The following design features and administratively controlled limits are necessary to
ensure the criticality safety of the system. Operation safety limits are set in the Plant Safety
Document (PSD) and the Technical Specifications (TS/S) associated with that operation.
7.1 Design Features
The BORAX V Superheater fuel has uranium gram loadings and enrichments at or below
those listed in this evaluation.
The BORAX V Superheater fuel has maintained its structural integrity, due to its material
compositions, such that its physical form does not grossly deviate from that listed in this
7.2 Administrative Limits
Each storage bucket stored on the basin floor will be limited to three BORAX V Superheater
Storage buckets suspended from the monorail system will be limited to four Borax V
Superheater assemblies provided the buckets are preventively rigged to avoid dropping to the
basin floor. If the remaining hanging buckets are not preventively rigged, the limit per bucket
will be set at three BORAX V assemblies.
A row containing storage buckets placed on the floor will be limited to buckets containing
only BORAX V Superheater fuel assemblies. No other fuel types will be allowed in this row.
The summary and conclusions from this evaluation are given below:
· Storage buckets that contain three (3) BORAX V Superheater fuel assemblies may be
stored on the floor of the north and middle basins without any restrictions upon spacing
between the storage buckets.
· Only BORAX V Superheater peripheral and central assemblies were considered in the
evaluation. The storage of a single row of buckets containing BORAX V Superheater
fuel assemblies was evaluated. Interaction with other fuel types within the row was not
considered since other fuel types in a single row will be restricted through administrative
