SUBJECT:
EVALUATION OF ALTERNATIVE EXAMINATION 99-0-001 FOR ARKANSAS NUCLEAR ONE, UNIT NOS.1 AND 2 (TAC NOS. MA5146 AND MA5147)
Dear Mr. Hutchinson:
By letter dated April 1,1999, Entergy Operations, Inc., submitted Alternative Examination 99-0-001, requesting relief from the expedited examination of containment required by Title 10 of the Code of Federal Reaulations (10 CFR) Section 50.55a(g)(6)(ii)(B) and the requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code)Section XI. To comply with the expedited examination of containment requirements of 10 CFR 50.55a(g)(6)(ii)(B), visual examinations of Class MC (and metallic liners of Class CC concrete components) must be performed in accordance with the requirements of Subsection IWE and visual examinations of Class CC (concrete components) must be' performed in accordance with the requirements of Subsection IWL.
t You requested authorization of an alternative examination pursuant to 10 CFR 50.55a(a)(3)(i) or (ii). An alternative to Code requirements was proposed that uses a combination of character-and workmanship-based samples to determine the resolution required to ensure that indications that might challenge containment integrity are detectable. Paragraph IWL-3111, Acceptance of Concrete, requires that the Responsible Engineer determine what surface conditions are acceptable and ensure there is no evidence of damage or degradation sufficient
- to warrant further evaluation or repair. Therefore, your Responsible Engineer will identify the minimum flaw size (indications of interest) required to be detected. For remote visual examinations, procedures and equipment used will be demonstrated to be capable of detecting and resolving these indications. A record of the demonstration performed will be maintained.
The staff has reviewed and evaluated the information in your request and finds that your proposed alternative provides an acceptable level of quality and safety. Therefore, this proposed alternative is authorized, pursuant to 10 CFR 50.55a(a)(3)(i), for the Arkansas
^
Nuclear One, Unit Nos.1 and 2 containment inspections required to be completed, in accordance with 10 CFR 50.55a(g)(6)(ii)(B), by September 9,2001.
