Full title and description

St ASTM C757-06 (2011)e1 rus — Russian-language edition (translation) of ASTM C757-06(2011)e1: "Standard Specification for Nuclear‑Grade Plutonium Dioxide Powder, Sinterable" (Russian translation of the 2006 standard as reapproved/edited in 2011).

Abstract

This document specifies requirements for nuclear‑grade plutonium dioxide (PuO2) powders intended for fabrication into light‑water reactor fuel (sinterable powders). It covers acceptable production routes (for example oxalate precipitation and calcination), isotopic composition limits, chemical impurity limits (selected metallic and non‑metallic impurities and equivalent boron), gamma activity constraints, and physical properties such as cleanliness, particle size distribution and surface area. The standard notes that it does not itself address criticality prevention, health/safety controls, or transport regulations.

General information

• Status: Edition C757‑06 (reapproved/edited 2011, e1). This edition has since been superseded by a later revision (ASTM C757‑16 and subsequent reissues); the Russian translation corresponds to the 2006/2011 text.
• Publication date: Original approval 2006; reapproved/edited version dated January 6, 2011 (designated C757‑06(2011)e1).
• Publisher: ASTM International (translation published/distributed by third‑party translation/document vendors as indicated by the "rus" edition).
• ICS / categories: 27.120.30 — Fissile materials and nuclear fuel technology (nuclear materials/specifications).
• Edition / version: C757‑06 (Reapproved 2011) with editorial change e1 — Russian translation edition of that version.
• Number of pages: Approximately 3 pages (concise specification document).

Scope

The standard applies to sinterable nuclear‑grade PuO2 powders of various isotopic compositions as normally prepared for light‑water reactor fuel fabrication. It defines chemical and radiological composition limits (including plutonium, uranium, americium and selected impurities), physical property requirements (cleanliness, particle size distribution, surface area), and quality‑assurance expectations for production. It explicitly excludes operational safety, criticality prevention procedures, and transport/shipping requirements, which remain the responsibility of users and regulators.

Key topics and requirements

• Definition of acceptable production routes (oxalate precipitation, calcination, or equivalent processes).
• Isotopic composition limits and homogeneity requirements for plutonium and other actinides.
• Chemical impurity limits (examples: boron, cadmium, carbon, chlorine, chromium, fluorine, iron, gadolinium, nickel, nitrogen (as nitride), thorium) and equivalent‑boron specification.
• Gamma‑activity and radiological controls / acceptance criteria for nuclear‑grade material.
• Physical property criteria: cleanliness (free of visible foreign fragments), particle size distribution (sieve/percent passing requirements), and specific surface area.
• Requirement that material be produced under a quality assurance program acceptable to the buyer.
• Statement that SI units are standard and that the specification does not replace regulatory safety or transport obligations.

Typical use and users

Used by MOX and fuel fabrication facilities, nuclear fuel designers, fuel cycle laboratories, regulators, procurement/specification engineers in utilities and fuel vendors, and researchers working on plutonium oxide fuels. The Russian translation is intended for Russian‑language users who need to apply or review the 2006/2011 edition text.

Related standards

Standards commonly referenced with this specification include ASTM test methods and specifications for analysis and characterization of plutonium and uranium materials (for example ASTM C697 and other committee C26 documents), related fuel specifications (such as standards for sintered UO2 / MOX pellet materials), and relevant ISO/national test methods for PuO2 composition analysis and particle characterization. Later revisions of the C757 series (notably ASTM C757‑16 and reissues) supersede the 2006/2011 text for current procurement.

FAQ

Q: What is this standard?

A: It is the ASTM specification C757 in the 2006 edition as reapproved/edited in 2011 (designation C757‑06(2011)e1), provided here in a Russian‑language translation. The document defines acceptance criteria for nuclear‑grade plutonium dioxide powder intended for sintering into reactor fuel.

Q: What does it cover?

A: Chemical and isotopic composition limits, selected impurity limits including equivalent boron, radiological (gamma activity) considerations, and physical properties such as cleanliness, particle size distribution and surface area for sinterable PuO2 powders. It does not provide procedures for preventing criticality, health/safety rules, or transportation regulations.

Q: Who typically uses it?

A: Fuel fabricators, nuclear materials laboratories, procurement/specification engineers, regulators, and researchers involved in MOX or plutonium‑bearing fuel manufacture and characterization. The Russian translation is for Russian‑language users needing the 2006/2011 text.

Q: Is it current or superseded?

A: The C757‑06(2011)e1 text has been superseded by a later revision (ASTM C757‑16 and subsequent reissues). For procurement or regulatory compliance, users should confirm whether the later C757 revision is required; the Russian translation here reflects the 2006/2011 edition.

Q: Is it part of a series?

A: Yes — it is part of the ASTM C series (committee C26 on Nuclear Fuel Cycle), which includes related specifications and test methods for nuclear materials and fuel characterization. This designation is one version in the C757 revision history.

Q: What are the key keywords?

A: plutonium dioxide, PuO2, nuclear‑grade, sinterable powder, MOX, light water reactors, impurities, particle size, ASTM C757, Russian translation.
