      FOREWORD

      
      

      This Standard covers the requirements for in-service testing of nuclear safety-related air-treatment, heating, venti- lating, and air-conditioning systems in nuclear facilities that are designed, built, and acceptance tested in accordance with ASME AG-1.

      This Standard provides a basis for the development of test programs, in-service test procedures, and corrective action requirements.

      In 1971, what is now the Committee on Nuclear Air and Gas Treatment was organized as ANSI N45.8 to develop standards for high-reliability, air-cleaning equipment for nuclear facilities and corresponding tests to confirm perfor- mance of the equipment. Two standards, ASME N509 and ASME N510, were published in 1975 and 1976, and updated in 2002 and 2007, respectively. In 1976, under the accredited organization rules, the Committee was reorganized as the ASME Committee on Nuclear Air and Gas Treatment. The scope of responsibility was broadened to include the devel- opment of codes and standards for design, fabrication, inspection, and testing of air-cleaning and air-conditioning compo- nents and appurtenances, as well as air-cleaning components used in engineering safety systems in nuclear facilities. The current assignment is to produce code documents, maintain ASME N509 and ASME N510, and develop and maintain ASME N511.

      The first edition was approved by the ASME Committee on Nuclear Air and Gas Treatment and the ASME Board of Nuclear Codes and Standards, and was subsequently approved as an American National Standard by the American National Standards Institute on October 30, 2007.

      This revision was approved by the American National Standards Institute on November 1, 2017.

   https://go.asme.org/Inquiry

   
   

   Proposing Revisions. Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Standard. Approved revisions will be published periodically.

   The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation.

   
   

   Proposing a Case. Cases may be issued to provide alternative rules when justified, to permit early implementation of an approved revision when the need is urgent, or to provide rules not covered by existing provisions. Cases are effective immediately upon ASME approval and shall be posted on the ASME Committee web page.

   Requests for Cases shall provide a Statement of Need and Background Information. The request should identify the Standard and the paragraph, figure, or table number(s), and be written as a Question and Reply in the same format as existing Cases. Requests for Cases should also indicate the applicable edition(s) of the Standard to which the proposed Case applies.

   
   

   Interpretations. Upon request, the Standards Committee on Nuclear Air and Gas Treatment (CONAGT) will render an interpretation of any requirement of the Standard. Interpretations can only be rendered in response to a written request sent to the Secretary of CONAGT.

   Requests for interpretation should preferably be submitted through the online Interpretation Submittal Form. The form is accessible at https://go.asme.org/InterpretationRequest. Upon submittal of the form, the Inquirer will receive an automatic e-mail confirming receipt.

   If the Inquirer is unable to use the online form, he/she may mail the request to the Secretary of CONAGT at the above address. The request for an interpretation should be clear and unambiguous. It is further recommended that the Inquirer submit his/her request in the following format:

   
   

   Subject: Cite the applicable paragraph number(s) and the topic of the inquiry in one or two words. Edition: Cite the applicable edition of the Standard for which the interpretation is being requested.

   Question: Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. Please provide a condensed and precise question, composed in such a way that a “yes” or “no” reply is acceptable.

   Proposed Reply(ies): Provide a proposed reply(ies) in the form of “Yes” or “No,” with explanation as needed. If entering replies to more than one question, please number the questions and replies.

   Background Information: Provide the Committee with any background information that will assist the Committee in understanding the inquiry. The Inquirer may also include any plans or drawings that are necessary to explain the question; however, they should not contain proprietary names or information.

   Requests that are not in the format described above may be rewritten in the appropriate format by the Committee prior to being answered, which may inadvertently change the intent of the original request.

   Moreover, ASME does not act as a consultant for specific engineering problems or for the general application or understanding of the Standard requirements. If, based on the inquiry information submitted, it is the opinion of the Committee that the Inquirer should seek assistance, the inquiry will be returned with the recommendation that such assistance be obtained.

   ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee or Subcommittee. ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity.

   
   

   Attending Committee Meetings. CONAGT regularly holds meetings and/or telephone conferences that are open to the public. Persons wishing to attend any meeting and/or telephone conference should contact the Secretary of CONAGT.

   IN-SERVICE TESTING OF NUCLEAR AIR-TREATMENT, HEATING, VENTILATING, AND AIR-CONDITIONING SYSTEMS

   
   

   1. INTRODUCTION

      1. Scope

         This Standard covers the requirements for in-service testing of nuclear safety-related air-treatment, heating, ventilating, and air-conditioning systems in nuclear facilities.

         
         

      2. Purpose

         The purpose of this Standard is to provide requirements for in-service testing, the results of which are used to verify that the nuclear air-treatment, heating, ventilating, and air-conditioning systems perform their intended functions.

         
         

      3. Applicability

         This Standard applies to the in-service testing of nuclear air-treatment, heating, ventilating, and air-conditioning systems that have been designed, built, and acceptance tested in accordance with ASME AG-1. Sections of this Standard may be used for technical guidance when testing air-treatment, heating, ventilating, and air-condi- tioning systems designed and built to other standards.

         
         

      4. Use of This Standard

This Standard provides a basis for the development of test programs and does not include acceptance criteria, except where the results of one test influence the perfor- mance of other tests. Based on the system design and its function(s), the owner shall develop a test program and acceptance criteria.

Nonmandatory Appendices A, B, C, and D provide addi- tional information and guidance.

Preconditioning for purposes of personnel protection or equipment preservation should outweigh the benefits gained by testing only in the as-found condition. This preconditioning may be based on the equipment manu- facturer’s recommendations or industry-wide operating experience to enhance equipment and personnel safety. This preconditioning should be evaluated and documented prior to the in-service test.

acceptance test: a test made upon completion of fabrica- tion, installation, repair, or modification of a unit, compo- nent, or part to verify to the user or owner that the item meets specified requirements.

adsorbent: a solid having the ability to concentrate other substances on its surface.

adsorber: a device or vessel containing adsorbent.

adsorber bank or filter bank: one or more filters or adsor- bers secured in a single mounting frame, or one or more side-by-side panels containing poured or packed air-treat- ment media, confined within the perimeter of a duct, plenum, or vault cross section, sometimes referred to as a stage.

aerosol: a stable suspension of particles, solid or liquid, in air.

as-found condition: the condition of a component between in-service tests without preconditioning.

challenge: to expose a filter, adsorber, or other air-treat- ment device to an aerosol or gas of known characteristics under specified conditions for the purpose of testing.

challenge aerosol: an aerosol used for in-place leak testing of installed HEPA filter systems.

NOTE: The polydispersed aerosol used for in-place leak testing of systems differs in size from the 0.3 μm monodisperse dioctyl phthalate (DOP) aerosol used for efficiency testing of individual

ð17Þ

1.5

Definitions

HEPA filters by manufacturers. For potential substitutes for DOP,

These definitions supplement those listed in ASME AG- 1, Article AA-1000.

abnormal incident: any event or condition that may adversely affect the function of the nuclear air-treatment, heating, ventilating, and air-conditioning systems.

acceptable preconditioning: the alteration, variation, manipulation, or adjustment of the physical condition of a component before in-service testing for the purpose of protecting personnel or equipment or meeting the manufacturer’s recommendations. This may include routine and scheduled maintenance for optimum equipment and system performance.

reference ASME AG-1, Article TA-2000.

challenge gas: a gas of known characteristics used for in- place testing of adsorbers.

HEPA filter (high-efficiency particulate air filter): a dispo- sable, extended media, dry-type filter enclosed in a rigid casing that exhibits a minimum efficiency of 99.97% when tested with an essentially monodisperse 0.3 μm test aerosol.

in-service test: a test to determine the operational readi- ness of a system or component.
