Subject:  NRC Enforcement Positions for ASME Codes

Dear Group:  I understand that the ASME has been working with the NRC to help clarify the NRC’s endorsement positions for Nonmandatory Appendices, references in Codes to other Codes, certain Subsections in Section III and Code Cases related to certain Codes.  Can you tell me what the status is?  Thanks, George

 

 

Date:  Sunday, 11 March 2007

Subject:  NRC Enforcement Positions for ASME Codes

Dear George:  On January 11.2007, the NRC presented their draft positions as follows:

 

1.  All Nonmandatory Appendices are considered approved for use for the currently endorsed ASME Code Editions and Addenda of Section III (Division I), Section XI (Division I) and the OM Code as listed in 10 CFR 55a.

 

2.  All references in these Codes to supporting Codes such as Section II, Section V and Section IX are implicitly approved for use, up to the latest published versions available.

 

3.  The current endorsement of ASME Section III (Division I) Subsections NE for containments, NF for supports and NG for core support structures are implicitly approved for use, but are not mandatory.

 

4.  Code Cases published for Sections II, V and IX are also implicitly approved.

 

The NRC is expected to publish their final positions soon, but the publication media is unknown at this time.

Subject:  Spent Fuel Transport Package

Dear Group:  in 10cfr 71.43(g), the accessible surface of a spent fuel transport package should not be exceeded 85°C (185°F); for the exclusive use shipment. the problem is i can identify the definition of the accessible surface of package from the description of code, and if there is personal barrier, is the surface of the barrier be defined as accessible surface or not?  yours sincerely, liu zhenling

 

 

Date:  Wednesday, 4 October 2006

Subject:  Spent Fuel Transport Package

Dear Liu:  It would be reasonable to assume that if the “personal barrier” is part of the package, then the accessible surface of the personal barrier would also be included and governed by the requirements of 10 CFR 71.43(g).

Date: Thur, 16 September 1999

Subject: Code of Federal Regulations - 10 CFR 30.35

Dear Group: I would like to know what statutory authority NRC has to impose financial assurance requirements pursuant 10 CFR 30.35 upon entities operating under a 42 USC 2014(e)(1) classification (Cobalt-60). JDAL

 

 

Date: Tue, 28 September 1999

Subject: Code of Federal Regulations - 10 CFR 30.35

Dear JDAL: The referenced 10CFR section states that licensees must provide evidence of financial assurance before they can utilize licensed radioactive sources. I believe the answer to this question is twofold. First, If the license was issued through the NRC, then the NRC has the authority to invoke this requirement. Second, If this requirement is providing an undue financial hardship, then relief can always be sought. If it is a matter of excessive paperwork, then nothing short of a congressional mandate can help. One final thought, ask the NRC. The region would be happy to provide an answer...(no joke here). It might save some problems in the long run. Russ Day

Date: Tue, 4 Aug 1998

Subject: NRC Regulatory Guides

Hello Everyone: I was trying to check the status of three NRC Regulatory Guides in the link provided at this site under Libraries and Reference Sources and found that all three have been withdrawn by the NRC. The guides in question are 1.58 "Qualification of Nuclear Power Plant Inspection, Examination, and Testing Personnel (Rev. 1)", 1.88 "Collection, Storage, and Maintenance of Nuclear Power Plant Quality Assurance Records (Rev. 2)", and 1.123 Quality Assurance Requirements for Control of Procurement of Items and Services for Nuclear Power Plants (Rev. 1)". Can anyone tell me what the basis was for withdrawing these guides? Thanks in advance. Larry Barten

 

 

Date: Fri, 7 Aug 1998

Subject: NRC Regulatory Guides

Hi Larry: According to NRC letter dated June 17, 1991, all three regulatory guides in question were withdrawn, along with three others (1.64, 1.144, and 1.146), because they had become obsolete and incorporated into ANSI/ASME NQA-1-1983 entitled "Quality Assurance Program Requirements for Nuclear Facilities". However as indicated in the letter, the withdrawal of these regulatory guides does not alter any prior or existing licensing commitments based on their use". Hope this helpful. Frank
