SUBJECT:
-NOTICE OF VIOLATION DATED MARCH 9, - 1992 -
l 3 This acknowledges your letter received April 8, 3992, in response to our letter dated March 9,1992, transmitting a Notice of Violation and other concerns identified during our January 27 and 28, _19921r.spection. This
-also refers to the telephone conversation between Mr. Slawinski and myself and you on May 1,1992, regarding the contents of this letter. During the-
-telephone conversation, we informed you that our response to your April 8, 1992 -letter, regarding certain fire protection concerns addressed in our LConfirmatory-Action Letter dated January 17, 1992, will be forthcoming
-under' separate cover.
-After reviewing'your_ letter and its. exhibits, we agree with your conclusion Lthat-the item' described in the Notice of Violation does not constitute a violation. The calculations and tabulations provided in exhi'*t 1, or its equivalent, were not provided to our inspector during the ins,.<ction.
-Accordingly, we will adjust our records to reflect that no violation of regulatory' requirements _ occurred.
We have'no further questions at-this time concerning your plans to conduct: -
(1) volumetric flow rate measurements of the exhaust system; (2) periodic operability checks of the blower control, interlock and alarm systems, electrical relays and of the air diversion system;'(3)' modifications to the hot cell exhaust and hot area room air exhaust air sampling system to provide isokinetic' sampling of-both effluent streams; and (4) neutron energy measurements and related dose evaluations.
Although.we acknowledge that.the ASME N510-1989 standard was developed primar.ily for testing _ air treatment systems of nuclear _ power plants, the
. concepts and criteria in the standard.are= applicable to testing air treatment
- systems designed and-built to criteria other than ASME N509 specifications.
Consequently., portions of the standard-are applicable to air _ cleaning systems for all; nuclear applications. The NRC requires' reasonable assurance that airborne ef flue'nt releases from your facility will not exceed appl _icable
- limits should an unanticipated _ problem occur._ To provide this assurance, your facility is_ equipped-with a dedicated HEPA fil.tered exhaust ventilation system. However, the filtration system has not undergone in place testirig to ensure its leak tightness and that the integrity of the HEPA filters have

Therefore, it is highly desirable that at least the final filters in the hot area and hot cell exhausts be in place tested for leak.ge and integrity using current service flow rates,-as you suggest on Page 11 of your letter received April 8, 1992. These tests can be conducted using ASME N510 or equivaient procecures.
Your evaluations and corrective actions taken in response to our inspection findings will be exarined during future inspections. No response to this letter is required.
Sincerely, William H. Schultz, Chief Nuclear Materials Inspection Section 1 cc w/ltr dtd April 8, 1992:
