U.S. Nuclear Regulatory Commission (NRC) Management Directive 8.8, "Management of Allegations," dated November 15, 2010, requires the Agency Allegation Advisor to prepare an annual report for the Executive Director for Operations that analyzes allegation trends. This annual report fulfills that commitment by providing national, regional, and site-specific trend analyses. In addition, significant staff activity in calendar year (CY) 2011 involving the Allegation Program and related policies are discussed in this report. The reports also includes discussion on the development of enhanced guidance for the NRC staff handling allegations, and for the public engaged in the program, and correlations between safety culture survey scores and allegation data identified by the NRC's Office of Nuclear Regulatory Research. Lastly, the allegation staff continues to implement the agency-sponsored alternative dispute resolution process for discrimination allegations (Early ADR). Twenty-one percent of the discrimination cases raised in CY 2011 offered Early ADR reached settlement.
