Rancho Seco License Termination Plan Revision 1 Glossary of Terms, Acronyms and Abbreviations May 2008 Glossary of Terms Background Radiation - Radiation from cosmic sources, naturally occurring radioactive material, and global fallout, which contributes to the background radiation.

Containment Building - The building during plant operation that contained the reactor vessel, steam generators, pressurizer, reactor coolant pumps, and other systems.

Contamination - Deposition of reactor-generated radioactive material.

Corrective Action Records - Documentation for occurrences or events that recognized safety related deficiencies, identified conditions adverse to quality, or were reportable to regulatory agencies. Corrective action documentation includes evaluations, actions, results and responses that were associated with an event or condition that documented in License Event Reports (LERs), Occurrence Description Reports (ODRs), Non-Conformance Reports (NCRs), Potential Deviations from Quality (PDQ) or Deviation from Quality (DQ).

DCGL - (derived concentration guideline level) The derived radionuclide-specific activity concentration that corresponds to the release criterion (25mrem/y) within a survey unit.

Deterministic treatment - While using RESRAD-BUILD in the probabilistic mode, deterministic treatment is the assignment of a single conservative value to a parameter rather than a statistical distribution.

Health Physics Logbook - The logbook detailing the day-to-day site Health Physics activities.

Impacted Area - Any area that is not classified as non-impacted. Areas with a reasonable possibility of containing residual radioactivity in excess of natural background or fallout levels.

Industrial Area - The land area of potential radiological and non-radiological impact is that portion of the site where licensed activities took place. This location encompasses approximately 87 acres and includes the power block, the interim onsite radwaste storage building, and adjacent support structures and transport routes.

Independent Spent Fuel Storage Installation (ISFSI) - The area that contains the dry fuel storage facility.

Non-Impacted Area - An area where there is no reasonable possibility (extremely low probability) for residual radioactivity to exist.

pCi/g - Picocurie per gram, a concentration scale typically used in the measurement of radioactivity in soil.

Piezometer - A type of groundwater well used to measure differences in hydrostatic pressure in aquifers.

Rancho Seco License Termination Plan Revision 1 Glossary of Terms, Acronyms and Abbreviations May 2008 PRCC - Partial ranked correlation coefficient - Estimates nonlinear monotonic relationship and gives the unique contribution of an input parameter to the resultant dose.

Residual Radioactivity - Radioactivity in structures, materials, soil, groundwater and other media at a site resulting from activities under the licensees control. This includes radioactivity from all licensed and unlicensed sources used by the licensee. It also includes radioactive materials remaining at the site as a result of routine or accidental releases. Residual radioactivity does not include background radiation from naturally occurring isotopes or fallout from nuclear bomb testing.

SAFSTOR - The alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use.

Scoping Survey - An initial survey performed to evaluate: 1) radionuclide contaminants,

2) relative radionuclide ratios, and 3) general levels and extent of contamination.

Single nuclide DCGL - A radionuclide-specific activity concentration that would result in an annual total effective dose equivalent (TEDE) dose of 25 mrem with no other radionuclides present.

Stochastic treatment - While using RESRAD or RESRAD-BUILD in the probabilistic mode, stochastic treatment is the assignment of a statistical distribution for the value of a RESRAD or RESRAD-BUILD parameter.

Turbine Building - The building that once contained the condensate feed pumps, condensate demineralizers, moisture separators, feedwater heaters and main turbine generator.

Unity rule (mixture rule) - A rule applied when more than one radionuclide is present at a concentration that is distinguishable from background and where a single concentration comparison does not apply. In this case, the mixture of radionuclides is compared against default concentrations by applying the unity rule. This is accomplished by determining: 1) the ratio between the concentration of each radionuclide in the mixture, and 2) the concentration for that radionuclide in an appropriate listing of default values. The sum of the ratios for all radionuclides in the mixture should not exceed 1.
