What this category of data looks like
Documents related to nuclear power operations service inquiries and responses mainly come from internal operation procedures, emergency response manuals, notifications from superior regulatory units, and operation work orders and inquiry response records stored in internal multi-dimensional tables. Update frequency: Procedure documents are revised quarterly or annually. Work orders and real-time inquiry records are updated in real time with business activities. Notification documents are updated when issued. Document structures typically include chapter numbers, clause descriptions, applicable positions, and engineering parameters. Fields include document number, effective date, and corresponding unit number. Units involve professional metric values such as MPa, ℃, and operating hours.
What constraints do these characteristics impose on the document parsing and chunking stage
Long-form operation procedures must avoid excessive splitting that breaks clause context. Professional parameters and chapter numbers must be accurately identified to ensure complete chunk semantics. Real-time updated work orders and inquiry records require fast parsing capabilities. Large-volume PDF documents require adapted parsing durations. Documents with embedded tables and engineering drawings require custom parsing logic. Otherwise, content loss or formatting errors may occur, affecting accurate matching for subsequent inquiry responses.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Nuclear power operation documents contain long paragraphs and professional parameters; this range avoids splitting that compromises clause integrity |
chunkSplitter | By title hierarchy and paragraph | Documents have clear chapter numbers and clause structures, preserving contextual associations |
customPdfParse | Enabled | Nuclear power documents often contain embedded tables, engineering formulas, and drawings; custom parsing is required to adapt to professional formats |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single procedure files have large volume and multiple parsing steps; this avoids timeout interruptions to the parsing process |
chunkSettingMode | Manual configuration | Parameters must be adjusted for different document types such as procedures, work orders, and notifications to adapt to professional scenarios |
Three common mistakes
- Calling the parsing interface returns empty results. The cause is that
customPdfParseis not enabled, so embedded engineering tables and formulas in nuclear power documents cannot be parsed correctly. - A timeout error (status code 504) occurs during parsing. The cause is that
PARSE_FILE_TIMEOUT_SECONDSis not adjusted to a duration suitable for large-volume files. - Chunk results contain content spliced across chapters. The cause is that
chunkSplitteris not set to split by title hierarchy, causing adjacent unrelated clauses to be merged.
How to confirm configurations are correctly set
- Upload a single operation procedure with more than 100 pages. Confirm that parsing completes normally with no timeout-related errors.
- Review the chunked result list. Confirm that each chunk contains complete clauses and associated professional parameters, with no cross-chapter spliced content.
- Call the FastGPT official document library pull interface. Confirm that the returned file list includes the target nuclear power operation and maintenance related documents.
- Test the multi-file upload interface. Confirm that procedure, work order, and notification documents can be submitted simultaneously and parsed successfully.
