## Project summary
An environmental authority opinion dated 18 December 2025 concerns planned additions to INB 116 (UP3-A) at Orano La Hague for compacted CSD-C and vitrified CSD-V waste. The opinion describes E/ECC2 as adding capacity for 24,968 CSD-C packages. E/EV/LH3 comprises two planned pits, each with capacity for 4,212 CSD-V packages; the opinion states a resulting site capacity of 33,300 CSD-V.
The schedule reported in the opinion planned E/ECC2 construction for 2026–2032, with commissioning in 2034, and E/EV/LH3 construction for 2027–2037. Pit 70 was scheduled to enter service in September 2032 and pit 80 in 2037. A public inquiry was planned for 2026. The environmental authority’s opinion is advisory, neither favorable nor unfavorable, and does not authorize the project.
The authority identifies long-term releases, human health, climate vulnerability and cumulative site impacts as concerns, and requests further analysis. These recommendations are not evidence that the requested work has been completed.
This account is based on selected portions of the opinion dated 18 December 2025 and does not establish later project outcomes.
## Evidence limits and unknowns

- The selected portions do not identify the applicant or maître d’ouvrage by name, a contractor, procurement plan, budget, financing, or supplier selection.
Current purchasing availability: unknown.
Source-dated plans do not establish current progress or available supplier packages.

Derived from the reviewed scope statement; delivery stage remains unclassified.
A substantial modification of INB 116 involving added capacity for two waste streams: compacted waste packages (CSD-C) and vitrified waste packages (CSD-V). The facilities are described as additions to existing installations within the site's already fenced and industrialized perimeter, with no outward site expansion.

## Ecology
The environmental review identifies long-term control of radioactive and chemical releases, human health, climate vulnerability and cumulative effects with other site operations as key concerns. It reports very low chemical or radioactive releases from the new facilities, but says some chemical releases at the wider La Hague site are near or above concern thresholds and recommends better treatment of release variability, cumulative or interactive effects, and Natura 2000 impacts. It also calls for fuller assessment of prolonged storage, climate-related temperature conditions and concrete-temperature exceedances for E/EV/LH3, and for cumulative project schedules and traffic/material flows. These are review findings and requests for further analysis, not findings that the recommended work has been completed.

## Activity
Temporary storage of conditioned radioactive waste pending its eventual transfer to the Cigéo geological disposal facility. The compacted CSD-C stream consists principally of metal components from fuel assemblies; the vitrified CSD-V stream contains vitrified fission-product waste.

## Regulatory
The dossier includes an application for authorization of a substantial modification to INB 116 and an environmental assessment. The opinion describes a public inquiry planned for 2026, after which the application is to be sent to the minister responsible for nuclear safety; following an ASNR opinion, a report to the Prime Minister is to propose authorization by decree. The environmental authority's opinion is advisory: it is neither favorable nor unfavorable and does not itself authorize the project.
