# AnM.7: Micro-model "Experimental Shadow Value"

**Relevance:**

The model is used in FenRIAM to estimate the monetary value (cost) of the access time offered to the users of the RI.

**Description:**

**Cost1** is based on the sum of total construction and operation costs.

**Cost2** uses only the total operation costs over the RI's lifetime.

**Cost3** subtracts the staff costs from the total RI costs.

Upgrading and decommissioning costs may be added to the costs in Cost1 and Cost3 in order to obtain a better estimate, if available.

**Procedure:**

- Collect the data listed in the description of indicator S+T.1.5
- Calculate the operation costs OpCo by multiplying the annual operation costs by the estimated lifetime LifeT of the RI in years
- Calculate the staff costs for operation by multiplying the annual staff costs for operation by the lifetime LifeT of the RI in years.
- Sum the staff costs for operation and the staff costs for construction in order to obtain the total staff costs StCo.

- Calculate the available number of user access hours AvH over the lifetime of the RI by multiplying the number of experimental equip-ments N with the average functioning coefficient α, the planned num-ber of annual user access hours UserH and the RI's lifetime LifeT

AvH = α•N•UserH•LifeT

Alternatively sum over all equipments i with average functioning coefficients αi and annual user access hours UserHi

AvH = LifeT • ∑ αi• UserHi

- Calculate Cost1, Cost2, and Cost3 from the formulas in the description. If desired, use the sum of construction, upgrading and decommissioning costs instead of construction costs only.

**Data sources: **

- Interviews with suitable experts from the project (e.g. scientific project manager, responsible manager for user relations)
- Document analysis of project documents or websites

**Definitions:**

α describes the fraction of the planned annual user access hours, during which the equipments are really functioning and can thus be used to perform research.
