Verify whether the yard fire hydrants are in scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and not subject to an AMR, provide justification for the exclusion.
RAI 2.3.3.8-1 Revised Response The yard fire hydrants are in scope and subject to aging management review. The hydrants are identified as component type "valve body" in LRA Table 2.3.3-8. Results of the aging management review are provided in LRA Table 3.3.2-8 for line items "Valve body" with carbon steel as the material and raw water as the environment.
Additional Information The revised response to RAI 2.3.3.8-1 supersedes the response in Attachment 1 of LRA Amendment 14'and the-additional information in Attachment 3 of LRA Amendment 19.

KJŽonathan Rowley_-BVY 06-1 00-VY LRA Am. 22 Environmental and AMP-AMR Audit Question Clarification.PDF I OWU U I1 VERMONT YANKEE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION ATrACHMENT 2 During review of Vermont Yankee's Environmental Report, a 2004 Clean Water Act 316(a) Demonstration, and in discussions with team members from Argonne National Laboratory, it has been determined that a correction to Vermont Yankee Nuclear Power Station's (VYNPS) Environmental Report is appropriate. Specifically, Section 2.2; "Aquatic and Riparian Ecological Communities", the fast paragraph of page 2-2 shall be changed'as follows:
Water temperatures as measured near VYNPS vary from 32°F to 84°F with daily variations rarely exceeding 2*F. From December through March the water temperature averages 350F, and from July through September it averages between 70'F to 771F (Reference 2-2,Section II.E.2]. Based on a 316(a)
Demonstration conducted in support of a request for increased discharge temperature limits between May 15 and October 14 annually, it was determined that the River water was thoroughly mixed below Vernon Dam and therefore thermal stratification was highly unlikely [Reference 2-15, Section 3.2.4]. Thermal stratification is observed in the portion of the Connecticut River known as lower Vernon pool due to the contribution of solar input and Vermont Yankee's thermal discharge. Thermal stratification from solar input alone is also observed upstream of and outside of the influence of Vermont Yankee's thermal discharge.

The staff requests that the applicant provide actual values of pH, chlorides, and sulfates in the groundwater/soil adjacent to structures in order to verify the claim of a non-aggressive below-grade environment.

require measurement of sulfate levels. License renewal commitment 33 ensures that groundwater samples will continue to be evaluated on a periodic basis to assess aggressiveness of groundwater to concrete. This commitment is revised as follows (bold words added) to specify that future samples will be monitored for sulfates along with pH and chlorides.
Included within the Structures Monitoring Program are provisions that will ensure an engineering evaluation is made on a periodic basis (at least once every five years) of groundwater samples to assess aggressiveness of groundwater to concrete. Samples will be evaluated for sulfate, pH and chloride levels.
The Vermont Agency of Natural Resources has attributed the difference in chloride levels between Well 3301 and Well 3401 to road salt influence given the close proximity of Well 3301 to a roadway within the plant boundaries.

ILJonathan Rowley - BVY 06-100 - VY LRA Am. 22 Environmental and AMP-AMR Audit Question Clarification.PDF 2Page i2 VERMONT YANKEE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION ATTACHMENT 4 Additional Clarification Audit item 350 NRC question states; B.1.27.3-E-01 Please clarify the FERC provisions under which the Vernon Dam is inspected. The dam is now exempt from Provisions of Title 18, Part 12, Subpart D, (Inspection by Independent Consultant).
Clarification: Audit item 350 (provided in LRA Amendment 5, dated July 14, 2006, addressing "LRA Section A.2.1.31, Structures Monitoring - Vernon Dam FERC Program"), has been revised to state the following.
"The Vernon dam is subject to the Federal Energy Regulatory Commission (FERC) inspection program. This program consists of visual inspections in accordance with FERC guidelines and complies with Title 18 of the Code of Federal Regulations, Conservation of Power and Water Resources, Part 12 (Safety of Water Power Projects and Project Works) and Division of Dam Safety and Inspections Operating Manual. The inspection frequency for licensed and exempt low hazard potential dams is biennial. As indicated in NUREG-1801 for water control structures, NRC has found that FERC /,US Army Corp of Engineers dam inspections and maintenance programs are acceptable for aging management."'
