Radiation Monitors (?) Rules: Keep radiation level < 1mSv over one year (2000 h), 0.5 µSv/h Purchasing of Radiation Monitors in progress (expected June 2013): - 5 movable combined stations connected to PSS through interlock signals. - 2 portable Gamma. 2 portable Neutrons. 2 Gamma spectrometers and calibrations kits outside tender/later. Passive: - Gamma dosimeters/ SESAME. - Neutron TLD’s outsourcing (JAEC).
Plan and time schedule for PSS • - The Personal Safety System of SESAME must comply with norm IEC 61508 (SIL-3) • All SIL-3 equipments must be approved from Jordan Institution for Standards and Metrology (JISM) Organization??? • The contractor will be responsible for providing all the hardware and software of PSS. • Tasks will be Shared between contractor and SESAME as follows: • Contractor tasks: • 1. Programming the PSS PLCs by a certified PLC programmer. • 2. Assembling and installing the PSS cabinets (Booster tunnel & Control room PSS cabinets) • 3. Training SESAME staff for safety PLC programming. • 4. SAT in cooperation with SESAME staff. • 5. Providing the drivers needed to connect PSS PLCs to monitoring system of PSS. • 6. Providing the documentation.
Plan and time schedule for PSS b) SESAME tasks: Installing the PSS field hardware and connecting the interlock signals to the cabinets terminals. (an electrical technician should be hired) All field cabling and installing cable trays. SAT in cooperation with contractor. Monitoring system for PSS by EPICS (control team + PSS engineer) Preparing the final documentation of PSS.
