- Description
- Clarifications - Round 2: The following is the second set of clarifications requested from interested parties. Please take this information into account when preparing your quotation. Question 1: Section 3.01 specifies an enclosure comparable to NEMA 12. This question references the sealing. One of the potential offerors makes an enclosure to house the 6030 Ion Chamber, consisting of panels that are screwed to a flange on the body of the enclosure. BSA Response to Question 1 : Yes, a tight metal-on-metal seal meets the enclosure requirements. Question 2: Section 3.04 specifies that the enclosure be physically secure. We would also like to secure the front of the display with a hasp for a padlock. Would an enclosure with screws be considered physically secure? BSA Response to Question 2: Panels affixed to the enclosure body with screws are acceptable. Hinged access points that are secured with hasp and padlock are acceptable. Question 3: Section 7.0.3. Input/Output connectors must be approved by BSA. Do the AMP type CPC circular connectors meet this requirement? The CPC connectors are MS type plastic crimp connectors with gold push in crimp terminals. BSA Response to Question 3: Yes - Such connectors are acceptable. Question 4: Section 8.0 - Nameplate. Does a nameplate need to be on both the detector box and the display box? Would a vinyl label with permanent adhesive meet this requirement? BSA Response to Question 4: Yes - the nameplate should be affixed to both detector and display/processing unit. A vinyl label with permanent adhesive is acceptable. Question 5: Does the equipment to be purchased need to be commercial or nuclear safety grade? BSA Response to Question 5: Equipment does not need to be nuclear safety grade. Question 6: Can BSA provide a block diagram of the system with distances of each detector from its ratemeter? Also, a complete diagram of the positioning of all detectors and ratemeters (with distances) would be preferred to determine the configuration of the system. BSA Response to Question 6: We plan for the detector to be within a 5-meter distance of the display/processing unit. The detector and display units will be wall mounted on accelerator or beam line enclosures located in the Injection or Ring Building. Each unit is expected to provide local alarm of elevated radiation levels and will be connected to the NSLS-II control system to provide interlock function and remote annunciation of alarm in the NSLS-II control room. We do not have diagrams available at this time. Question 7: Can multiple detectors be connected to a single ratemeter if the ratemeter can display all detector exposure rates? BSA Response to Question 7: No. We expect that the separation between detectors will be too great to be able to utilize a single display unit with multiple detectors. The display unit will need to be close to the detector in order to provide local warnings in the affected area. Except as hereby clarified, all other terms and conditions remain the same. Bid due date remains 3/24/2011. Kindly acknowledge receipt of these clarifications.
