Some major milestones in the UFSAR Rebaseline Project have been achieved.
To date, the existing UFSAR has been reformatted to Regulatory Guide 1.70 standards.
Information gathering is near completion and contracts have been awarded to Architect / Engineer firms to assist in the rewrite of the UFSAR.
Finally. paral _lel efforts to improve the quality of the UFSAR_during the interim period prior to the issuance of rebaselined UFSAR continues.
The responsibility for the UFSAR has been transferred to the Regulatory Assurance i
Department of the. Station,_ procedures have been upgraded and a dedicated individual has been assigned to the update function.
These enhancements
-should further improve the quality of future updates to the Final Safety Analysis Report-(FSAR).
This submittal'is not intended to. satisfy the requirement for an annual I
update to the FSAR which reflects all changes made in the facility or procedures. described in the FSAR during 1990.
