| (RFP, Attachment #, etc.) | Page Number and Paragraph Header from Source | Question | Answer | ||
| 1 | RFP Section C | ||||
| Attachment 1 | Pg 92 Survey | Is there any information available that can be used to estimate the radionuclides present/likely to be present within the line sections subject to removal to use for ALARA planning and WAC compliance purposes? | Likely Cobalt-60, Cesium-137, Ce-144/Pr144, Tritium | ||
| 2 | RFP Section C, | ||||
| Attachment 1 | Pg 11, Para 2.13 NIST HP support and Oversight; pg 83 support including PPE. | Will NIST provide temporary radiation shielding, contamination control materials, and negative pressure HEPA systems as part of Health Physics Support? | NIST does have ~500 lead bricks and about a dozen lead sheets (4'x4'x.25"), but contractors should plan to bring shielding. | ||
| 3 | RFP Section C, | ||||
| Attachment 1 | Pg 92 Survey | There is significant temporary shielding around the base of the line section along with lead bricks banded to the pipe. For ALARA planning purposes, what are the unshielded contact/30 cm dose rates in these areas? | Unshielded dose rates are not known. | ||
| 4 | RFP Section C | ||||
| Pg 9, Para 2.4 General Requirements | Does the facility have administrative control limits for internal/external dose established at levels below 10 CFR 20 limits? | 100mrem/week that can be exceeded based on management approval | |||
| 5 | RFP Section C, | ||||
| Attachment 1 | Pg 92 Survey | For system breaches on this nature, what are the typical levels of PPE and respiratory protection used by NIST? | NIST does not have an NRC approved respiratory protection program. In almost all cases external dose rates greatly exceed potential for uptake doses. Our preference is to use engineered ventilation controls. | ||
| 6 | RFP Section C | Pg 79, Para 4.2 Fuel Transfer Valves, and Pneumatic Actuators | We are currently experiencing difficulty getting quotations from vendors to supply the specific valves and actuators identified in the RFP. For the purposes of pricing the Mock Task Order, can we take exception to pricing these components at this time, and after contract award, we will work with NIST on sourcing with cost, schedule and lead times? | No, price is part of the evaluation. NIST requires a best estimate and how you came up with it if legitimate quotes are not able to be provided. | |
| 7 | RFP Section C | Pg 79, Para 4.2 Fuel Transfer Valves, and Pneumatic Actuators | Would NIST consider sourcing the valves and actuators themselves, and providing to the contractor, as Govt Furnished Equipment? | No, NIST will not consider sourcing the valves and actuators. | |

| 26 | RFP Section C | Attach 1 | What time frame will be required to notify client of expected overtime to support completion of work in progress | Scheduling will be handled on a task order basis. It will be discussed prior to award of individual tasks | |
| 27 | RFP Section C | Attach 1 | Please provide information on the badging process and expected duration. Background checks, inprocess training and General Employee Training (GET), including Level 1 and Level 2 and respirator training. | Badging varies based on an individual's expected length of time on site. This will be handled on a task order basis after award. In general, individuals expected to be onsite for 10 days or fewer in a calendar year will expect 2-3 days processing and require 100% escort. Individuals expecing to be onsite for 6 months or fewer will receive a limited access badge. Individuals expected to be onsite for more than 6 months will go through a 2-3 month process including fingerprinting and vetting. For unescorted access in the NCNR, a separate badge is required. Proof of Radiation Training per 10 CFR 19 and onsite training/briefing is required. This will be discussed more after award. There is no respirator training. | |
| 28 | RFP Section C | Attach 1 | What areas will be available for fabrication needs on site during project execution? | This will be determined on a task order basis as it is dependent on the work. Space is available for welding and minor fabrication. | |
| 29 | RFP Section C | Attach 1 | What areas will be available for tooling and equipment storage? | This will be addressed with the contract awardee, prior to award of individual task orders. | |
| 30 | RFP Section C | Attach 1 | Please provide requirements for "like for like" equipment replacement in the event the specific equipment ( valves, operators) are obsolete, or unavailable. | A like-for-like replacement is defined as the replacement of an item with an item that is identical. For example, the replacement item would be identical if it was purchased at the same time from the same vendor as the item it is replacing, or if the user can verify that there have been no changes in the design, materials, or manufacturing process since procurement of the item being replaced. If differences from the original item are identified in the replacement item, then the item is not identical, but similar to the item being replaced, and an evaluation is necessary to determine if any changes in design, material, or the manufacturing process could impact the functional characteristics and ultimately the component's ability to perform its required safety function. | |
