OF SITE AUDIT TO SUPPORT THE LICENSE RENEWAL REVIEWFOR THE NATIONAL BUREAU OF STANDARDS REACTOR (NBSR) AT THENATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGYThe NBSR is licensed under 10 CFR 50.21(c) as a testing facility, which is defined in10 CFR 50.2. "Criteria for and identification of licensing and regulatory actions requiringenvironmental impact statements" in 10 CFR 51.20, states that an environmental impactstatement is needed for "[i]ssuance or renewal of a full power or design capacity license tooperate a nuclear power reactor, testing facility, or fuel reprocessing plant pursuant to part 50 ofthis chapter. Therefore, the license renewal for the NBSR requires that an environmentalimpact statement (EIS) must be prepared as part. An environmental review team consisting ofNuclear Regulatory Commission (NRC) staff and contractors from Pacific Northwest NationalLaboratory (PNNL) conducted site audit activities at the National Bureau of Standards Reactor(NBSR) located at the NIST Center for Neutron Research (NCNR) on the National Institute ofStandards and Technology (NIST) campus on September 26, 2006, to support theenvironmental review of the NIST license renewal (LR) application. The environmental reviewteam consisted of three contractors from PNNL and three Nuclear Regulatory Commission(NRC) staff. The primary goals of the site visit were to tour the site and environs; to discuss theEnvironmental Report (ER) submitted as part of the application by NIST; and to gatheradditional information to ensure that the requirements of 10 CFR Part 51 are met. A list of thenames and affiliations of those participating in the NBSR site audit at the NIST site is providedas Enclosure 1.The environmental review team participated in an initial introductory overview meeting with theNBSR staff at the NIST Center for Neutron Research on Tuesday, September 26, 2006. NBSR staff presented a brief overview of the site, conducted a tour of the NBSR facility andassociated Cold Neutron Guide Hall and the surrounding environment focusing on areasrelevant to the environmental review. These areas included the cooling towers, the receivingarea, the parking area, the waste water storage area, a drainage pond, temporary wastestorage area and a viewing of the meteorological tower.

SUMMARY

OF SITE AUDIT TO SUPPORT THE LICENSE RENEWAL REVIEW FOR THE NATIONAL BUREAU OF STANDARDS REACTOR (NBSR) AT THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY The NBSR is licensed under 10 CFR 50.21(c) as a testing facility, which is defined in 10 CFR 50.2. Criteria for and identification of licensing and regulatory actions requiring environmental impact statements in 10 CFR 51.20, states that an environmental impact statement is needed for [i]ssuance or renewal of a full power or design capacity license to operate a nuclear power reactor, testing facility, or fuel reprocessing plant pursuant to part 50 of this chapter. Therefore, the license renewal for the NBSR requires that an environmental impact statement (EIS) must be prepared as part. An environmental review team consisting of Nuclear Regulatory Commission (NRC) staff and contractors from Pacific Northwest National Laboratory (PNNL) conducted site audit activities at the National Bureau of Standards Reactor (NBSR) located at the NIST Center for Neutron Research (NCNR) on the National Institute of Standards and Technology (NIST) campus on September 26, 2006, to support the environmental review of the NIST license renewal (LR) application. The environmental review team consisted of three contractors from PNNL and three Nuclear Regulatory Commission (NRC) staff. The primary goals of the site visit were to tour the site and environs; to discuss the Environmental Report (ER) submitted as part of the application by NIST; and to gather additional information to ensure that the requirements of 10 CFR Part 51 are met. A list of the names and affiliations of those participating in the NBSR site audit at the NIST site is provided as Enclosure 1.

The environmental review team participated in an initial introductory overview meeting with the NBSR staff at the NIST Center for Neutron Research on Tuesday, September 26, 2006.

NBSR staff presented a brief overview of the site, conducted a tour of the NBSR facility and associated Cold Neutron Guide Hall and the surrounding environment focusing on areas relevant to the environmental review. These areas included the cooling towers, the receiving area, the parking area, the waste water storage area, a drainage pond, temporary waste storage area and a viewing of the meteorological tower. The NBSR team provided the review team with several documents containing information in response to information requests. lists these documents and associated ADAMS accession numbers.

At the conclusion of the NBSR site audit, the NRC and its contractor staff from PNNL summarized the information and documents needed to complete the environmental review. summarizes information given verbally during the site visit and confirmed in writing by email upon which the review team will rely in preparing its draft EIS.

The NRC and contractor staff are continuing the NBSR environmental review and plan to publish a draft EIS in early 2007.
