# nrc.reactor.current_status

Get the latest daily power output for all ~95 US commercial nuclear reactor units as reported by the US Nuclear Regulatory Commission (NRC). Returns each reactor's current power level as a percentage of licensed thermal power (0–100%), operational status (full_power / reduced_power / shutdown), and fleet-wide summary counts. Data is updated each business day M–F and reflects the previous day's reported capacity. Essential for US energy grid monitoring, nuclear generation capacity dashboards, and power market analysis. No auth — US NRC public domain data (Atomic Energy Act), unlimited free.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `sort_by` | string | no | Sort order for the reactor list. "name" (alphabetical, default), "power_asc" (lowest power first), "power_desc" (highest power first). |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "nrc.reactor.current_status",
    "arguments": {}
  }
}
```

## Why nrc.reactor.current_status is rated Low

Retrieves public nuclear reactor status data from NRC without side effects or modifications.

From the tool's own definition: "Get the latest daily power output, current power level, operational status, fleet-wide summary counts"

## Use case

AI agents call nrc.reactor.current_status to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "nrc.reactor.current_status": {}
  }
}
```
