II.1.4) Short description

Sellafield Ltd, through the Decommissioning and Nuclear Waste Partners (DNWP) Framework opportunity, is seeking to bring together five partners across four Lots to provide a full suite of expertise and support to deliver decommissioning activities and projects, including asset care. Delivery will be across nuclear facilities on the Sellafield licenced site that are in mix of states including operational, post operation clean out (POCO), decommissioning and demolition. Consequently, the scope of work for the DNWP Framework will include construction delivery, demolition related works, associated technical services (including safety case and design) and waste management with the scope aligned across the following four Lots:

• Lot 1 Remediation:
o Partner 1 - within High Security Areas
o Partner 2 - outside High Security Areas
• Lot 2 Pond Retrievals Partner
• Lot 3 Silos Retrievals Partner
• Lot 4 Integrated Nuclear Waste Partner

II.2.4) Description of the procurement

Lot 1 - two Remediation Partners (Sellafield’s intention is that one of the Remediation Partners will be required to work inside of the high security area (“HSA”) and the other Remediation Partner will work outside of the HSA);

Remediation is about cleaning up the Sellafield site over the next century as safely and cost-effectively as possible. As an asset reaches the end of its operational life, remediation addresses the nuclear, radiological and conventional risks through post-operation clean-out, decommissioning, demolition and land remediation. The focus of waste informed nuclear decommissioning up to 2040 includes clearing redundant buildings to make land available for beneficial re-use and preparing to decommission the UK’s oldest nuclear reactor complexes and nuclear fuel handling facilities.
Lot 1 will consist of two Remediation Partners. The Remediation value stream will have a growing scope as more and more of the Sellafield site moves from operations into remediation and decommissioning. This will be reflected in a growing investment over the lifetime of the DNWP framework, subject to annual public sector funding constraints.

Section VI. Complementary information

VI.1) Information about recurrence

This is a recurrent procurement: No

VI.3) Additional information

The estimated value of the DNWP Framework is stated at II.1.5.1 which is the upper end of the anticipated range of £3.8bn-£4.6bn for the 15-year framework duration. This range recognises the challenge of estimating the total value of a framework arrangement with longevity and that has the potential to be impacted by the UK Nuclear strategy, the strategy of the Nuclear Decommissioning Authority and associated HMG funding, the strategy of Sellafield Ltd as well as the potential variability arising from factors including, but not limited to, the conditions of the nuclear facilities, costs, inflationary impacts, options for technical solutions and innovation etc.

The DNWP Framework will be the successor to the existing Decommissioning Delivery Partnership (DDP) framework which will expire in March 2026, albeit task and project delivery may run beyond the DDP framework expiry. The DNWP Framework will have an initial mobilisation period and it is anticipated that in line with the call-off contract arrangements that delivery of task and project activity may run beyond the expiry date of the DNWP Framework.

As stated in section II.1.4, and as further developed in the procurement pack (accessed via the Atamis portal), the capabilities of each of the DNWP Partners are identified in the scope. It is anticipated that the Partners will be required to put in place subcontracting arrangements to support delivery of the scope that forms part of this procurement and that the subcontracting arrangements will not be subject to competition via the Find a Tender service. Sellafield Ltd also has in place, and through the term of the DNWP Framework will procure, site-wide contractual arrangements which may be utilised to support the delivery by the Partners.

Please refer to Selection Stage and Award restrictions in the SQ and ITT instructions.

Sellafield Ltd supports the One NDA way of working and may share relevant information related to the DNWP Framework with members of the NDA group. Additionally, in the exceptional circumstances, (which are defined within the DNWP framework agreement) that a DNWP Partner is required to support at another site licenced company within the NDA group then with prior approval of the DNWP Programme Board a DNWP Partner may be provided with relief to a key performance indicator where such deployment impacts upon a DNWP programme.

Sellafield Ltd is committed to delivering social impact with the successful DNWP Partners required to contribute to our strategy.

The DNWP contract opportunity has been developed with input from market engagement activity which has been driven through prior information notices (“PIN”). Information related to this engagement can be found in the DNWP archive within Atamis (ATAMIS portal ref C13375):
