC, LBNL meet ASO requirements

Approaches vary

19

Human Performance Initiatives, ORNL and BNL - Sam McKenzie and Ray Karol

Human performance initiatives take several years to implement Consultants and motivated employees should be involved in startup Culpability schemes are useful Error reduction in all business areas can be experienced, not just safety HPI tools and training are maturing

20

Panel Sessions

What is the Appropriate Role of the Accelerator Safety Order?· Views of contractors and DOE were expressed· Contractors support the Order

Recent Accelerator Events and Lessons Learned· Modifications to RHIC after the CERN Event, J. Tuozzolo

- Latent hazardous conditions at RHIC were discussed· Radioactivity release at Holifield, B. A. Tatum

- Improvements to maintenance program, radiological surveillance program, SAD and emergency response were discussed
