Ralf Trant26/01/2010, 17:00Following the accident in sector 3-4 of 19th September 2008, the related safety of personnel in the LHC underground areas was investigated and preventive and corrective measures recommended. All efforts have been deployed to fulfill the short term recommendations of the Task Force. Still, many of the solutions implemented are of temporary nature and valid only for the 1st LHC physics run in...Go to contribution page

Sylvain Weisz26/01/2010, 17:15The presentation reviews the status of the separation of underground areas from the LHC tunnel and the present pressure release paths in case of a large He leak. We also discuss the shortfalls of the present situation and present the strategy for the upgrade/consolidation of the He release in case of a MCI.Go to contribution page

Olga Beltramello26/01/2010, 17:30The LHC experiments have reached very high levels in Safety to face all possible risks associated to the LHC Run Period. Following appropriate risks assessments, the required level 3 alarm safety systems have been implemented, the radioprotection strategy has been set up, the adequate general and specific safety trainings have been developed. The Experiments safety organization and structures...Go to contribution page

Christoph Schaefer26/01/2010, 17:55The LHC experiments started successfully and safely in November 2009 together with the LHC machine. Significant improvements to the safety of the underground experimental areas have been implemented after the accident of the 19.09.08. Nevertheless, some safety improvements could not have been finalized and therefore compensatory measures are put in place for the 2009/10 LHC run. This...Go to contribution page

John Pedersen26/01/2010, 18:15Following the restructuration beginning of 2009 the EN department took over the territorial safety responsibility for the machines. However, the beam related safety is still handled by BE and the supervision of the LHC safety will switch from the beams department to the EN department during shut downs. This presentation gives an overview of the safety organisation that will be in place during...Go to contribution page

John Etheridge26/01/2010, 18:40The objective of this year’s presentation is to analyze the progress we have all made over the last 12 months, looking at the safety procedures (AOC ,VIC, ADI) define our strong points and see how we can improve them. Identify the weak points and high light the problems. Build in safety from the conception stage of “ALL” project including the LHC, defining the rule and regulation ensure they...Go to contribution page

Doris Forkel-Wirth26/01/2010, 19:00Estimations of losses around the LHC ring for several energy and intensity scenarios for the 2009/2010 run are reviewed. The presentation describes the impact of RP consideration on consolidation work during the next long shut down on potentially highly irradiated items such as experimental beam pipes, TAS and TAN, low-b triplets, collimators and Roman Pots. Access...Go to contribution page

Mauro Nonis26/01/2010, 19:30This presentation reviews the requirements of the HVAC system concerning confinement, filtering and smoke extraction. Being able to release He following minor leaks adds another level of complexity beyond the normal functionalities of a ventilation system. Propositions for upgrades are discussed, with improved sectorisation to fulfill the RP requirements as intensity and energy increase, and...Go to contribution page
