About the company
Nuclear Safety & Technology Services LLC (doing business as Nsts) operates exclusively as a subcontractor delivering nuclear criticality safety and environmental remediation support to the federal government, with all three recent awards placed under Amentum Technology as the prime contractor.
Nsts is a for-profit limited liability partnership headquartered in Palm City, Florida, with a remediation-services specialty. The vendor has no prime contracts or IDVs in the source data; instead, it specializes in technical support and project management for nuclear facility remediation and criticality safety work. The company's federal customer base is small and concentrated: the Department of the Army Corps of Engineers and the Department of the Army account for 100% of the three recent awards tracked in the source, representing $694 thousand in combined obligations.
All three awards flow through a single parent vehicle — Indefinite Delivery Contract W912P417D0001 — with task orders issued between July 2024 and August 2025. Representative work includes a July 2024 modification providing pre-remediation supervision, management, training, and testing support for the Shallow Land Disposal Area (SLDA) Remediation Site in Vandergrift, Pennsylvania (Mod 06, $303,012), a follow-on October 2024 extension to that same site work (Mod 07, $184,178), and an August 2025 onsite nuclear criticality safety support task for the SLDA site ($206,864). The three awards cluster around a single customer need — SLDA remediation in Vandergrift — executed under a stable contract with Amentum.
Service Contract Inventory data captured one SCI-reportable record in FY2022, reflecting 1.8 FTEs delivered to the federal government in that fiscal year as a named subcontractor. Activity in the source footprint shows two awards in 2024 and one in 2025, representing recent work but limited visibility into current staffing or pricing posture. As a 100%-sub vendor with no prime capability in the source, Nsts operates as a specialized technical feeder to larger remediation and environmental services primes, with Amentum Technology as its sole named federal customer relationship. The vendor's positioning is narrow — nuclear safety and facility remediation expertise — without visibility into diversification across other prime contractors or agencies outside Army Corps of Engineers and Army domain.
