Technetium Littoral Cell

The Irish Sea is not a boundary to the Sellafield complex, but an active, uncontained biogeochemical extension of its waste storage architecture.

Intertidal sensor array logging simulated radionuclide flux on the Sellafield foreshore. · motion: rhythmic, tidal extrusion of contaminated data

wall text

This installation interrogates the Irish Sea as an open-air hydrological extension of the Sellafield nuclear facility. By deploying an intertidal array of autonomous sensors, the work transposes in situ gamma spectrometry and longshore sediment transport modeling into a live field experiment. As tidal cycles submerge the coastal mudflats, the instrumentation registers simulated radionuclide migration through benthic sediments and bladderwrack (*Fucus vesiculosus*). The project reframes environmental dispersal models as continuous telemetry, tracking Technetium-99 uptake across coastal compartments and presenting marine erosion not as passive dispersion, but as an active metabolic component of the facility's waste architecture.

anchor facts used

Sellafield historically discharged Technetium-99 (Tc-99) into the Irish Sea, which actively bioaccumulates in local marine flora like Fucus vesiculosus (bladderwrack).
The Cumbrian coastline is undergoing active erosion, threatening to eventually expose legacy nuclear waste infrastructure.
A subtidal mud patch in the eastern Irish Sea acts as a long-term sink for Sellafield-derived plutonium and americium.

mechanism

In situ gamma-ray spectrometry — Deploying a grid of autonomous, tide-powered scintillators along the Sellafield foreshore to continuously log real-time ambient radiation levels in the shifting coastal sediment.
1. Sampling the source compartment.
Longshore drift sediment transport modeling — Mapping the movement of irradiated sand grains southward using bespoke acoustic Doppler profilers disguised as offshore lobster pots anchored to the seabed.
2. Calculating the transit rate.
Bioconcentration factor (BCF) calculation — Harvesting Fucus vesiculosus along the drift line, drying it, and plotting its Tc-99 content against the source telemetry to index the ocean's metabolic absorption.
3. Measuring biological uptake.
Pharmacokinetic compartmental modeling — Driving a continuous, motorized mechanical plotter that physically extrudes a shoreline-shaped wax barrier corresponding to the shifting isotopic burden of the coastal ecosystem.
4. Outputting the multi-compartment state.

lineage

James Acord, 'The Hanford Reach' — Extends Acord's ambition to sculpt with nuclear materials by substituting direct handling with automated, landscape-scale biogeochemical biomonitoring.
Mark Lombardi, 'Global Networks' — Translates Lombardi's hand-drawn financial topologies into physical, automated transport networks of radionuclides migrating through ecosystems.
Susan Schuppli, 'Material Witness' — Operationalizes Schuppli's concept of matter recording its own history by forcing the coastal erosion to physically document its isotopic displacement.

curatorial qa (machine verdict, unedited)

SCORE 3/5 after 2 attempt(s)
READS: Tidal foreshore instrumentation linked visually to the nuclear complex, with sensor nodes activating as the surf washes over sediment.
FAILS: Sediment transport dynamics and biological uptake in marine flora remain largely conceptual rather than visibly demonstrated across the tidal cycle.
