SUPPLEMENTARY INFORMATION:
I. Introduction
Regulatory guides may be withdrawn by the NRC when their guidance
no longer provides useful information or is superseded by technological
innovations, congressional actions, or other events. The NRC is
withdrawing RG 1.77 because its guidance has been incorporated into RG
1.236, ``Pressurized-Water Reactor Control Rod Ejection and Boiling-
Water Reactor Control Rod Drop Accidents'' (ADAMS Accession No.
ML20055F490). The basis for withdrawal is found in ADAMS under
Accession No. ML20084N202.
II. Further Information
The withdrawal of RG 1.77 does not alter any prior or existing NRC
licensing approval or the acceptability of licensee commitments to this
RG. Although RG 1.77 is withdrawn, current licensees may continue to
use it, and withdrawal does not affect any existing licenses or
agreements. However, after the withdrawal of RG 1.77, licensees should
use RG 1.236 in future requests or applications for NRC licensing
actions related to the guidance in RG 1.77.
Dated: June 16, 2020.
