May 26,1999 MEMORANDUM TO: William D. Travers Executive Director for Operations FROM: AndrewJ. Murphy M , Mary Senior Technical Advisor for E h Sciences and Structural Engineering Division of Engineering Technology Office of Nuclear Regulatory Research

SUBJECT:

DPO ON AMENDMENT NO.7 TO CHEMETRON'S LICENSE FOR BERT AVENUE in a memorandum dated November 3,1998, Dr. Ross Landsman of the Decommissioning Branch, Division of Nuclear Materials Safety, Region Ill, expressed his differing professional opinion (DPO) regarding two issues associated with granting Amendment No. 7 to Chemetron's license for Bert Avenue. Heidentified the two issues as: (1)" agency policy with respect to approving a license amendment prior to the NRC receiving, reviewing, and approving the licensee's technical basis", and (2) " the technical issues that were not satisfactorily resolved."

By your memorandum of January 19,1999, you appointed Dr. Yong Kim and myself as Chairman to an ad hoc panel to review Dr. Ross Landsman's DPO. Dr. Carl Costantino, a private consultant, was appointed as the third member of the panel; his selection was suggested by Dr. Landsman.

The DPO Panel reviewed a collection of documents compiled by Dr. Landsman in support of his opinion; another collection of documents was provided by Mr. Timothy Johnson, LLDP/DWM/NMSS, in support of the decision to grant the license amendment. The Panel conducted personal interviews with Dr. Landsman, Region lil, and Mr. Hickey, Mr. Johnson, and Mr. Timothy Harris (all three from LLDP/DWM/NMSS) with regard to the technical issue; and Dr. Landsman, Mr. Johnson, and Mr. Hickey with regard to the process issue.

The DPO Panel has completed its review and the report is attached.

400 Trial Surfaces Have Been Generated. t 20 Surfaces initiate From Each of 20 Points Equally Spaced Along The Ground Surface Between X = .00 ft.

and X = 32.00 ft.

Each Surface Terminates Between X = t10.00 ft.

and X = 200.00 ft.

Unless Further Limitations Were imposed. The Minimum Elevation At Which A Surface Extends is Y = .00 ft.

10.00 ft. Line Segments Define Each Tnal Failure Surface.
