ISRAM

ISRAM is the Swiss standard for radioactive waste and material: in service at every Swiss nuclear power plant, at the interim stores ZWILAG and ZWIBEZ, at the Paul Scherrer Institut and at NAGRA. In production since 1989 — and still developed further with the ISRAM user group, which brings all its users together.

From raw waste to package

Every waste package starts as a package type: raw waste, conditioning, container, filler, overpack. ISRAM builds each type from reusable parts and calculates mass, volume and density on the way. The result supports ENSI’s approval of conditioning processes and NAGRA’s assessment of suitability for disposal.

Know where everything is

Every package and container is recorded — entered by hand or imported straight from drum-measurement systems. ISRAM tracks each one through treatment, transport and storage, down to its position in the store, visualised in 3D and coloured by dose rate, activity or owner.

Know what is inside

Not every nuclide can be measured. ISRAM completes the nuclide inventory from reference vectors and calculates activity, decay, heat output and dose rate for any date — today, at transport, or decades from now.

Move it without paperwork

Every transport of radioactive material falls under the European ADR agreement, class 7. ISRAM runs the required calculations and generates every transport document.

Report on demand

Type, quantity and composition of everything in storage — at any moment. The monthly, quarterly and annual reports for ENSI and the safeguards reports for the IAEA are generated by ISRAM.

Plan the repository

ISRAM links the sites, ZWILAG and NAGRA: package types and inventories move between them as data, not as documents. NAGRA uses ISRAM to model future waste streams — the basis for Switzerland’s deep geological repository.
