# §59.506. How do I demonstrate compliance if I manufacture multi-component kits?

- (a) If you manufacture multi-component kits as defined in [§ 59.503](/cfr/40/59.503.md), then the Kit PWR must not exceed the Total Reactivity Limit.
- (b) You must calculate the Kit PWR and the Total Reactivity Limit as follows:
  - (1) **KIT PWR = (PWR<I>(1)</I> × W<I>1</I>) + (PWR<I>(2)</I> × W<I>2</I>) + .** ... + (PWR(n) × Wn)
  - (2) Total Reactivity Limit = (RL1 × W1) + (RL2 × W2) + ... + (RLn × Wn).
  - (3) **Kit PWR ≤Total Reactivity Limit.**
