Storage (ISS) in 2012. ISS consists of the removal of the fuel storage basin, ancillary support facilities, and most portions of the shield wall that surround the 105-N Reactor. In addition, the 109-N Heat
Exchanger Building was removed up to the steam generator cells. A new steel roof was installed over the remaining structures. Before and after pictures are found in the facility status change form. Final room status report of the current as-left condition of accessible rooms in the ISS has been documented.

It was partially moderated with graphite, but had a negative void coefficient due to also using moderation from the coolant water, meaning it was thermally stable.