| 31 | RFP Section C | Attach 1 | During walkdown on 2-19-25 there were some P&ID and PFD drawings taped to hallway wall near access to RFP sow piping. Please provide copies of those drawings in the RFP. | See Attachments to this Amendment. | |
| 32 | RFP Section C | Attach 1 | The door way to the work area has 2 I-beam cross members at top of access. Can NIST supply the lifting rating on same I-beams? | These should be standard I-beams, but directive is not to use these for lifting. | |
| 33 | RFP Section C | Attach 1 | There are lifting eyes in work area above piping. Are these lifting eyes rated with calculations? Will there be a load testing requirement by NIST prior to use, and will NIST perform that load testing? | Contractor is prohibited from using the ceiling lifting eyes. | |
| 34 | RFP Section C | Attach 1 | Are the rigging eyes in the ceiling of room outside the reactor opening suitable for use in project execution? | Contractor is prohibited from using the ceiling lifting eyes. | |
| 35 | Amendment 4 | Page 1, L.5 | Given the extent of questions asked and the timeframe to accomodate NIST answers into our proposal, we are requesting consideration of a proposal due date extension day-for-day for any answers received after Thursday/2-27. | NIST has extended the proposal due date to no later than 5pm, Friday, March 14, 2025. | |
| 36 | General | General | If the vendor could supply a bare stem valve so that it would mate up with the existing actuators, would that be a desirable option (this has been done for other plants)? | The intent is to have new actuators installed. | |
| 37 | General | General | For the actuators, are there accessories that the vendor would also need to provide (solenoids, regulators, switches, tubing) or would that be outside of the scope? | Refer to section 3.2.2 of the SOW. | |
| 38 | General | General | The Mock Task Order CLIN is 00010 which is the same as the Project Manager rate for the first twelve months. To avoid confusion, can this be changed to 00050? | No, the IDIQ contract and any resulting task order would be two separate contracts so this should not cause confusion once awarded. | |
| 39 | General | General | The following questions are requested for clarifications of the mock task: | ||
| 40 | Where is the piping stack-up supported? See figure to the right for additional detail. | FTV3 and the Pool Transition Dropout Chute are supported by the cover plate. The pipe section is through-bolted to the FTV. Photos included. | |||
| 41 | What is the width of the access door? | The door to process room is 42" x 78". Door to subpile room is 36" x 66". | |||
| 42 | Is the flange above FTV-1 a raised face? | Contractors should assume raised face for the mock task order | |||
| 43 | What does section 4.7.4 recheck mean? Is it only for the expansion joint? | For purposes of the mock task this is only for the expansion joint. | |||
| 44 | What is the survey report referenced as task #4 on page 81 refer to? Metrology? Will the scaffold get removed to support? | The ask is for the Contractor to perform a site visit ahead of disassembly to verify as-built conditions and dimensions | |||
| 45 | What does NDT, Leak & pressure Test of Assembly referenced as task #4 on page 81 refer to? For post installation welding? | NDT is non-destructive testing. Requirements as outlined in step 5.3.6. | |||
| 46 | What bolting is used between valve 3 and the plate? Does it bolt to the flange below? How is the lower piping supported? | Pool Transition Dropout Chute is through-bolted through the lower plate and the lower flange on FTV-3. Photos to be sent. | |||
| 47 | General | General | Could you please clarify the quality requirements? Typically, work is performed under either NQA-1 (safety-related) or commercial (non-safety-related) standards. Would a graded approach to NQA-1 be acceptable? | NCNR is not held to NQA-1standards and is not required to use items with commercial grade dedication. A graded approach to NQA-1 is likely to meet or exceed all requirements of the SOW, however may result in un-necessary costs. | |
| 48 | General | General | Regarding the mock task order, should we leverage our RP license structure, or will we be using NIST’s license? | This will be under NIST's license. | |
| 49 | General | General | Does NIST have a preferred radioactive waste disposal partner or company? | The contractor may use their own preferred partner. | |
| 50 | General | General | Will the fuel transfer tube be accessible via the reactor vessel? Specifically, will the cover be open at the top, or can it be opened during the mock task order project? | For purposes of this mock task order, there is no need to access the top of the chute. It should be assumed the NCNR would plug the top of the chute to isolate the work area from the reactor vessel. | |
| 51 | General | General | Would NIST consider granting a two-week extension to the proposal deadline? | NIST has extended the proposal due date to no later than 5pm, Friday, March 14, 2025. |
