The enclosure of this letter provides the staffs revised projected schedule for the DNPS SLRA review. The staff will strive to meet the milestones ahead of the revised schedule whenever feasible.

Based on the current status of the review and implemented efficiencies, the staff estimates that the review of the SLRA will take approximately 12,200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> to complete. This reflects an estimate of 6,950 hours0.011 days <br />0.264 hours <br />0.00157 weeks <br />3.61475e-4 months <br /> for the safety review and 5,250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br /> for the environmental review.
