Radioprotection strategy
Shutdown Day 1 :

Buffer zone ready to receive material in SX1

UX15 general RP survey

Collect of some of the material sampling (ID) and
spectroscopy analysis to control the RP calculations
The results of the material samples analysis will determine the need to wear or
not protective equipment (masks, gloves ,..). This is not expected today

Classification of the radioactive waste area with RP (inform all
concerned teams)

Definition of the operational radioactive zone (inform all the
concerned teams)
RPE / RPA interventions
 At each relevant step of the opening scenario and detectors
activities, RPE / RP will intervene to do RP measurements and collect
dust for analysis.
 RPE will be in charged to measure, trace and assist transport of all
material coming from the radioactive waste area.
Note that additional persons from the intervening teams and from
safety team will be trained to perform RP measurement and
traceability for the material coming from the conventional area.
Reminder : all material exiting the radioactive and operational zones
shall not exit the Toroid area, shall be transported via crane to the
radioactive buffer zone on surface, shall be removed and transported
under RPE supervision

RPE / RPA interventions
 The RPE major interventions schedule will be agreed with Michel
for the opening scenarios and the detectors activity responsible.
 The activity responsible will communicate the detailed schedule
at least 1 hour before the beginning of the required intervention
 The detailed opening scenario will be daily updated by Michel
and accessible through the ATLAS web pages
RPE / RPA interventions
RPE shifts proposal
From 6.12 to 29.12: shifts of 2 days including weeks end and
holidays.
From 29.12 to end of the shutdown: shifts of 5 days including week
end and holidays
6
Safety team assistance
 The presence of safety team in situ to assist the intervening teams and
control safety conditions is mandatory.
 We need presence during the major interventions and at least few hour
per days.
 During the Xmas shutdown, some specific safety and infrastructure
systematic checks could be added.
Safety team shifts proposal:
During all shutdown: 2 days shifts including week ends and hollidays.
Concerned persons : Safety team, ADO engineers, TSOs, Safety officers.
Specific training and instructions will be provided.
7
SLIMOS
During all shutdown period :
2 SLIMOS shifts per day (nights covered by OPM)
Beginning of shift at least ½ hour before the Access team shifts
End of shift at least ½ hour after the Access team shifts
