****This is a REQUEST FOR INTEREST ONLY! This request does not constitute a request for proposal, request for quote, or invitation for bid. The intent of this request is to identify potential offerors for mark research purposes only*****

Savannah River Nuclear Solutions, LLC (SRNS), which manages and operates portions of the Savannah River Site (SRS) under a Department of Energy (DOE) prime contract, solicits expressions of interest from potential suppliers who have a strong background in Exhaust Stack and/or Industrial Chimney inspections.

The SRS complex is located approximately 15 miles south of Aiken, South Carolina and is 310 contiguous square miles.

Request for Information (RFI)

1. Revised 10/31/22 – see Scope Summary, first paragraph, changed approximate room temperature.

2. Revised 11/09/22 – see Scope Summary, added third paragraph.

Scope Summary:

Provide an internal stack inspection at SRS for an active stack. The stack has a flow rate of 111,121 cfm and exit velocity of 2,220 fpm. The temperature of air flow exiting the stack is approximately room temperature (69 degrees F to 72 degrees F). The stack is 200 feet high.

296-H is comprised of a 183’-8” concrete chimney without stack liner sitting atop a reinforced concrete foundation. The chimney varies in size and thickness from 12’-11 7/8” outer diameter with 10” thickness at its base, reducing down to outer diameter of 11.04’ and 6” thickness at 90 feet, and then maintains 6” thickness while reducing in size to an outer diameter of 9’-0”. The stack foundation is 25’-0” tall in total, with the bottom 4’-0” comprised of a 36’-0” wide octagonal Footing.

The chimney that needs to be inspected does not have ladder access to the top for an internal inspection, however, a crane is an option that could be used to lower equipment into the stack. Pictures nor drawing of the stack are not available at this time.

1. During the inspection the stack flow rate and velocity can be reduced to 32,360 cfm and the air exiting the stack would be approximately 647.2 ft/min.

2. Potential for radiation contamination on equipment. However – SRNS will have our Radiological Team during planning, and any work being done.

3. Ability to perform work scope by not “touching” stack (i.e. no climbing of the stack, no attaching equipment on the stack, etc.).

4. Provide report and pictures/videos of stack to determine status of structure.

A supplier's response to the RFI does not guarantee they will be selected to participate in the RFP.

Suppliers responding to this RFI shall include evidence of the following:

1. Overview of how the subcontractor intends to perform a non-destructive and/or visual inspection on an active stack with similar specs.

2. Examples of past performance in stack inspection. For example, a report of an inspection that was previously completed.

E-mail response addressing Items 1 and 2 above shall be submitted by 5:00 p.m. est. on 11/28/22 to Barbara McCarty at barbara.mccarty@srs.gov.
