What this category of data looks like
Nuclear power operations business documents are primarily sourced from on-site operating procedures, equipment maintenance logs, business approval forms, and safety review reports. Data updates follow quarterly maintenance plans, annual safety compliance reviews, and immediate applications initiated by daily business activities. Most documents use fixed structured formats, including fields such as equipment number, approval node, and time limit requirement. Units include professional measurement standards such as hours, sets, and megapascals. Some long documents include step-by-step instructions for process nodes.
What Constraints These Characteristics Impose on the Document Parsing and Chunking Link
The structured nature of nuclear power operation documents requires retaining field associations during parsing, to avoid splitting that breaks the contextual logic of approval nodes. The presence of professional measurement terms and fixed formats requires parsing tools to identify professional field boundaries, to prevent splitting that separates equipment numbers from corresponding operation requirements. Handling long documents and batch business forms at the same time increases single-document parsing time, requiring chunking to balance the integrity of single-block business, to avoid splitting across nodes that disrupts process guidance logic. Some cross-page process description documents need to retain cross-page content connections, to prevent discontinuous process steps after chunking. Frequently updated immediate application forms require the parsing link to adapt to fast batch processing rhythm, to avoid affecting the timeliness of business guidance.
How to Configure Settings
The following configurations are formulated for FastGPT v4.17.0.
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the length of professional paragraphs in nuclear power documents, retains complete contextual information of business nodes |
chunkSplitter | Split by paragraph + title boundaries | Matches the structured chapters of nuclear power documents, avoids splitting that disrupts logical connections of approval processes |
customPdfParse | Enable structured parsing mode | Identifies form fields and professional units in documents, preserves data integrity |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports batch uploads of large equipment maintenance logs and annual safety reports |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Meets parsing time requirements for long documents and batch forms |
chunkSettingMode | Manual configuration mode | Adjusts chunking rules for the specialized formats of nuclear power documents, adapts to contextual requirements for business guidance |
Three Common Misconfigurations
- Phenomenon: Large batch document uploads are interrupted during parsing, and parsing cannot continue after restarting the container. Cause: The
UPLOAD_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDSconfigurations are not adjusted, leading to forced termination of the parsing process due to exceeding system processing thresholds. - Phenomenon: No parsing progress feedback is displayed after uploading a file via the dialog box, and no error logs are generated in the background. Cause: The structured parsing mode of
customPdfParseis not enabled, so non-standard format documents cannot be identified to trigger the parsing process. - Phenomenon: Parsed documents cannot be used by the model to answer business questions. Cause: The
chunkSizeconfiguration is too small, which splits complete business process nodes during parsing, preventing the model from associating contextual information.
How to Verify Proper Configuration
- Upload a single nuclear power equipment maintenance log document within 1000 MB, and check whether the parsing progress completes normally.
- View the parsing configuration panel, confirm that
customPdfParseis enabled, and thechunkSizevalue meets the length requirements of business documents. - Upload batch business forms, and verify that the parsing time does not exceed the configured value of
PARSE_FILE_TIMEOUT_SECONDS. - Extract the chunked content after parsing, and check whether core business fields such as equipment number and approval node are retained.
