Inventory Batcher (Generic)

Library:
Fissile Facility Flow Modeler/Common

Description

The generic inventory batcher creates discrete entities from an input flow according to user defined settings in the dialog (i.e., creates a batch). This block is similar to the generic flow batcher with the key difference that this block will not output while flow is entering. It is designed to be used with inventories, rather than flows, and expects that there will be periodic, rather than continuous, additions to the inventory will be made. The generic inventory batcher uses a isotope or element (or other keyword, see overview) combined with a target size to create an entity. The residual size specifies the minimum amount of collected flow that is left behind when the batch entity leaves. Effectively, this block outputs an entity that is output target size for the batch basis once the total inventory of batch basis reaches output target size + residual size.

When a new discrete entity is created, it must be removed from the block’s inventory. This can be done near-instantaneously or over some period of time, depending on user specification. The speed at which the entity leaves the block is controlled by the inventory pulse width parameter. This parameter subtracts an integral pulse, which is equal in size to the newly created discrete entity, from the inventory to reflect that material has left the block. Simultaneously, the entity is delayed for the same duration as the inventory pulse width to ensure accurate process material balance.

Mask dialog options

Reduction multipliers : float

The fraction by which to reduce the input signal for a specific species. These can be added or removed using the buttons under the table. Species specification can are to be elemental or isotopic in nature without any hyphenation; e.g.; h or cs137. Reduction multipliers are expected to be floats \(\in[0,1]\) with 1 indicating all of the species is removed and 0 that none is removed. By default, species not entered in this table will be assumed to have a value of 0.

Example:

Isotope or Element	Reduction Multiplier
h3	0.10
c12	1.00

Here, 10% of h³ and 100% of c¹² is removed from incoming entities, In(C), and placed into the Rmvd(C) entity.

Ports

In(C) : signal

Signal to modify. Has shape [1677, 1] that represents the different isotopes tracked by F3M

Outputs

Res(D) : signal

Residual signal after reduction multipliers have been applied.

Rmvd(D) : signal

Signal representing the component that was removed from the original signal.

Inv : signal

Continuous inventory signal with shape [1677, 1]. Updated when entities enter or leave the block. Both Res(D) and Rmvd(D) is removed from inventory when leaving the block.
