Dear Mr. Denise:
Post Accident Backup Sampling Capability The Omaha Public Power Dietrict has completed an evaluation of its post accident backup sampling capabilities, as identified in Open Item 8135-02 contained in an IE Inspection Report dated May 4, 1982.
The purpose of this etter is to provide the results of that evaluation.
Using the guidelines of NUREG-0737, Item II.B.3, the District is establishing the onsite radiological and chemical analysis capabi-lity to provide, within a three hour time frame, results for re-actor coolant and containment atmosphere samples.
The method is a remotely operated, semi-automatic on-line system installed as a post accident sampling system (PASS) and as described in letters from W. C.
Jones to R.
A.
Clark dated December 3, 1982 and April 15, 1983 and in a letter from W.
C. Jones to J.
R.
Miller j
dated December 21, 1983.
Since in-line monitoring is used as the primary method for providing sampling and analytical capability, the District is finalizing the development of its procedures for utilizing grab sample and analysis as a backup method.
This method will utilize the Fort Calhoun Station radiochemistry labo-ratory and includes the analysis of diluted and low (radioacti-vity) level undiluted grab samples.
l As you are aware, the District has investigated additional offsite capabilities.
The radiochemistry laboratory at Nebraska Public Power District's Cooper Nuclear Station has been identified as a possible analysis facility.
The Cooper Nuclear Station laboratory has excellent features, but distance constraints prevent full com-pletion of analysis within a three hour period.
Sample and analy-sis drills conducted over the past several months demonstrate ap-proximately six hours are normally required for this task.

Mr. Richard P.
Denise LIC-84-099 Page Two District intends to utilize the Cooper Nuclear Station laboratory as an offsite facility only for analysis of a long term nature and in'the event the Fort Calhoun laboratory becomes uninhabitable.
Therefore, please be informed that the District has completed the evaluation of the post accident backup sampling capabilities.
Based on that evaluation, tne vistrict determined that upon system operability, the District's PASS and the backup grab sample and analysis capabilities provide compliance with the requirements of NUREG-0737, Item II.B.3 and should be sufficient to close open Item 8135-02.
Sincerely,
}
